Plug your gear in, hope you don’t get a lightning strike, replace it every few years when the indicator light goes out. For a desk lamp and a phone charger, that’s plenty. For a $1,500 receiver, a 4K display, a streaming box, and a turntable, it really isn’t.\u003c\/p\u003e\n\n\u003cp\u003eThe PST series is what happens when a company that’s been engineering AC power products for broadcast studios and live-sound rigs since 1974 decides to make a power strip. The technology stack varies by model — the PST-8 and PST-8D bring the full Powell-engineered SMP \/ LiFT \/ EVS protection found in Furman’s higher-end Elite line, while the PST-6 and PST 2+6 use a simpler but still genuinely upgraded MOV-based circuit with RFI\/EMI filtering. Either way, you’re getting better engineering than the commodity surge strip the buyer was likely replacing, in a form factor that fits the same cable run behind the same equipment rack.\u003c\/p\u003e\n\n\u003cp\u003eTwo things every PST shares. First, \u003cstrong\u003ezero ground contamination\u003c\/strong\u003e: a Furman-specific circuit choice that does not shunt surge energy onto your circuit ground (the way most MOV-based strips do), so your DAC, streamer, and other digital gear don’t have garbage on their ground reference. Second, \u003cstrong\u003esignal-line protection\u003c\/strong\u003e: every PST includes coaxial (cable\/satellite) and telephone surge inputs, because lightning that comes in through the cable line will fry a TV just as effectively as lightning that comes through the wall. \u003cem\u003eIn our experience, a good power conditioner or low-noise power supply will almost always noticeably improve the sound of any high-end audio system\u003c\/em\u003e, and the same engineering principles that make Furman’s higher-end conditioners audible also drive the design of their power strips.\u003c\/p\u003e\n\n\u003ch3\u003eWhat Makes the PST-8 the Right Pick\u003c\/h3\u003e\n\u003cp\u003eThe PST-8 is where the \u003cstrong\u003efull Powell-engineered technology stack\u003c\/strong\u003e arrives in the PST line. The PST 2+6 and PST-6 use a fused-MOV-plus-RFI-filter circuit that’s better than a commodity surge strip but is genuinely entry-level. The PST-8 is fundamentally a different product:\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNon-sacrificial SMP surge protection.\u003c\/strong\u003e Same circuit topology as the Furman Elite series of power conditioners. Most surge protectors — including the PST 2+6 and PST-6 in this same family — use MOVs that absorb a hit and degrade in the process. SMP is engineered to clamp surges \u003cem\u003ewithout sacrificing itself\u003c\/em\u003e, so the PST-8 keeps protecting through repeated large events rather than silently failing on the first one.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiFT (Linear Filtering Technology).\u003c\/strong\u003e A linear low-pass filter tuned to attenuate AC line noise smoothly across a wide frequency range — greater than 40 dB from 150 kHz to 100 MHz, and greater than 80 dB across 100 kHz to 1 GHz. That’s a substantial step up from the PST-6’s basic RFI\/EMI filter, and it’s the part you can actually hear on a high-resolution audio system: cleaner backgrounds, more low-level detail.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEVS (Extreme Voltage Shutdown).\u003c\/strong\u003e A circuit that monitors the incoming AC line and cuts power to all eight outlets if the voltage drifts above approximately 135 to 137 volts. Sustained over-voltage events — utility transformer faults, miswired generators, certain solar-grid-tie scenarios — cause more cumulative damage to audio gear than surges do, and EVS is specifically designed to stop them. The PST-6 and PST 2+6 don’t have this; the PST-8 does.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eThe chassis is aluminum, captured in the same general form factor as the PST-6 but stretched to fit eight outlets. The 8-foot captive cord with the 36-degree angled NEMA plug carries through from the entry tier. If you want full Furman protection engineering — same surge-clamping and noise-filtering technology used in the Elite series — in a power-strip form factor at a fraction of the price of an Elite-15i, the PST-8 is the answer. The only step-up from here within the PST family is the PST-8D, which adds isolated outlet banks for systems with both digital and analog gear.\u003c\/p\u003e\n\n\u003c!-- POWELL LINEAGE --\u003e\n\u003cp\u003eOne footnote worth mentioning: the engineer who developed Furman’s SMP, LiFT, and broader power-product circuit design is Garth Powell. Powell spent years refining Furman’s AC products before moving on to lead power-product engineering at AudioQuest, where his work on the Niagara line carries forward many of the same design principles. When you buy a Furman from this era, you’re buying into that engineering lineage — even at the entry level.\u003c\/p\u003e\n\n\u003c!-- THE TECHNOLOGY INSIDE --\u003e\n\u003ch2\u003eThe Technology Inside the PST-8\u003c\/h2\u003e\n\n\u003ch3\u003eSeries Multi-Stage Protection (SMP) — Non-Sacrificial Surge Protection\u003c\/h3\u003e\n\u003cp\u003eThis is the centerpiece of the PST-8 and PST-8D. Most power strips and surge protectors rely on MOVs that physically sacrifice themselves when they absorb a large spike — after one big surge, the protection is used up even though the indicator light still glows. \u003cstrong\u003eFurman’s SMP circuit is non-sacrificial\u003c\/strong\u003e: it clamps surges without destroying itself, so one PST keeps protecting after hit after hit. SMP is the same surge-protection technology Furman uses in its higher-end Elite series of power conditioners, packaged here in a power-strip form factor at a fraction of the price.\u003c\/p\u003e\n\n\u003ch3\u003eLinear Filtering Technology (LiFT) — Noise Reduction Without Choking Dynamics\u003c\/h3\u003e\n\u003cp\u003eMost “filtered” surge strips use simple non-linear filters that produce a narrow notch-and-ring response — they reduce some noise, but they also introduce resonant peaking that can actually \u003cem\u003eadd\u003c\/em\u003e noise in places. Furman’s \u003cstrong\u003eLiFT\u003c\/strong\u003e circuit is a linear low-pass filter engineered to attenuate AC line noise smoothly across a wide frequency band: greater than 40 dB from 150 kHz to 100 MHz, and greater than 80 dB across the 100 kHz to 1 GHz range. In practical terms: cleaner AC, no resonant peaking, no current limiting that would squeeze your amplifier’s dynamics.\u003c\/p\u003e\n\n\u003ch3\u003eExtreme Voltage Shutdown (EVS) — Protection from Sustained Over-Voltage\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eEVS\u003c\/strong\u003e monitors the incoming line and cuts power to everything downstream if the voltage drifts above approximately 135 to 137 volts — the threshold where a sustained over-voltage condition (utility transformer fault, miswired generator, neighbor pulling power on a shared circuit) starts to cause cumulative damage to gear. Brownouts and sustained over-voltage events damage more audio equipment than surges do, and EVS is specifically designed to stop them before your amp’s power supply ever sees them.\u003c\/p\u003e\n\n\u003ch3\u003eZero Ground Contamination\u003c\/h3\u003e\n\u003cp\u003eOlder surge-protection designs shunt surge energy to circuit ground, which sounds reasonable until you realize that your DAC, streamer, and other digital sources all reference signal to that same ground. Garbage on the ground rail shows up in the listening chair as hum, hash, and a slightly elevated noise floor. Furman’s circuit design deliberately avoids this — surges are clamped without dumping anything to ground.\u003c\/p\u003e\n\n\u003c!-- BUILD QUALITY --\u003e\n\u003ch3\u003eBuild Quality and the Metal Chassis\u003c\/h3\u003e\n\u003cp\u003eOne thing that sets the PST-6, PST-8, and PST-8D apart from most surge protectors in their price range: the chassis is \u003cstrong\u003ealuminum\u003c\/strong\u003e, not plastic. Walk into any office-supply store and you’ll find a wall of plastic-cased surge strips — flimsy, cheap to mold, prone to creaking when an outlet fits tightly, and offering essentially zero EMI shielding. Furman’s metal chassis brings real benefits: structural rigidity that doesn’t deform under power-cord pull, vibration damping for the internal components, and a continuous metallic enclosure that contributes to RF shielding for the protection and filtering circuitry inside.\u003c\/p\u003e\n\n\u003cp\u003eThe captive 8-foot power cord is also a step above commodity practice — heavier-gauge wire than the typical 16-AWG cord on a $25 strip, with a 36-degree NEMA 5-15 plug (angled away from the wall to make installation cleaner behind furniture). Small things, but the kind of thing you notice when you’re routing a permanent install.\u003c\/p\u003e\n\n\u003c!-- FAQ --\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003ch3\u003eHow is this different from a $25 surge strip from an office store?\u003c\/h3\u003e\n\u003cp\u003eThree meaningful ways. (1) \u003cstrong\u003eSurge protection that actually keeps working.\u003c\/strong\u003e Generic strips use sacrificial MOVs that silently degrade after large hits — your indicator light says “protected” while the protection has actually failed. Furman uses non-sacrificial SMP on the PST-8, designed to keep protecting after repeated hits. (2) \u003cstrong\u003eRFI\/EMI filtering.\u003c\/strong\u003e Generic strips do nothing about the noise riding on your AC line; the PST series filters that noise across the audio-sensitive frequency range. (3) \u003cstrong\u003eZero ground contamination.\u003c\/strong\u003e Generic strips shunt surge energy to ground, which can actually \u003cem\u003eadd\u003c\/em\u003e noise to your digital sources. Furman’s design avoids that.\u003c\/p\u003e\n\n\u003ch3\u003eWhich PST should I buy?\u003c\/h3\u003e\n\u003cp\u003eQuick guide: \u003cstrong\u003ePST 2+6\u003c\/strong\u003e if you want Furman protection in the most affordable form factor and you value the audible surge alarm and diagnostic LEDs (plastic chassis, 8 outlets including 2-3 spaced for wall-warts). \u003cstrong\u003ePST-6\u003c\/strong\u003e if you want a metal-chassis Furman in a 6-outlet configuration with the same entry-tier protection circuit. \u003cstrong\u003ePST-8\u003c\/strong\u003e if you want the full SMP \/ LiFT \/ EVS technology stack — same protection found in the Elite series, in a power-strip form factor with 8 outlets in one bank. \u003cstrong\u003ePST-8D\u003c\/strong\u003e if you have a system with both digital gear (TV, streamer, AVR) and analog gear (turntable, integrated amp) and you want the two banks isolated from each other to keep digital noise out of the analog chain.\u003c\/p\u003e\n\n\u003ch3\u003eWill this limit my amplifier’s current?\u003c\/h3\u003e\n\u003cp\u003eFor the audio gear most people plug into a Furman power strip — receivers, integrated amps, source components, displays — no. The 15-amp current rating across all outlets is plenty of headroom for typical home systems. Where you’d run into trouble is plugging a pair of high-current monoblock power amplifiers into a Furman PST and expecting them to deliver full transient performance — that’s not what these are designed for, and you’d want a higher-end conditioner with a Power Factor Technology bank (the Furman Elite-15 PFi or Elite-20 PFi) for that application. For everything else, the PST series is correctly sized.\u003c\/p\u003e\n\n\u003ch3\u003eWhy are the cable and phone connectors on this thing?\u003c\/h3\u003e\n\u003cp\u003eLightning that comes in through your coax cable line or telephone line will fry a TV or modem just as effectively as lightning that comes through the wall outlet. The PST series includes \u003cstrong\u003esignal-line surge suppression\u003c\/strong\u003e for one cable\/satellite coax connection and one telephone line — pass-through connectors that surge-protect those signals before they reach your gear. If you don’t have cable TV or a landline, you can simply ignore those connectors. If you do, they’re a useful inclusion that most generic surge strips lack entirely.\u003c\/p\u003e\n\n\u003ch3\u003eWhat’s the warranty?\u003c\/h3\u003e\n\u003cp\u003eFurman backs the PST series with a 1-year limited warranty covering defects in materials and workmanship.

It was built for light bulbs and electric motors. It was never built for the audio and video gear we use today.\u003c\/p\u003e\n\u003cp\u003eModern homes are full of noise on the AC line. WiFi, cell signals, dimmer switches, LED bulbs, and computer power supplies all add electrical noise — and so do your neighbors’ homes.\u003c\/p\u003e\n\u003cp\u003eAudioQuest has measured what this does. Up to a third of a high-resolution audio signal can be lost or covered up by AC noise before it ever reaches your speakers. Once that detail is gone, no other piece of gear can bring it back.\u003c\/p\u003e\n\u003cp\u003eA power conditioner sits between the wall and your equipment. It filters out the noise, gives your amp the current it needs on big musical peaks, and protects your gear from voltage spikes and surges.\u003c\/p\u003e\n\u003cp\u003eIn our experience, a good power conditioner will almost always noticeably improve the sound of any high-end audio system. The PowerQuest 707 delivers that improvement at a price that puts real AudioQuest power engineering within reach. And it ships with a proper AudioQuest power cable already in the box.\u003c\/p\u003e\n\u003ch3\u003eWhat Makes the PowerQuest 707 Notable?\u003c\/h3\u003e\n\u003cp\u003eThe PowerQuest 707 was designed by Garth Powell, AudioQuest’s Senior Director of Engineering — the same designer behind the reference Niagara line. It was the original flagship of the PowerQuest series.\u003c\/p\u003e\n\u003cp\u003eEven with the PowerQuest 909 above it now, the 707 retains one of the most important features Powell’s Niagara work introduced: a big reservoir of on-demand transient current for your power amp.\u003c\/p\u003e\n\u003ch3\u003e45 Amps of Transient Power Correction — on a PowerQuest\u003c\/h3\u003e\n\u003cp\u003eOne Alpha Audio reviewer described it this way: the 707 contains a kind of “battery” that can deliver up to 45 amps of current on demand, the moment your amp needs it for a big musical peak.\u003c\/p\u003e\n\u003cp\u003eMost conditioners in this price range choke your amp’s dynamics. The 707 was designed to avoid that, with four dedicated High-Current outlets backed by Transient Power Correction. This is the same core idea behind AudioQuest’s much pricier Niagara line.\u003c\/p\u003e\n\u003ch3\u003eUltra-Linear Noise-Dissipation — Greater Than −22 dB\u003c\/h3\u003e\n\u003cp\u003eThe 707 attacks AC line noise across a wide bandwidth rather than one narrow band. It runs both a 30 kHz – 1 GHz Differential Mode filter and a 30 kHz – 1 GHz Common Mode filter.\u003c\/p\u003e\n\u003cp\u003eTogether they address the two kinds of noise that most commonly plague AC power. What this means: quieter backgrounds, better fine detail, sharper imaging.\u003c\/p\u003e\n\u003ch3\u003eTwelve Outlets, Split into Two Purpose-Built Banks\u003c\/h3\u003e\n\u003cp\u003eFour High-Current outlets with Transient Power Correction for your amplifier, integrated amp, powered subwoofer, or powered speakers. Eight Linear-Filtered outlets for streamers, DACs, CD players, preamps, phono stages, and TVs. Each bank is engineered for the kind of gear plugged into it.\u003c\/p\u003e\n\u003ch3\u003eNon-Sacrificial Surge Protection\u003c\/h3\u003e\n\u003cp\u003eMost surge protectors are “sacrificial” — they work once. After a big surge, the parts inside are used up and the unit stops protecting your gear, even though it still passes power.\u003c\/p\u003e\n\u003cp\u003eThe 707 doesn’t work that way. It’s rated to withstand repeated 6,000V \/ 3,000A surges — the most that can pass through a home’s electrical panel — without wearing out.\u003c\/p\u003e\n\u003cp\u003eExtreme Voltage Shutdown adds a second safety layer. If incoming voltage rises above 140VAC, the unit shuts down, then resets when power is safe again.\u003c\/p\u003e\n\u003ch3\u003eA Proper AudioQuest Cable in the Box\u003c\/h3\u003e\n\u003cp\u003eAnd crucially at this price point: the 707 ships with a proper AudioQuest PQ-715 power cable already included.

AudioQuest states the 707 reduces AC noise, keeps current flowing to amps, and protects your gear from surges.\u003c\/p\u003e\n\u003cp\u003eThe 707 has won Headfonia’s Best of Year 2024 and the iEar HiFi Award for Best Accessory, plus positive reviews from CE Pro and Alpha Audio. Results vary with how dirty your AC is and how detailed your system sounds — but the 707 has a very strong track record at this price.\u003c\/p\u003e\n\u003ch3\u003eWill a power conditioner limit the dynamics of my amplifier?\u003c\/h3\u003e\n\u003cp\u003eThis is a fair worry. Many conditioners do choke the current an amplifier can draw on big musical peaks. The PowerQuest 707 is designed to avoid that.\u003c\/p\u003e\n\u003cp\u003eIts four High-Current outlets use Transient Power Correction — a low-impedance circuit with a 45-amp peak reservoir. Plug your amp, integrated amp, or powered subwoofer into one of these four outlets, and you should not lose dynamics. Same core principle from AudioQuest’s much pricier Niagara line.\u003c\/p\u003e\n\u003ch3\u003eWhich outlets do I plug my amp into, and which are for my source gear?\u003c\/h3\u003e\n\u003cp\u003ePlug power amplifiers, integrated amps, powered subwoofers, and powered speakers into the four High-Current outlets (clearly labeled on the rear panel). Plug streamers, DACs, CD players, preamps, phono stages, and TVs into the eight Linear-Filtered outlets — they get the heavier filtering for the quietest background. AudioQuest clearly labels which outlets are which.\u003c\/p\u003e\n\u003ch3\u003eDo I need this if I already have a good surge protector?\u003c\/h3\u003e\n\u003cp\u003eSurge protection and power conditioning are two different jobs. A basic surge strip blocks voltage spikes but does nothing for AC noise — and most use throwaway MOV parts that wear out with every surge.\u003c\/p\u003e\n\u003cp\u003eThe 707 does both at a high level: Non-Sacrificial Surge Protection that withstands repeated 6,000V \/ 3,000A surges, plus dual 30 kHz – 1 GHz filters and 45-amp Transient Power Correction. None of that is in any surge strip.\u003c\/p\u003e\n\u003ch3\u003eDo I need to buy a separate power cable?\u003c\/h3\u003e\n\u003cp\u003eNo — the 707 ships with a 2-meter AudioQuest PQ-715 detachable power cable already in the box. It uses AudioQuest’s Semi-Solid Long-Grain Copper conductors and is a genuinely good cable, ready to use.\u003c\/p\u003e\n\u003cp\u003eMany conditioners in this price range don’t include any cable at all, so this is real value built in. If you later want to upgrade, the NRG-Z3 is the natural next step — Headfonia’s reviewer reported better resolution and a wider soundstage after swapping in the NRG-Z3.\u003c\/p\u003e\n\u003ch3\u003eIs the surge protection guaranteed? What happens after a surge?\u003c\/h3\u003e\n\u003cp\u003eAudioQuest’s Non-Sacrificial Surge Protection is rated to withstand repeated 6,000V \/ 3,000A surges — the most that can pass through a home’s electrical panel — without needing to be replaced. There’s no joule threshold after which protection stops.\u003c\/p\u003e\n\u003cp\u003eExtreme Voltage Shutdown adds a second layer by shutting down the unit if incoming voltage exceeds 140VAC. The PowerQuest 707 itself comes with a 5-year warranty.\u003c\/p\u003e\n\u003ch3\u003eHow does the PowerQuest 707 compare to the 909 or the Niagara 1200?\u003c\/h3\u003e\n\u003cp\u003eThe PowerQuest 909 is the new flagship of the PowerQuest line. It uses the same Transient Power Correction setup but at 20 amps of capacity instead of 15, with a heavier-duty PQ-920 cable included. Pick the 909 if you have a 20A circuit (or plan to install one) and are running high-current amps.\u003c\/p\u003e\n\u003cp\u003eThe 707 is the right choice if you’re running a standard 15A circuit, want the same core engineering, and want a more affordable price.\u003c\/p\u003e\n\u003cp\u003eVersus the Niagara 1200 (a similar price), the 707 has more outlets (12 vs. 7), includes Transient Power Correction (the 1200 does not), and ships with a cable — making it a strong value at this price.\u003c\/p\u003e\n\u003ch3\u003eDoes this work on a standard 15-amp circuit?\u003c\/h3\u003e\n\u003cp\u003eYes. The PowerQuest 707 is rated for 15A operation and uses a standard IEC C13 input, plugging into a normal US wall outlet via the included PQ-715 cable. You do not need a dedicated 20A circuit.\u003c\/p\u003e\n\u003cp\u003eThis is one of the 707’s core advantages over the 909 (a 20A unit).

LED drivers, switch-mode wall-warts on every smart device, Wi-Fi access points, cellular base stations, neighbors’ HVAC systems, electric cars charging next door — all of it dumps electrical noise onto the same shared utility transformer that feeds your listening room. That noise rides the line into your DAC, preamp, amplifier, and streamer, where it shows up in the listening chair as a slightly hazy midrange, less defined low-level detail, and a noise floor that masks the quiet stuff in the music.\u003c\/p\u003e\n\n\u003cp\u003eThe iFi PowerStation is iFi’s response to that problem in a whole-system, eight-outlet form factor. Where most power conditioners use passive filters — chokes, capacitors, and transformers tuned to attenuate noise across a chosen frequency range — the PowerStation does something fundamentally different. It uses iFi’s \u003cstrong\u003eActive Noise Cancellation II\u003c\/strong\u003e circuit to \u003cem\u003eactively generate an inverse copy of the incoming noise\u003c\/em\u003e and sum it back into the line, where the two signals cancel each other. Same principle as noise-cancelling headphones, applied to AC mains.\u003c\/p\u003e\n\n\u003cp\u003eThe practical result, per iFi’s measurements: roughly \u003cstrong\u003e40 dB\u003c\/strong\u003e (more than 100×) of noise reduction across the full audio-relevant frequency range, including the lower frequencies where passive filters struggle. \u003cem\u003eIn our experience, a good power conditioner or low-noise power supply will almost always noticeably improve the sound of any high-end audio system.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch3\u003eWhere the PowerStation Fits in the iFi Lineup\u003c\/h3\u003e\n\u003cp\u003eThe PowerStation is iFi’s \u003cstrong\u003etop-tier whole-system AC product\u003c\/strong\u003e. The brand also sells smaller AC iPurifier modules that plug directly into a wall outlet (or into one of the PowerStation’s outlets) and apply the same active-cancellation technology to a single component. Many PowerStation owners also run AC iPurifiers in two of the eight outlets — typically one in the digital section and one in the analog section — to get extra cleanup right at the source. iFi explicitly designed the PowerStation and AC iPurifier to be additive: each one adds another stage of cancellation, and the two are intended to be used together in serious systems.\u003c\/p\u003e\n\n\u003cp\u003eThe PowerStation does not replace the wall-wart on a streamer or DAC — that’s the job of the iFi iPower Elite (a low-noise DC supply for components with an external power adapter). The PowerStation cleans up the AC feeding everything else: integrated amps, power amps, preamps, turntables, source components with internal AC transformers, and the iPower Elite supplies themselves.\u003c\/p\u003e\n\n\u003c!-- THE TECHNOLOGY INSIDE --\u003e\n\u003ch2\u003eThe Technology Inside the PowerStation\u003c\/h2\u003e\n\n\u003ch3\u003eActive Noise Cancellation II — Active vs Passive, Explained\u003c\/h3\u003e\n\u003cp\u003eMost power conditioners on the market use passive filtering: chokes (inductors), bypass capacitors, and sometimes ferrites tuned to attenuate noise above a chosen frequency. Passive filters work well at higher frequencies — they’re effective in the high-MHz range where switching-supply hash and RF interference live — but they struggle in the lower-frequency range (audio-band and just-above) where some of the most audible noise sits. Building a passive filter that works well at low frequencies requires very large inductors and capacitors, which is why effective passive conditioners tend to be heavy, bulky, and expensive.\u003c\/p\u003e\n\n\u003cp\u003eiFi’s Active Noise Cancellation II works on a different principle. A sensing circuit continuously monitors the noise on the AC line in real time. A second circuit generates an inverse-phase copy of that noise — same shape, opposite sign — and injects it back into the line. The two cancel each other, leaving a quieter signal. This active approach works \u003cem\u003eacross the full frequency range\u003c\/em\u003e, including the lower frequencies where passive filters fall short, and it does it without needing a heavy iron-core inductor in the signal path. Each outlet on the PowerStation also has additional \u003cstrong\u003epassive filtering\u003c\/strong\u003e tuned for the very highest-frequency RF and EMI — Wi-Fi, Bluetooth, cellular — where active cancellation is less efficient. The combination of active and passive filtering is what gets the PowerStation to its \u0026gt;40 dB total noise-reduction figure.\u003c\/p\u003e\n\n\u003ch3\u003eSmart Diagnostics and Intelligent Ground\u003c\/h3\u003e\n\u003cp\u003eA pair of “go\/no-go” indicator LEDs on the PowerStation’s wedge-shaped front section continuously monitor your AC line for two common installation problems: \u003cstrong\u003ereversed polarity\u003c\/strong\u003e and \u003cstrong\u003emissing earth ground\u003c\/strong\u003e. Reversed polarity is more common than people think — it usually means an outlet was wired wrong by the original installer, and it can degrade audio performance and create safety risks. Missing or floating ground shows up as audible buzz or hum at the speakers, and it’s surprisingly common in older homes. The PowerStation tells you both at a glance.\u003c\/p\u003e\n\n\u003cp\u003eIf your listening room turns out to have a missing or ineffective ground, iFi includes a \u003cstrong\u003e4mm banana socket\u003c\/strong\u003e on the front of the unit — you can connect a supplemental earth wire (run to a known good ground point) and the PowerStation will use it. iFi calls this circuit \u003cstrong\u003eIntelligent Ground\u003c\/strong\u003e, because it does not blindly create a ground connection that might form a ground loop with an existing earth in the rest of your system. If your system already has a working ground, the supplemental ground stays out of the way. If it doesn’t, the supplemental ground is what fixes the buzz.\u003c\/p\u003e\n\n\u003ch3\u003eSurge Protection and Over-Voltage Cutout\u003c\/h3\u003e\n\u003cp\u003eThe PowerStation includes \u003cstrong\u003espike and surge protection rated to 30,000 amps at 1,000 V over 10 microseconds\u003c\/strong\u003e — a serious specification, comparable to dedicated whole-house surge protectors. If a major event hits the line (lightning, utility transient, equipment short), the PowerStation cuts power to all eight outlets and waits until conditions are safe before rebooting. If the over-voltage condition persists, the PowerStation stays in protection mode and will not power on, deliberately keeping your equipment safe rather than retrying into a still-faulty line. There’s no MOV that sacrifices itself on a single hit; the protection circuit is non-sacrificial and continues protecting after multiple events.\u003c\/p\u003e\n\n\u003ch3\u003eBuild, Conductors, and Outlet Isolation\u003c\/h3\u003e\n\u003cp\u003eInside the PowerStation’s \u003cstrong\u003edark anodized aluminum chassis\u003c\/strong\u003e, each of the eight outlets sits in its \u003cem\u003eown individually shielded chamber\u003c\/em\u003e, with strategically placed EVA (ethylene vinyl acetate) damping material to keep mechanical vibration from coupling between outlets. This is a real engineering decision, not cosmetic — adjacent outlets in a typical power strip share both their conductive bus and their physical enclosure, which lets noise from a switch-mode supply on one outlet contaminate an analog component on the adjacent outlet. The PowerStation breaks that path.\u003c\/p\u003e\n\n\u003cp\u003eiFi uses \u003cstrong\u003ePurCopper\u003c\/strong\u003e — 99.9999% pure OFHC (Oxygen-Free High-Conductivity) continuous-cast copper — for all the high-current paths inside the unit, including the busbars that carry power between outlets, the conductive contacts of the AC outlets themselves, and the heavy-gauge internal wiring with multi-layered polymer insulation. PurCopper is the same conductor metallurgy used in audiophile cables; using it for the busbars and outlet contacts means the noise reduction the PowerStation delivers isn’t undone by a $0.50 stamped-brass outlet contact on the way out.\u003c\/p\u003e\n\n\u003c!-- OUTLETS \u0026 FEATURES --\u003e\n\u003ch2\u003eOutlets, Layout, and Front-Panel Controls\u003c\/h2\u003e\n\n\u003ch3\u003eOutlet Configuration\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e8 NEMA 5-15 AC outlets, individually isolated in their own EVA-damped chambers, with PurCopper conductive elements throughout.

Plug your audio components into the PowerStation. iFi suggests grouping them by type if you can: digital sources (DAC, streamer, disc player) on one half of the unit, analog gear (preamp, phono, integrated\/power amp) on the other. If you also own one or more iFi \u003cstrong\u003eAC iPurifier\u003c\/strong\u003e modules, the recommended setup is to plug an iPurifier into one of the middle outlets to act as a noise barrier between the digital and analog sections.\u003c\/p\u003e\n\n\u003c!-- HONEST CURRENT-RATING DISCUSSION --\u003e\n\u003ch3\u003eHow Much Gear Can It Power?\u003c\/h3\u003e\n\u003cp\u003eThe PowerStation is rated for \u003cstrong\u003e10 amps maximum total load\u003c\/strong\u003e. In a US 120V installation, that works out to roughly \u003cstrong\u003e1,200 watts\u003c\/strong\u003e of continuous draw across all eight outlets combined. (iFi’s marketing materials sometimes quote “2,500W” — that figure is for 230V markets, where 10A × 230V = 2,300W. In 120V US use, your ceiling is the lower number.)\u003c\/p\u003e\n\n\u003cp\u003eThat 1,200-watt budget is generous for most audiophile systems: a streamer, a DAC, a phono stage, a preamp, and a moderately powered integrated or stereo amplifier will typically draw well under 600W combined at normal listening levels. A home theater rack with a multichannel AV receiver, a 4K display, and a few source components also fits comfortably. Where the PowerStation runs short on headroom is the corner case where you’re trying to power a pair of high-current Class A monoblocks pulling 400+ watts each at idle — that’s not the use case the PowerStation is designed for. For a system in that bracket, an AudioQuest Niagara, Furman Elite-20 PFi, or similar high-current product is a better match. For everything else, the PowerStation is correctly sized.\u003c\/p\u003e\n\n\u003c!-- FAQ --\u003e\n\u003cdiv class=\"product-faq gsbp-ab3b28d\"\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e \u003chr\u003e\n\n\u003ch3\u003eHow does the PowerStation compare to a Furman Elite or AudioQuest Niagara?\u003c\/h3\u003e\n\u003cp\u003eDifferent design philosophy. Furman, AudioQuest, and most other audio power conditioners use \u003cstrong\u003epassive filtering\u003c\/strong\u003e — heavy chokes, large bypass capacitors, and tuned filter banks. iFi’s approach is \u003cstrong\u003eactive\u003c\/strong\u003e: a circuit that continuously generates inverse noise and cancels what’s on the line. Both approaches work; they have different strengths. Active cancellation reaches lower frequencies more efficiently and can deliver substantial noise reduction in a smaller, lighter chassis. Passive filtering pairs more naturally with high-current amplifier outlets and surge-isolation transformer designs (like the Furman IT-Reference series or AudioQuest Niagara 5000). For a streamer\/DAC\/preamp\/integrated-amp system in the 1,200W envelope, the PowerStation is competitive with similarly-priced passive units and offers a more modern technical approach. For very high-current systems, a Furman Elite-20 PFi or AudioQuest Niagara is the right call.\u003c\/p\u003e\n\n\u003ch3\u003eWill it limit my amplifier’s dynamics?\u003c\/h3\u003e\n\u003cp\u003eThe PowerStation does not put a series choke in the signal path the way some “filtered” outlets do. The active cancellation circuit operates in parallel with the signal path, so it doesn’t restrict current flow to your amplifier. That said, the PowerStation is rated for 10A total and shares that current ceiling across all eight outlets. If your amplifier alone can pull 8-9 amps on transient peaks (most amps under 200 watts per channel won’t), you’ll want to think carefully about what else is sharing the unit. For typical audiophile gear, the answer is no — the PowerStation will not noticeably limit dynamics.\u003c\/p\u003e\n\n\u003ch3\u003eWhat about DC offset on my mains? Does this fix amplifier hum from a humming toroidal transformer?\u003c\/h3\u003e\n\u003cp\u003eNo — the PowerStation is not a DC blocker. If your amplifier’s toroidal transformer is mechanically humming (a buzz coming from the chassis itself, separate from anything coming through the speakers), that’s almost certainly DC offset on the AC line, and a DC-blocking device is the correct fix. Audiolab makes a single-component DC Block and a six-outlet DC Block 6 specifically for that problem. The PowerStation cleans up RFI\/EMI noise but does not remove DC offset. If you have both problems — DC-induced transformer hum \u003cem\u003eand\u003c\/em\u003e general AC noise — you can run an Audiolab DC Block in front of the PowerStation, or vice-versa.\u003c\/p\u003e\n\n\u003ch3\u003eWhat’s the warranty?\u003c\/h3\u003e\n\u003cp\u003eiFi backs the PowerStation with a \u003cstrong\u003e12-month limited warranty\u003c\/strong\u003e from date of purchase.

Audio Advisor is an authorized iFi dealer, so your warranty is in place when you buy from us.\u003c\/p\u003e\n\n\u003ch3\u003eWhy does it have a banana socket for ground?\u003c\/h3\u003e\n\u003cp\u003eSome older homes — and many rented apartments and condos — have AC outlets without a working earth ground, even if there’s a third pin in the outlet. A missing ground typically shows up as an audible buzz or hum in the speakers when the system gets quiet between tracks. The 4mm banana socket on the PowerStation’s front lets you connect a supplemental earth wire — usually run to a known good ground point such as a copper cold-water pipe or a dedicated grounding rod.

AC coming into your home carries noise from motors, LED drivers, switching power supplies, wireless routers, HVAC systems, appliance compressors, and every neighbor sharing your utility transformer. That noise rides the power line into your gear, where it masks low-level detail, softens transients, and adds a faint haze to the midrange.\u003c\/p\u003e\n\u003cp\u003eFurman has built AC-power products for professional audio, video, and broadcast use since 1974. The \u003cstrong\u003eElite\u003c\/strong\u003e and \u003cstrong\u003eReference\u003c\/strong\u003e series you're looking at are Furman's home-theater and audiophile lines — the same engineering discipline found in studios and live-sound rigs, packaged for a rack at home. \u003cem\u003eIn our experience, a good power conditioner will almost always noticeably improve the sound of any high-end audio system.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eWhat makes the IT-Reference 20i unique\u003c\/h3\u003e\n\u003cp\u003eThis is Furman's \u003cstrong\u003eflagship\u003c\/strong\u003e home-theater and audiophile power conditioner. Three numbers tell the story of why it exists:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e83 pounds.\u003c\/strong\u003e The IT-Reference 20i weighs nearly twice what the 15-amp IT-Reference weighs. Almost all of that is the custom dual-screen 1:1 isolation transformer, which is built to handle full 20-amp continuous service without saturating and has a dramatically larger, more heavily shielded core than the 15A version's transformer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e8 balanced outlets.\u003c\/strong\u003e Where the IT-Reference 15i has 2 balanced outlets (reserved for sensitive video components) and 5 separately filtered outlets for everything else, the 20i runs \u003cem\u003eeight\u003c\/em\u003e outlets directly off its symmetrical balanced secondary. In practice, every non-amplifier component in your system is fed by the isolation transformer — not just your video gear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e80+ amps of peak PFT charge, 9 amps RMS reserve.\u003c\/strong\u003e The Power Factor Technology bank on the 20i carries roughly twice the RMS reserve and 45% more peak charge current than the PFT bank on the 15i or Elite-20 PFi. The four amplifier outlets can feed a pair of mono power amps and a large powered subwoofer without compressing dynamics, because the PFT reservoir fills in the instantaneous current demand faster than the wall can.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eLiFT filtering bandwidth widens again on the 20i — differential-mode attenuation starts as low as 1 kHz, with greater than 95 dB common-mode rejection on the balanced outlets. This is the cleanest AC Furman builds for a home system. SMP non-sacrificial surge protection, EVS over\/under voltage shutdown, and zero-ground-contamination circuitry all carry forward from the rest of the line — the IT-Reference 20i is Furman's complete Powell-era technology stack, scaled up to reference-system current requirements.\u003c\/p\u003e\n\u003cp\u003eTwo practical notes before you buy. First, the IT-Reference 20i requires a \u003cstrong\u003ededicated 20-amp wall circuit\u003c\/strong\u003e with a NEMA 5-20R outlet. If your audio room is still on a 15A run, you'll want an electrician to pull a dedicated 20A line before the Furman arrives. Second, at 83 pounds and 3U tall, this is not a conditioner you move often. Plan for an equipment rack or a heavy-duty shelf that can take the weight and leave airflow clearance. Backed by Furman's 5-year Reference-series warranty.\u003c\/p\u003e\n\u003c!-- ============ THE POWELL LINEAGE ============ --\u003e\n\u003cp\u003eOne footnote worth mentioning: the engineer who developed Furman's SMP, LiFT, and Power Factor Technology circuits is Garth Powell. Powell spent years refining Furman's AC designs before moving on to lead power-product engineering at AudioQuest, where his work on the Niagara line carries forward many of the same design principles you see in the Elite and Reference conditioners. When you buy a Furman from this era, you're buying into that engineering lineage.\u003c\/p\u003e\n\u003c!-- ============ THE TECHNOLOGY INSIDE ============ --\u003e\n\u003ch2\u003eThe technology inside the IT-Reference 20i\u003c\/h2\u003e\n\u003ch3\u003eSeries Multi-Stage Protection (SMP) — non-sacrificial surge protection\u003c\/h3\u003e\n\u003cp\u003eMost power strips and surge protectors rely on MOVs (metal-oxide varistors) that physically sacrifice themselves when they absorb a large spike. After a big surge, you don't know the protection is gone until your next spike takes your gear with it. \u003cstrong\u003eFurman's SMP circuit is non-sacrificial\u003c\/strong\u003e — it clamps surges without destroying itself, which means one unit keeps protecting after hit after hit. SMP also avoids sending voltage to circuit ground, a common MOV side effect that can actively damage digital components.\u003c\/p\u003e\n\u003ch3\u003eLinear Filtering Technology (LiFT) with flagship bandwidth — noise reduction without choking dynamics\u003c\/h3\u003e\n\u003cp\u003eFurman's \u003cstrong\u003eLiFT\u003c\/strong\u003e circuit is a linear low-pass filter engineered to attenuate AC line noise smoothly across a wide frequency band. On the IT-Reference 20i, the LiFT implementation reaches its widest bandwidth in the Furman line — transverse-mode attenuation starts as low as 1 kHz, with common-mode rejection exceeding 95 dB across the 10 Hz to 50 kHz range on the balanced outlets. This is the cleanest AC Furman builds for a home system, and it's delivered without the current-limiting that some \"filtered\" outlets impose on power amplifiers.\u003c\/p\u003e\n\u003ch3\u003eExtreme Voltage Shutdown (EVS) — protection from sustained over- and under-voltage\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eEVS\u003c\/strong\u003e monitors the incoming line and cuts power to everything downstream if the voltage drifts outside a safe window — too low (below about 85V) or too high (above about 140V). Brownouts and sustained overvoltage events cause more damage to audio gear than most surges do, and EVS is specifically designed to stop them before your amplifier's power supply ever sees them.\u003c\/p\u003e\n\u003ch3\u003eZero ground contamination\u003c\/h3\u003e\n\u003cp\u003eOlder surge-protection designs shunt surge energy to circuit ground, which sounds reasonable until you realize that your preamp, DAC, and digital sources all reference signal to that same ground. \"Contaminated\" ground shows up as hum, noise, and digital hash in the listening chair. Furman's design deliberately avoids this — spikes are clamped without dumping anything to ground.\u003c\/p\u003e\n\u003ch3\u003ePower Factor Technology (PFT) — current reservoir for amplifier peaks\u003c\/h3\u003e\n\u003cp\u003eClass A\/B amplifiers draw current in huge momentary spikes on musical transients — a kick drum, a cymbal crash, a bass note. If the wall and the conditioner can't deliver that current fast enough, the amp's power supply sags, dynamics compress, and bass loses punch. \u003cstrong\u003ePower Factor Technology\u003c\/strong\u003e places a large energy reservoir upstream of the amplifier outlets that provides surplus instantaneous current on demand, while simultaneously lowering the AC input impedance seen by the amp. The amplifier \"sees\" a much stiffer power source than your wall provides on its own.\u003c\/p\u003e\n\u003ch3\u003eDiscrete Symmetrical Power with Dual-Screen Isolation Transformer\u003c\/h3\u003e\n\u003cp\u003eThis is the feature that separates the Reference series from everything below it. A \u003cstrong\u003e1:1 isolation transformer\u003c\/strong\u003e sits between your wall outlet and your audio system, magnetically transferring AC from primary to secondary with no direct electrical connection. A precisely placed center tap on the secondary winding produces \u003cstrong\u003esymmetrical (balanced) AC\u003c\/strong\u003e: two 60V legs, 180° out of phase, referenced to ground. Noise that appears equally on both legs — the dominant form of AC line noise in most homes — is cancelled by common-mode rejection inside the transformer and at each component's power supply. Furman's dual-screen transformer design extends this cancellation across a wider bandwidth than single-screen isolation transformers can reach, and the balanced secondary positively breaks noise-inducing ground loops between interconnected components.\u003c\/p\u003e\n\u003c!-- ============ OUTLETS \u0026 FEATURES ============ --\u003e\n\u003ch2\u003eOutlets and features\u003c\/h2\u003e\n\u003ch3\u003eOutlet configuration\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e8 Discrete Symmetrically Balanced outlets, fed by the 1:1 dual-screen isolation transformer — intended for video components, front-end sources, and processors.\u003c\/li\u003e\n\u003cli\u003e4 Power Factor Technology amplifier outlets with 9 amps RMS reserve and over 80 amps peak charge.\u003c\/li\u003e\n\u003cli\u003eTotal 12 outlets across isolated banks.\u003c\/li\u003e\n\u003cli\u003eRequires a dedicated 20-amp wall circuit (NEMA 5-20R outlet) and matching 20A power cord.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFront-panel controls and displays\u003c\/h3\u003e\n\u003cp\u003ePower switch only — Reference-series front panel is deliberately minimal.

Modern AC power is noisier than it has ever been, and that noise ends up in your listening chair as reduced detail and a flatter soundstage. The longer answer is in the \"Why Furman\" section above — the engineering case for AC conditioning is straightforward once you understand what's riding on the line. \u003cem\u003eIn our experience, a good power conditioner will almost always noticeably improve the sound of any high-end audio system.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eWill a conditioner limit the current my amplifier needs?\u003c\/h3\u003e\n\u003cp\u003eIt can, if the conditioner is badly designed. Cheap \"filtered\" power strips use series chokes that do restrict current — which is why audiophiles rightly worry about plugging big amps into them. Furman's LiFT filter is engineered specifically to avoid that trade-off, and the PFi and IT-Reference models go further by adding a dedicated high-current amplifier bank with Power Factor Technology that actively supplies surplus current on musical peaks. In practice, a well-designed Furman improves amp dynamics rather than limiting them.\u003c\/p\u003e\n\u003ch3\u003eWhat is Power Factor Technology actually doing?\u003c\/h3\u003e\n\u003cp\u003eYour power amplifier draws current in large instantaneous bursts on musical transients — not a steady draw. Wall wiring has real impedance, and when the amp calls for 30+ amps in a millisecond, the wall simply can't deliver that fast. Power Factor Technology places a large energy reservoir upstream of the amplifier outlets, sized specifically to fill in those instantaneous peaks. The amp \"sees\" a far stiffer power source than the wall provides on its own. The audible result is tighter bass, faster transients, and less dynamic compression on loud passages.\u003c\/p\u003e\n\u003ch3\u003eWhy an isolation transformer, instead of just a filter?\u003c\/h3\u003e\n\u003cp\u003eA filter attenuates noise but still leaves your gear electrically connected to the wall. An isolation transformer \u003cem\u003ephysically\u003c\/em\u003e separates the input from the output — AC is induced magnetically from the primary winding to the secondary, so your audio system never sees the wall directly. Common-mode noise on the incoming line is largely rejected before it reaches a single component, and ground-borne noise shared with the rest of your house is broken. It's the most aggressive form of AC cleanup in a home system, and it is the reason the IT-Reference series exists as a separate line above the Elite.\u003c\/p\u003e\n\u003ch3\u003eWhat happens to the Furman after a big surge?\u003c\/h3\u003e\n\u003cp\u003eOrdinary surge protectors sacrifice their MOVs on a major hit — after one significant event, the protection is used up even though the unit looks fine and the power LED still glows. Furman's SMP circuit is non-sacrificial; it clamps surges without destroying itself and keeps protecting afterward. Multiple large hits do not void the protection.\u003c\/p\u003e\n\u003ch3\u003eWhich outlets should I use for what?\u003c\/h3\u003e\n\u003cp\u003eOn an IT-Reference conditioner, the Discrete Symmetrically Balanced outlets are tuned for sensitive video and source components — plug displays, projectors, DACs, preamps, and processors there. The Power Factor Technology outlets are specifically for your amplifier(s) and powered subwoofer(s); those are the components that demand high instantaneous current. On the 15i model, the middle linearly filtered bank is fine for anything that doesn't fall into the above two categories.\u003c\/p\u003e\n\u003ch3\u003eWhat power cord should I use?\u003c\/h3\u003e\n\u003cp\u003eYour wall-to-conditioner power cord is the only one that sees raw, unconditioned mains — so this is where a better cable has the biggest audible impact. A high-quality shielded cord rated for the conditioner's input current (15A or 20A depending on model) is a sensible pairing. The captive cord on the Furman is fine out of the box, but aftermarket cords from AudioQuest, Shunyata, or similar can make a meaningful difference once the conditioner is broken in.\u003c\/p\u003e\n\u003ch3\u003eWhat's the warranty?\u003c\/h3\u003e\n\u003cp\u003eFurman backs the Reference series with a 5-year limited warranty — two years longer than the Elite line, reflecting the heavier build and the flagship status of these models.

Plug your gear in, hope you don’t get a lightning strike, replace it every few years when the indicator light goes out. For a desk lamp and a phone charger, that’s plenty. For a $1,500 receiver, a 4K display, a streaming box, and a turntable, it really isn’t.\u003c\/p\u003e\n\n\u003cp\u003eThe PST series is what happens when a company that’s been engineering AC power products for broadcast studios and live-sound rigs since 1974 decides to make a power strip. The technology stack varies by model — the PST-8 and PST-8D bring the full Powell-engineered SMP \/ LiFT \/ EVS protection found in Furman’s higher-end Elite line, while the PST-6 and PST 2+6 use a simpler but still genuinely upgraded MOV-based circuit with RFI\/EMI filtering. Either way, you’re getting better engineering than the commodity surge strip the buyer was likely replacing, in a form factor that fits the same cable run behind the same equipment rack.\u003c\/p\u003e\n\n\u003cp\u003eTwo things every PST shares. First, \u003cstrong\u003ezero ground contamination\u003c\/strong\u003e: a Furman-specific circuit choice that does not shunt surge energy onto your circuit ground (the way most MOV-based strips do), so your DAC, streamer, and other digital gear don’t have garbage on their ground reference. Second, \u003cstrong\u003esignal-line protection\u003c\/strong\u003e: every PST includes coaxial (cable\/satellite) and telephone surge inputs, because lightning that comes in through the cable line will fry a TV just as effectively as lightning that comes through the wall. \u003cem\u003eIn our experience, a good power conditioner or low-noise power supply will almost always noticeably improve the sound of any high-end audio system\u003c\/em\u003e, and the same engineering principles that make Furman’s higher-end conditioners audible also drive the design of their power strips.\u003c\/p\u003e\n\n\u003ch3\u003eWhat Makes the PST 2+6 the Right Pick\u003c\/h3\u003e\n\u003cp\u003eThe PST 2+6 is positioned as \u003cstrong\u003eFurman’s most affordable entry point\u003c\/strong\u003e — designed for someone who wants real Furman protection engineering on a TV\/streamer\/receiver setup, a desktop computer, or a home-office workstation, without stepping up to the price of a metal-chassis model. Three things that make it the right choice for that buyer:\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFront-panel diagnostics.\u003c\/strong\u003e Two indicator LEDs on the chassis — one labeled “Protection OK” (the surge circuit is healthy) and one labeled “Ground” (your wall outlet is wired correctly with a working earth ground). When one of those LEDs goes dark, you know there’s a problem and you can act on it. Most surge strips give you a single power LED that tells you nothing about whether protection is still intact.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAudible surge alarm.\u003c\/strong\u003e Pair the LED diagnostics with a beeper that fires when a surge takes out the protection circuit. You’ll hear it the moment it happens, not next month when you finally notice the dark LED. Useful for protecting valuable gear in a workspace where the strip might be tucked behind a hutch and out of sight.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe 2+6 outlet layout.\u003c\/strong\u003e The original “2+6” naming refers to the original split (2 wall-wart-spaced outlets + 6 standard). The current production unit is similar in concept — outlets spaced widely enough to accommodate the bulky wall-wart power supplies that come with audio gear, video doorbells, charging hubs, and similar devices, without those wall-warts blocking adjacent outlets. Most commodity strips force you to skip outlets when you have a few wall-warts; the PST 2+6 doesn’t.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eThe trade-off is the chassis. Where the PST-6, PST-8, and PST-8D step up to aluminum construction, the PST 2+6 uses plastic — same general approach as most surge strips in this price range. If structural rigidity and EMI shielding matter for your install, the metal-chassis models are the upgrade path. If you want the maximum Furman protection engineering for the lowest price, the PST 2+6 is the answer.\u003c\/p\u003e\n\n\u003c!-- POWELL LINEAGE --\u003e\n\u003cp\u003eOne footnote worth mentioning: the engineer who developed Furman’s SMP, LiFT, and broader power-product circuit design is Garth Powell. Powell spent years refining Furman’s AC products before moving on to lead power-product engineering at AudioQuest, where his work on the Niagara line carries forward many of the same design principles. When you buy a Furman from this era, you’re buying into that engineering lineage — even at the entry level.\u003c\/p\u003e\n\n\u003c!-- THE TECHNOLOGY INSIDE --\u003e\n\u003ch2\u003eThe Technology Inside the PST 2+6\u003c\/h2\u003e\n\n\u003ch3\u003eFused MOV Surge Protection\u003c\/h3\u003e\n\u003cp\u003eThe PST series Tier-1 products use a \u003cstrong\u003efused metal-oxide-varistor (MOV) shunt circuit\u003c\/strong\u003e, Line-Neutral. When a surge hits the line, the MOV briefly clamps the over-voltage and shunts it through a fuse. The fuse is the smart part — most cheap surge strips have an MOV that simply degrades and silently fails after enough hits, leaving you “protected” by a dead component while the indicator light still glows green. Furman’s fused design gives a definite end-of-life signal: when the fuse blows, you know the protection is gone.\u003c\/p\u003e\n\n\u003cp\u003eThis is genuinely better than a generic surge strip, but it’s worth being clear about what it is and isn’t. It’s not the non-sacrificial SMP circuit found in the Furman Elite series and the PST-8\/PST-8D — those are engineered to keep clamping after multiple large hits without sacrificing anything. The Tier-1 PST series is fused-MOV protection done right, paired with the rest of Furman’s circuit design philosophy.\u003c\/p\u003e\n\n\u003ch3\u003eRFI \/ EMI Noise Filtering\u003c\/h3\u003e\n\u003cp\u003eBeyond the surge protection, every PST includes a \u003cstrong\u003epassive RFI\/EMI filter\u003c\/strong\u003e tuned to attenuate AC line noise more than 40 dB across the 150 kHz to 100 MHz band — the frequency range where most of the contamination from switch-mode wall-warts, LED drivers, and household electronics actually lives. That filter is what separates “Furman-quality protection” from a $25 commodity surge strip, and it’s the part you actually hear on a high-resolution audio system.\u003c\/p\u003e\n\n\u003ch3\u003eZero Ground Contamination\u003c\/h3\u003e\n\u003cp\u003eOlder surge-protection designs shunt surge energy to circuit ground, which sounds reasonable until you realize that your DAC, streamer, and other digital sources all reference signal to that same ground. Garbage on the ground rail shows up in the listening chair as hum, hash, and a slightly elevated noise floor. Furman’s circuit design deliberately avoids this — surges are clamped without dumping anything to ground.\u003c\/p\u003e\n\n\u003c!-- BUILD QUALITY --\u003e\n\u003ch3\u003eBuild Quality and Form Factor\u003c\/h3\u003e\n\u003cp\u003eThe PST 2+6 uses a plastic chassis — the same general construction approach as most surge strips in this price range. That keeps the cost down, which is the point at this tier of the line. (The metal-chassis PST-6, PST-8, and PST-8D step up to aluminum construction at a corresponding step-up in price; if structural rigidity and EMI shielding matter for your install, those models are worth the look.)\u003c\/p\u003e\n\n\u003cp\u003eWhat you do get on the PST 2+6 that you don’t get on the PST-6 is \u003cstrong\u003ereal-time diagnostics\u003c\/strong\u003e: front-panel “Protection OK” and “Ground” indicator LEDs let you see at a glance that the surge circuit is healthy and that your wall outlet is wired correctly. There’s also an \u003cstrong\u003eaudible surge alarm\u003c\/strong\u003e — if a hit takes out the protection circuit, you’ll hear about it immediately rather than discovering it on the next big surge.\u003c\/p\u003e\n\n\u003cp\u003eThe captive 8-foot power cord matches what you’d find on the metal-chassis models. It’s a longer cord than most commodity surge strips, which is genuinely useful when the strip needs to reach across a room or down behind a hutch.\u003c\/p\u003e\n\n\u003c!-- FAQ --\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003ch3\u003eHow is this different from a $25 surge strip from an office store?\u003c\/h3\u003e\n\u003cp\u003eThree meaningful ways. (1) \u003cstrong\u003eSurge protection that actually keeps working.\u003c\/strong\u003e Generic strips use sacrificial MOVs that silently degrade after large hits — your indicator light says “protected” while the protection has actually failed. Furman uses fused MOVs on the PST 2+6, designed to fail in a way you can detect — plus an audible alarm and diagnostic LEDs. (2) \u003cstrong\u003eRFI\/EMI filtering.\u003c\/strong\u003e Generic strips do nothing about the noise riding on your AC line; the PST series filters that noise across the audio-sensitive frequency range. (3) \u003cstrong\u003eZero ground contamination.\u003c\/strong\u003e Generic strips shunt surge energy to ground, which can actually \u003cem\u003eadd\u003c\/em\u003e noise to your digital sources.

The 15-amp current rating across all outlets is plenty of headroom for typical home systems. Where you’d run into trouble is plugging a pair of high-current monoblock power amplifiers into a Furman PST and expecting them to deliver full transient performance — that’s not what these are designed for, and you’d want a higher-end conditioner with a Power Factor Technology bank (the Furman Elite-15 PFi or Elite-20 PFi) for that application. For everything else, the PST series is correctly sized.\u003c\/p\u003e\n\n\u003ch3\u003eWhy are the cable and phone connectors on this thing?\u003c\/h3\u003e\n\u003cp\u003eLightning that comes in through your coax cable line or telephone line will fry a TV or modem just as effectively as lightning that comes through the wall outlet.

The electricity coming out of your wall socket isn’t always as clean and stable as you might expect. Modern homes are full of devices — LED lights, phone chargers, Wi-Fi routers, smart-home gadgets — that dump electrical noise back into your wiring. That noise can sneak into your audio components and affect how they sound and how long they last.\u003c\/p\u003e\n\u003cp\u003eA power conditioner cleans up that electricity before it reaches your gear. The Musical Fidelity X-Power does this while also protecting your components from sudden voltage spikes (like those caused by lightning or power-grid fluctuations) and blocking a common problem called DC offset that can make transformers inside your equipment hum or buzz.\u003c\/p\u003e\n\u003ch3\u003eThree Layers Of Protection In One Compact Unit\u003c\/h3\u003e\n\u003cp\u003eWhat makes the X-Power stand out is that it combines three separate functions into a single, affordable device. According to Musical Fidelity, finding all three in one product at this price point is genuinely uncommon. Here’s what each layer does for you:\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSurge \u0026amp; Overvoltage Protection\u003c\/strong\u003e — The X-Power uses a two-stage protection design. One protection circuit sits at the input and another at the output, so your equipment is shielded at both ends. If a voltage spike hits your power line — from a lightning strike, a utility-grid fluctuation, or a sudden load change — the X-Power diverts that excess energy away from your connected gear. Think of it as an insurance policy for your amplifier, DAC, and turntable.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEMI\/RFI Filtering\u003c\/strong\u003e — EMI (electromagnetic interference) and RFI (radio-frequency interference) are types of electrical noise that travel along your power lines and can affect sensitive audio circuits. The X-Power uses a custom-built filter with dual common-mode chokes and specialized capacitors to suppress this interference. According to Musical Fidelity, the filter achieves greater than 60 dB of noise reduction at 100 kHz and more than 80 dB at 1 MHz — numbers that represent very serious noise suppression.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDC Blocking\u003c\/strong\u003e — DC offset is a sneaky problem. It’s a small amount of unwanted direct-current voltage that rides along on your AC power line. Even a tiny bit of DC offset can push the transformer inside an amplifier or CD player into “saturation,” which causes audible mechanical humming and reduces the transformer’s efficiency. The X-Power’s DC blocker uses a carefully designed network of diodes and capacitors to strip out DC components (up to 2V) while letting the AC power pass through cleanly. If you’ve ever heard a faint buzz or hum from your amplifier that doesn’t go away no matter what you do, DC offset could be the culprit — and this is designed to fix it.\u003c\/p\u003e\n\u003ch3\u003eVersatile Enough For Sources And Amplifiers\u003c\/h3\u003e\n\u003cp\u003eThe X-Power is rated at 10A, which means it can handle up to approximately 1,100 watts in 110V regions (like the U.S.). That’s plenty for most audio setups. For source components like CD players, DACs, streamers, and phono stages — which typically draw only 20–40 watts each — you can connect the X-Power to a high-quality, unfiltered power strip and run several sources from one unit.\u003c\/p\u003e\n\u003cp\u003eIt also has enough headroom for integrated amplifiers and power amplifiers. Musical Fidelity recommends connecting one amplifier per X-Power for the best results. For Class AB stereo amplifiers, they suggest it can comfortably handle amps up to around 700 watts. For Class A designs, it’s rated for stereo amps up to roughly 2 × 550W, and for tube amplifiers, up to about 2 × 200W.\u003c\/p\u003e\n\u003cp\u003eOne important tip from Musical Fidelity: they recommend keeping your digital sources (streamers, CD players, DACs) and analog sources (turntables, phono preamps) on separate X-Power units. Mixing digital and analog gear on the same conditioned line can potentially allow interference between the two.\u003c\/p\u003e\n\u003ch3\u003eThe Return Of An Iconic Design\u003c\/h3\u003e\n\u003cp\u003eIf you’re a long-time audio enthusiast, you might recognize the X-Power’s distinctive cylindrical shape. Musical Fidelity’s original X-Series from the late 1990s used this same “X-profile” design, and it became one of the most recognizable shapes in hi-fi. The X-Power revives that heritage with modern engineering inside a one-piece extruded aluminum chassis. Beyond looking great, the aluminum body serves a functional purpose: it provides excellent shielding against electromagnetic interference. A brushed aluminum faceplate on the front completes the look.\u003c\/p\u003e\n\u003cp\u003eAt just 108 × 105 × 274 mm and only 2.29 kg (about 5 lbs), the X-Power is compact enough to sit unobtrusively in a rack or alongside your existing components.\u003c\/p\u003e\n\u003ch3\u003eWho Is This For?\u003c\/h3\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/2714.svg\" alt=\"✔️\" width=\"15\"\u003e You own a quality audio system and want to protect it from power surges and electrical noise without spending a fortune.\u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/2714.svg\" alt=\"✔️\" width=\"15\"\u003e You’ve noticed a faint hum or buzz from your amplifier or power supply and suspect your home’s electrical supply might be the cause.\u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/2714.svg\" alt=\"✔️\" width=\"15\"\u003e You live in an area with unreliable power, frequent storms, or known electrical noise from nearby appliances or industrial equipment.\u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/2714.svg\" alt=\"✔️\" width=\"15\"\u003e You want a single device that handles surge protection, EMI\/RFI filtering, and DC blocking instead of buying three separate products.\u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/2714.svg\" alt=\"✔️\" width=\"15\"\u003e You’re building or expanding a Musical Fidelity X-Series system and want a matching power conditioner.\u003c\/p\u003e\n\u003ch2\u003eWhat’s In The Box\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMusical Fidelity X-Power Power Conditioner\u003c\/li\u003e\n\u003cli\u003eIEC power cable\u003c\/li\u003e\n\u003cli\u003eUser documentation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePairs Well With\u003c\/h2\u003e\n\u003cp\u003eBuilding your system?

Some listeners notice immediately reduced hum and a quieter noise floor. Others may find the benefit is more about long-term equipment protection than a dramatic sonic change. The X-Power is designed first and foremost to provide cleaner, more stable power — which gives your components the best possible environment to perform as they were designed to.\u003c\/p\u003e\n\u003ch3\u003eCan I Plug Multiple Components Into One X-Power?\u003c\/h3\u003e\n\u003cp\u003eYes. The X-Power has a single outlet, but you can connect it to a high-quality, \u003cem\u003eunfiltered\u003c\/em\u003e power strip and then plug multiple source components into that strip. Source devices like DACs, streamers, CD players, and phono preamps typically draw only 20–40 watts each, so the X-Power can comfortably handle six or more at once. Just make sure the power strip doesn’t have its own built-in filtering, which could conflict with the X-Power’s circuitry.\u003c\/p\u003e\n\u003ch3\u003eShould I Use One X-Power For My Whole System, Or Separate Units For Sources And Amplification?\u003c\/h3\u003e\n\u003cp\u003eMusical Fidelity recommends dedicating one X-Power per amplifier and a separate X-Power for your source components. They also suggest keeping digital devices (streamers, CD players, DACs) and analog devices (turntables, phono preamps) on separate conditioned lines. For a typical two-channel setup with one integrated amp and a few sources, two X-Power units would be ideal — one for the amp and one for your sources.\u003c\/p\u003e\n\u003ch3\u003eIs The X-Power Powerful Enough For My Amplifier?\u003c\/h3\u003e\n\u003cp\u003eIn most cases, yes. At 110V (North America), the X-Power can deliver approximately 1,100 watts. Musical Fidelity provides guidelines: it can handle Class AB stereo amps up to around 700W, Class A stereo amps up to 2 × 550W, and tube amps up to 2 × 200W. Keep in mind that Class AB amplifiers draw power proportional to listening level, so in normal use, they draw much less than their peak rating. If you’re unsure about your specific amplifier, give us a call and we’ll help you figure it out.\u003c\/p\u003e\n\u003ch3\u003eHow Does The X-Power Compare To The Musical Fidelity BPC3?\u003c\/h3\u003e\n\u003cp\u003eThe BPC3 is Musical Fidelity’s larger balanced power conditioner. It uses a toroidal transformer with two isolated 300VA output zones and four outlets — designed to power multiple components with complete zone isolation between them. The X-Power is a smaller, simpler, and more affordable single-outlet conditioner with passive filtering (no transformer). If you need multiple isolated outlet zones or have a complex system, the BPC3 is the step up. If you want straightforward, high-quality power conditioning for one amplifier or a group of source components, the X-Power is a great fit.\u003c\/p\u003e\n\u003ch3\u003eWhat Kind Of Power Cable Should I Use With The X-Power?\u003c\/h3\u003e\n\u003cp\u003eThe X-Power uses a standard IEC C14 inlet, which is the same type of detachable power cable used by most audio components. It comes with a power cable in the box, but if you’d like to use a higher-quality aftermarket power cable, any standard IEC cable rated for 10A will work. Check out our \u003ca href=\"https:\/\/www.audioadvisor.com\/shop-power-cables\"\u003epower cable selection\u003c\/a\u003e if you’d like to explore options.\u003c\/p\u003e\n\u003ch3\u003eWhat Outlet Type Does The US Version Have?\u003c\/h3\u003e\n\u003cp\u003eThe US version of the X-Power features a standard NEMA outlet. Musical Fidelity also offers Schuko (European), UK, and Australian outlet variants for other markets. If you need to verify the specific outlet type for your order, please contact us.\u003c\/p\u003e\n\u003ch3\u003eCan The X-Power Help With Transformer Hum?\u003c\/h3\u003e\n\u003cp\u003ePossibly, yes. Transformer hum in amplifiers is often caused by DC offset on the AC power line. Even a small amount of DC voltage can cause a transformer’s core to saturate, resulting in an audible buzz or vibration. The X-Power’s integrated DC blocker is specifically designed to remove DC offset up to 2V, which can reduce or eliminate this type of hum. If your transformer hum is caused by a mechanical issue inside the component itself, a DC blocker won’t solve it — but for DC-offset-related hum, the X-Power is designed to help.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eWhy Audio Advisor?\u003c\/h2\u003e\n\u003cdiv class=\"ec-titlebox-text\"\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/1f3b5.svg\" alt=\"music note emoji\" width=\"20\"\u003e \u003cstrong\u003e40+ Years of Expertise\u003c\/strong\u003e — Since 1981, we’ve helped over a million music lovers find the right gear.\u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/1f504.svg\" alt=\"repeat emoji\" width=\"20\"\u003e \u003cstrong\u003e60-Day Money-Back Guarantee\u003c\/strong\u003e — Take your time.

It was built for light bulbs and electric motors. It was never built for the audio and video gear we use today.\u003c\/p\u003e\n\u003cp\u003eModern homes are full of noise on the AC line. WiFi, cell signals, dimmer switches, LED bulbs, and computer power supplies all add electrical noise — and so do your neighbors’ homes.\u003c\/p\u003e\n\u003cp\u003eAudioQuest has measured what this does. Up to a third of a high-resolution audio signal can be lost or covered up by AC noise before it ever reaches your speakers. Once that detail is gone, no other piece of gear can bring it back.\u003c\/p\u003e\n\u003cp\u003eA power conditioner sits between the wall and your equipment. It filters out the noise, gives your amp the current it needs on big musical peaks, and protects your gear from voltage spikes and surges.\u003c\/p\u003e\n\u003cp\u003eIn our experience, a good power conditioner will almost always noticeably improve the sound of any high-end audio system. The Niagara 5000 is a true flagship conditioner. It’s built for listeners with top-end systems who want their power handled at the same level as the rest of their gear.\u003c\/p\u003e\n\u003ch3\u003eWhat Makes the Niagara 5000 Notable?\u003c\/h3\u003e\n\u003cp\u003eThe Niagara 5000 was designed by Garth Powell, AudioQuest’s Senior Director of Engineering, and it sits just below the flagship Niagara 7000 in the lineup. Compared to the smaller Niagara 3000, the 5000 steps up in nearly every meaningful way — more outlets, more current capacity, deeper filtering, and a much bigger transient current reserve.\u003c\/p\u003e\n\u003ch3\u003eLow-Z Power Noise-Dissipation\u003c\/h3\u003e\n\u003cp\u003e“Low-Z” means low impedance — power flows through freely without being choked. Some conditioners clean up the noise but rob your amp of the dynamic current it needs for big musical peaks. Low-Z filters noise out of the power without limiting current, so your amp still gets everything it needs.\u003c\/p\u003e\n\u003ch3\u003ePatented Ground Noise-Dissipation\u003c\/h3\u003e\n\u003cp\u003eYour home’s electrical ground is supposed to be a clean reference for every component in your system. In reality, it carries a lot of noise picked up from the wiring in your walls. AudioQuest’s Ground Noise-Dissipation drains that noise away before it reaches your gear, so every component has a quieter, cleaner starting point.\u003c\/p\u003e\n\u003ch3\u003eTransient Power Correction — 90 Amps Peak\u003c\/h3\u003e\n\u003cp\u003ePower amps need sudden, big gulps of current on musical peaks — drum hits, orchestral crescendos, deep bass lines. Most power conditioners get in the way, and the music loses its punch.\u003c\/p\u003e\n\u003cp\u003eThe Niagara 5000’s high-current outlets store a reservoir of over 90 amps peak — roughly 35 amps more than the Niagara 3000 delivers. Even the hungriest amplifier has instant access to current the moment the music calls for it.\u003c\/p\u003e\n\u003ch3\u003eSix Banks of Noise Dissipation\u003c\/h3\u003e\n\u003cp\u003eThe Niagara 5000 spreads its noise reduction across 6 separate banks with over 23 octaves of ultra-linear filtering. Common-mode noise dissipation exceeds 30 dB across the 20 kHz to 100 MHz band.\u003c\/p\u003e\n\u003cp\u003eWhat this means: quieter backgrounds, more resolution, and consistent performance across the full audio and RF spectrum — not just a narrow sweet spot.\u003c\/p\u003e\n\u003ch3\u003eNon-Sacrificial Surge Protection\u003c\/h3\u003e\n\u003cp\u003eMost surge protectors are “sacrificial” — they work once. After a big surge, the parts inside are used up and the unit stops protecting your gear, even though it still passes power.\u003c\/p\u003e\n\u003cp\u003eThe Niagara 5000 doesn’t work that way. It’s rated to withstand repeated 6,000V \/ 3,000A surges — the most that can pass through a building’s electrical panel — without wearing out.\u003c\/p\u003e\n\u003cp\u003eExtreme Voltage Shutdown adds a second safety layer.

AudioQuest states the Niagara 5000 reduces noise, keeps current flowing to amplifiers, and protects your gear from surges.\u003c\/p\u003e\n\u003cp\u003eProfessional reviewers — including Kalman Rubinson at Stereophile, a longtime skeptic of power conditioning — have described meaningful improvements after installing a Niagara. Results vary with how dirty your AC is and how detailed your system sounds, but at the reference level, the 5000 is designed to make a clear difference.\u003c\/p\u003e\n\u003ch3\u003eWill a power conditioner limit the dynamics of my amplifier?\u003c\/h3\u003e\n\u003cp\u003eThis is a fair worry. Many conditioners do choke the current an amplifier can draw on big musical peaks. The Niagara 5000 is designed to avoid that.\u003c\/p\u003e\n\u003cp\u003eIts four High-Current outlets use Transient Power Correction — a low-impedance circuit with a reservoir of over 90 amps peak. Plug your amp, integrated amp, or powered subwoofer into one of these four outlets, and you should not lose dynamics. That 90-amp reserve is roughly 35 amps more than the Niagara 3000 offers.\u003c\/p\u003e\n\u003ch3\u003eWhich outlets do I plug my amp into, and which are for my source gear?\u003c\/h3\u003e\n\u003cp\u003ePlug power amplifiers, integrated amps, powered subwoofers, and powered speakers into one of the four High-Current outlets (arranged in two Low-Z banks, labeled “1” and “2” on the rear panel). Plug streamers, DACs, CD players, preamps, phono stages, and TVs into the eight Source outlets (heavier Level-X filtering, quietest background). AudioQuest clearly labels which outlets are which.\u003c\/p\u003e\n\u003ch3\u003eDo I need this if I already have a good surge protector?\u003c\/h3\u003e\n\u003cp\u003eSurge protection and power conditioning are two different jobs. A basic surge strip blocks voltage spikes but does nothing for AC noise — and most use throwaway MOV parts that wear out with every surge.\u003c\/p\u003e\n\u003cp\u003eThe Niagara 5000 does both at a reference level: Non-Sacrificial Surge Protection that withstands repeated 6,000V \/ 3,000A surges, plus six banks of Ground Noise-Dissipation, 23+ octaves of linear filtering, and 90-amp Transient Power Correction. None of that is in any surge strip.\u003c\/p\u003e\n\u003ch3\u003eWhat power cable should I use to plug this into the wall?\u003c\/h3\u003e\n\u003cp\u003eThe Niagara 5000 uses a 20A C19 input and doesn’t include its main AC cable. At this level, AudioQuest’s flagship Storm Series is the logical match — Thunder 20A 1m ($1,195) as the starting point, or Tornado 20A ($1,995 for 2m, a Stereophile 2025 Recommended Component) as the step up.\u003c\/p\u003e\n\u003cp\u003eSee our “Pairs Well With” section above, or call us at \u003ca href=\"tel:8009420220\"\u003e800-942-0220\u003c\/a\u003e and we’ll help you pick.\u003c\/p\u003e\n\u003ch3\u003eIs the surge protection guaranteed? What happens after a surge?\u003c\/h3\u003e\n\u003cp\u003eAudioQuest’s Non-Sacrificial Surge Protection is rated to withstand repeated 6,000V \/ 3,000A surges — the most that can pass through a building’s electrical panel — without needing to be replaced. There’s no joule threshold after which protection stops.\u003c\/p\u003e\n\u003cp\u003eExtreme Voltage Shutdown adds a second safety layer. The main relay opens in under a quarter second if incoming voltage exceeds 140VAC.\u003c\/p\u003e\n\u003cp\u003eThe Niagara 5000 itself comes with a 3-year warranty out of the box (5 years with free registration). Note: there’s no separate connected-equipment warranty — coverage is for the Niagara itself, not your downstream gear.\u003c\/p\u003e\n\u003ch3\u003eHow does the Niagara 5000 compare to the Niagara 3000 or the Niagara 7000?\u003c\/h3\u003e\n\u003cp\u003eThe 5000 sits between the two. Compared to the Niagara 3000, the 5000 has roughly twice the capacity: 20A vs. 15A, 12 outlets vs. 7, 90A vs. 55A peak transient current, and 6 vs. 3 noise-dissipation banks.\u003c\/p\u003e\n\u003cp\u003eCompared to the Niagara 7000, the 5000 gives up the Dielectric-Biased AC isolation transformers on the source outlets — the 7000’s flagship feature and a step up in noise performance on source components.\u003c\/p\u003e\n\u003cp\u003eIf you want the absolute best, step up to the 7000. If you’re running great gear and want near-flagship performance at less than half the price, the 5000 is the sweet spot.\u003c\/p\u003e\n\u003ch3\u003eDo I need a 20-amp wall outlet?\u003c\/h3\u003e\n\u003cp\u003eThe Niagara 5000 is rated for 20A continuous and uses a 20A C19 input. If your wall outlet is a standard 15A, the unit will still operate — but you won’t get the full 20A of headroom it offers, and you may be limiting a high-current amp plugged into it.\u003c\/p\u003e\n\u003cp\u003eIf you have one or more high-current amps, a dedicated 20A circuit is worth considering. An electrician can do this in most homes.

In practice, it rarely is. Most modern household appliances draw current \u003cem\u003easymmetrically\u003c\/em\u003e: dimmer switches, hair dryers, some LED drivers, cheap switch-mode power supplies, and half-wave-rectified devices pull harder on one half of the AC cycle than the other. The result is a small but measurable \u003cstrong\u003eDC offset\u003c\/strong\u003e riding on top of your AC — typically less than 500 millivolts, but more than enough to cause real audible problems.\u003c\/p\u003e\n\u003cp\u003eHere is why that small DC offset matters. Your amplifier almost certainly uses a \u003cstrong\u003etoroidal power transformer\u003c\/strong\u003e. Toroidals are prized in audio because they have very low stray magnetic fields, they run efficiently, and they don't radiate noise into nearby circuits. But toroidals are also famously sensitive to DC on the line. Even a few hundred millivolts of DC offset can push the transformer's magnetic core toward saturation — and a saturated toroidal \u003cem\u003emechanically vibrates\u003c\/em\u003e. You hear that vibration as a buzz or hum coming directly from the amplifier's chassis, separate from anything coming out of your speakers. Efficiency drops, heat goes up, and sonic performance degrades in ways that are harder to measure but easy to hear: softer dynamics, a slight haze over the midrange, less precise imaging.\u003c\/p\u003e\n\u003cp\u003eThis is not a hypothetical problem. If you own a big Class A\/B integrated amp or a pair of power amps with serious toroidals in them and you have ever noticed them humming more in one house than another, or worse at certain times of day, you have almost certainly been listening to DC on the mains.\u003c\/p\u003e\n\u003ch3\u003eWhat the Audiolab DC Block does about it\u003c\/h3\u003e\n\u003cp\u003eThe DC Block is a simple, purpose-built device that sits between your wall outlet and your amplifier (or your whole rack, for the DC Block 6) and \u003cstrong\u003eremoves the DC offset from the AC line\u003c\/strong\u003e. It rebalances the waveform so the positive and negative halves are symmetrical again. With the DC gone, your toroidal transformer stops saturating, the mechanical hum drops away, and the amp's power supply returns to operating efficiently.\u003c\/p\u003e\n\u003cp\u003eThe DC Block also includes a \u003cstrong\u003ehigh-performance audio-class filter\u003c\/strong\u003e that attenuates RFI\/EMI on the AC line — both common-mode noise (airborne interference from Wi-Fi, cell phones, Bluetooth devices) and differential-mode noise (grunge fed back onto the line by switch-mode power supplies, LED drivers, and other modern household loads). That second job is a useful bonus on top of the DC-offset correction. \u003cem\u003eIn our experience, a good power conditioner or DC blocker will almost always noticeably improve the sound of any high-end audio system.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eWhat the DC Block is \u003cem\u003enot\u003c\/em\u003e\n\u003c\/h3\u003e\n\u003cp\u003eWe want to be clear about this because it matters for how you set up your system. The Audiolab DC Block is \u003cstrong\u003enot a surge protector\u003c\/strong\u003e. It has no MOVs, no joule rating, no transient voltage suppression circuit. It will not protect your equipment from a lightning strike or a major line surge. If you need comprehensive surge protection, you want an actual power conditioner (AudioQuest Niagara, Furman Elite, and similar) — or you can run the DC Block downstream of a dedicated surge protector for the best of both worlds.\u003c\/p\u003e\n\u003cp\u003eWhat the DC Block does, it does exceptionally well in its specific lane: it corrects DC offset on the AC line and filters RFI\/EMI. It's a targeted tool for a real, measurable, audible problem. Used where it belongs, it produces a genuinely noticeable improvement. Used as a replacement for proper surge protection, it isn't the right tool.\u003c\/p\u003e\n\u003ch2\u003e\u003c!-- ============ UNIQUE FEATURES ============ --\u003e\u003c\/h2\u003e\n\u003ch3\u003eWhat makes the Audiolab DC Block the right tool\u003c\/h3\u003e\n\u003cp\u003eThe DC Block is a focused, single-purpose device — and that's the point. If you have \u003cstrong\u003eone amplifier that hums mechanically\u003c\/strong\u003e and a normal household rack otherwise, you don't need a $500 six-outlet chassis to fix it. You need to take the DC off the line feeding that one amp. The DC Block does exactly that, in the smallest, simplest, most affordable package Audiolab makes.\u003c\/p\u003e\n\u003cp\u003eThree things make it the right answer for this specific job:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIn-line IEC connection — no rewiring, no rack space needed.\u003c\/strong\u003e The DC Block sits between your wall outlet and your amplifier's existing IEC power cable. Plug its cable into the wall, plug your amp's cable into the DC Block's IEC outlet. That's the install. Five minutes, no tools. The DC Block itself is small enough to hide behind the amp or tuck behind the rack — it doesn't need a shelf of its own.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSized correctly for a single amplifier.\u003c\/strong\u003e The DC Block is rated for a 600VA peak load, which translates to roughly one power amplifier up to 300W total or a stereo amp up to 2×150W. That's generous coverage for most integrated amps, mid-sized stereo amps, and powered subwoofer chassis. For a big monoblock pair, a pair of high-power amps, or your whole system at once, step up to the DC Block 6.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlack or silver finish to match your amp.\u003c\/strong\u003e Audiolab sells the DC Block in both standard audio finishes so it disappears behind or beside the component it's paired with.

For those jobs, look at full power conditioners or move up to the DC Block 6.

That's the signature symptom. Homes with lots of dimmer switches, aging appliances, or shared utility transformers with high-draw neighbors are more likely to show measurable DC offset. If your amp doesn't hum and your system already sounds clean, the improvement will be more subtle — a small lift in dynamics and clarity from the RFI\/EMI filtering alone. If your amp does hum, the DC Block can make that hum disappear entirely, which is one of the more satisfying audible \"a-ha\" moments in this hobby.\u003c\/p\u003e\n\u003ch3\u003eWhich DC Block model should I buy?\u003c\/h3\u003e\n\u003cp\u003eThe short version: if you have \u003cstrong\u003eone big amplifier\u003c\/strong\u003e that hums and a modest rack of other gear, the single DC Block is the surgical, affordable answer — it goes inline with just your amp's power cord and leaves everything else alone. If you want to \u003cstrong\u003etreat your entire system\u003c\/strong\u003e — amp, preamp, streamer, DAC, phono stage, CD player — and replace an ordinary power strip with something purpose-built for audio, the DC Block 6 feeds up to six components from one rack-width chassis with DC removal and mains filtering on every outlet. If you're buying for a reference-level system, or if you plan to expand your rack over time, the DC Block 6 is the better long-term investment.\u003c\/p\u003e\n\u003ch3\u003eHow does the IEC connection work?\u003c\/h3\u003e\n\u003cp\u003eAudiolab designed the DC Block around the standard IEC power-cable connector that most audio components use. Installation is straightforward: unplug your component's captive or detachable power cable from the wall, plug the DC Block's cable into the wall, and plug your component's cable into the DC Block's IEC outlet. No tools, no rewiring, no permanent installation. If your component uses an unusual connector (a figure-8 \/ \"C7\" two-prong connector rather than a standard C13, for example), you'll need the appropriate IEC adapter, which is inexpensive and widely available.\u003c\/p\u003e\n\u003ch3\u003eIsn't this just an expensive ferrite choke?\u003c\/h3\u003e\n\u003cp\u003eNo. A ferrite bead filters high-frequency common-mode noise but does nothing about DC offset. The DC Block uses a dedicated DC-blocking circuit — essentially a pair of back-to-back capacitors with a bleeder network — that passes AC through unchanged while preventing any DC component from reaching your amplifier. The RFI\/EMI filtering is a separate stage that attenuates line-frequency-adjacent noise across a much wider bandwidth than a ferrite alone. If your only problem is high-frequency hash, a $10 ferrite might help a little. If your amplifier is humming because of DC on the line, no amount of ferrite will solve it — you need the DC-blocking circuit.\u003c\/p\u003e\n\u003ch3\u003eWhat's the warranty?\u003c\/h3\u003e\n\u003cp\u003eAudiolab backs the DC Block with a \u003cstrong\u003e3-year parts and labor warranty when you register\u003c\/strong\u003e your product within the registration window, or a 1-year limited warranty without registration.

In practice, it rarely is. Most modern household appliances draw current \u003cem\u003easymmetrically\u003c\/em\u003e: dimmer switches, hair dryers, some LED drivers, cheap switch-mode power supplies, and half-wave-rectified devices pull harder on one half of the AC cycle than the other. The result is a small but measurable \u003cstrong\u003eDC offset\u003c\/strong\u003eriding on top of your AC — typically less than 500 millivolts, but more than enough to cause real audible problems.\u003c\/p\u003e\n\u003cp\u003eHere is why that small DC offset matters. Your amplifier almost certainly uses a \u003cstrong\u003etoroidal power transformer\u003c\/strong\u003e. Toroidals are prized in audio because they have very low stray magnetic fields, they run efficiently, and they don’t radiate noise into nearby circuits. But toroidals are also famously sensitive to DC on the line. Even a few hundred millivolts of DC offset can push the transformer’s magnetic core toward saturation — and a saturated toroidal \u003cem\u003emechanically vibrates\u003c\/em\u003e. You hear that vibration as a buzz or hum coming directly from the amplifier’s chassis, separate from anything coming out of your speakers. Efficiency drops, heat goes up, and sonic performance degrades in ways that are harder to measure but easy to hear: softer dynamics, a slight haze over the midrange, less precise imaging.\u003c\/p\u003e\n\u003cp\u003eThis is not a hypothetical problem. If you own a big Class A\/B integrated amp or a pair of power amps with serious toroidals in them and you have ever noticed them humming more in one house than another, or worse at certain times of day, you have almost certainly been listening to DC on the mains.\u003c\/p\u003e\n\u003ch3\u003eWhat the Audiolab DC Block Does About It\u003c\/h3\u003e\n\u003cp\u003eThe DC Block is a simple, purpose-built device that sits between your wall outlet and your amplifier (or your whole rack, for the DC Block 6) and \u003cstrong\u003eremoves the DC offset from the AC line\u003c\/strong\u003e. It rebalances the waveform so the positive and negative halves are symmetrical again. With the DC gone, your toroidal transformer stops saturating, the mechanical hum drops away, and the amp’s power supply returns to operating efficiently.\u003c\/p\u003e\n\u003cp\u003eThe DC Block also includes a \u003cstrong\u003ehigh-performance audio-class filter\u003c\/strong\u003e that attenuates RFI\/EMI on the AC line — both common-mode noise (airborne interference from Wi-Fi, cell phones, Bluetooth devices) and differential-mode noise (grunge fed back onto the line by switch-mode power supplies, LED drivers, and other modern household loads). That second job is a useful bonus on top of the DC-offset correction. \u003cem\u003eIn our experience, a good power conditioner or DC blocker will almost always noticeably improve the sound of any high-end audio system.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eWhat the DC Block Is \u003cem\u003eNot\u003c\/em\u003e\n\u003c\/h3\u003e\n\u003cp\u003eWe want to be clear about this because it matters for how you set up your system. The Audiolab DC Block is \u003cstrong\u003enot a surge protector\u003c\/strong\u003e. It has no MOVs, no joule rating, no transient voltage suppression circuit. It will not protect your equipment from a lightning strike or a major line surge. If you need comprehensive surge protection, you want an actual power conditioner (AudioQuest Niagara, Furman Elite, and similar) — or you can run the DC Block downstream of a dedicated surge protector for the best of both worlds.\u003c\/p\u003e\n\u003cp\u003eWhat the DC Block does, it does exceptionally well in its specific lane: it corrects DC offset on the AC line and filters RFI\/EMI. It’s a targeted tool for a real, measurable, audible problem. Used where it belongs, it produces a genuinely noticeable improvement. Used as a replacement for proper surge protection, it isn’t the right tool.\u003c\/p\u003e\n\u003ch3\u003eWhat Makes the DC Block 6 the Whole-System Answer\u003c\/h3\u003e\n\u003cp\u003eThe single-chassis Audiolab DC Block fixes the DC-offset problem for one amplifier at a time. That’s perfect if one amp is the thing that hums. But a reference system isn’t just an amplifier — it’s an integrated or preamp-power-amp, a streamer or DAC, a CD transport, a turntable with its own outboard supply, maybe a phono stage, maybe a powered subwoofer. Every one of those components has a power supply that benefits from clean, DC-free AC. Stringing six single DC Blocks behind your rack would work, but it’s expensive, untidy, and impractical.\u003c\/p\u003e\n\u003cp\u003eThe DC Block 6 is the better answer. It does everything the single DC Block does — DC removal, common-mode and differential-mode RFI\/EMI filtering — but in a rack-width chassis with \u003cstrong\u003esix independent IEC outlets\u003c\/strong\u003e, one set of front-panel controls, and a box of IEC cables included so you can wire up the whole rack in an afternoon.\u003c\/p\u003e\n\u003cp\u003eFour things that set the DC Block 6 apart from the single unit:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSix independent outlets, DC blocking and filtering on every one.\u003c\/strong\u003e Every component plugged into the DC Block 6 sees the same clean, DC-free, RFI-filtered AC as if it had its own single DC Block in front of it.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOLED front-panel voltmeter.\u003c\/strong\u003e Shows incoming line voltage on a simplified OLED display.

That’s the signature symptom. If your amp doesn’t hum and your system already sounds clean, the improvement will be more subtle — a small lift in dynamics and clarity from the RFI\/EMI filtering alone. If your amp does hum, the DC Block can make that hum disappear entirely.\u003c\/p\u003e\n\u003ch3\u003eWhich DC Block model should I buy?\u003c\/h3\u003e\n\u003cp\u003eIf you have \u003cstrong\u003eone big amplifier\u003c\/strong\u003e that hums and a modest rack of other gear, the single DC Block is the surgical, affordable answer. If you want to \u003cstrong\u003etreat your entire system\u003c\/strong\u003e and replace an ordinary power strip with something purpose-built for audio, the DC Block 6 feeds up to six components from one rack-width chassis with DC removal and mains filtering on every outlet.\u003c\/p\u003e\n\u003ch3\u003eHow does the IEC connection work?\u003c\/h3\u003e\n\u003cp\u003eInstallation is straightforward: unplug your component’s power cable from the wall, plug the DC Block’s cable into the wall, and plug your component’s cable into the DC Block’s IEC outlet. No tools, no rewiring, no permanent installation.\u003c\/p\u003e\n\u003ch3\u003eIsn’t this just an expensive ferrite choke?\u003c\/h3\u003e\n\u003cp\u003eNo. A ferrite bead filters high-frequency common-mode noise but does nothing about DC offset. The DC Block uses a dedicated DC-blocking circuit — essentially a pair of back-to-back capacitors with a bleeder network — that passes AC through unchanged while preventing any DC component from reaching your amplifier. The RFI\/EMI filtering is a separate stage. If your amplifier is humming because of DC on the line, no amount of ferrite will solve it — you need the DC-blocking circuit.\u003c\/p\u003e\n\u003ch3\u003eWhat’s the warranty?\u003c\/h3\u003e\n\u003cp\u003eAudiolab backs the DC Block with a \u003cstrong\u003e3-year parts and labor warranty when you register\u003c\/strong\u003e your product, or a 1-year limited warranty without registration.

It was built for light bulbs and motors, not for today’s audio and video gear. Modern noise from WiFi, dimmer switches, and LED bulbs makes it worse — yours and your neighbors’.\u003c\/p\u003e\n\u003cp\u003eAudioQuest has measured what this does. Up to a third of a high-resolution audio signal can be lost or covered up by AC noise before it reaches your speakers. Once that detail is gone, it’s gone for good.\u003c\/p\u003e\n\u003cp\u003eIn our experience, a good power conditioner will almost always noticeably improve the sound of any high-end audio system.\u003c\/p\u003e\n\u003cp\u003eThe PowerQuest 2 is AudioQuest’s 6-outlet entry into real power conditioning. It’s a slim unit, easy to install, with a dedicated outlet optimized for 4K and 8K video, Non-Sacrificial Surge Protection, and the same Extreme Voltage Shutdown found on the higher-end PowerQuest rack-mount conditioners.\u003c\/p\u003e\n\u003ch3\u003eDifferential-Mode Noise-Dissipation\u003c\/h3\u003e\n\u003cp\u003eThe PQ-2 provides more than 22 dB of noise reduction across a wide 30 kHz – 1 GHz bandwidth in differential mode.\u003c\/p\u003e\n\u003cp\u003eThe filter is linearized for dynamic line impedance, from 0.05 Ohms (source) to 10–50 Ohm load. That means even filtering across the whole range — not a sharp peak at one frequency that leaves nearby bands open.\u003c\/p\u003e\n\u003ch3\u003eNon-Sacrificial Surge Protection + Extreme Voltage Shutdown\u003c\/h3\u003e\n\u003cp\u003eMost surge protectors are “sacrificial” — they work once. After a big surge, the parts inside are used up and the unit stops protecting your gear, even though it still passes power.\u003c\/p\u003e\n\u003cp\u003eThe PQ-2 doesn’t work that way. It’s rated to withstand repeated 6,000V \/ 3,000A surges — the most that can pass through a home’s electrical panel — without wearing out.\u003c\/p\u003e\n\u003cp\u003eExtreme Voltage Shutdown adds a second layer of safety. If incoming voltage goes above 140VAC, the main relay opens in under a quarter of a second.

One High-Current outlet is engineered for your soundbar, AV receiver, or powered subwoofer. One 4K\/8K Video-Optimized outlet adds extra noise-dissipation technology specifically tuned for high-resolution video components — use it for your TV, projector, or 4K\/8K player.\u003c\/p\u003e\n\u003ch3\u003eDesigned to Hide\u003c\/h3\u003e\n\u003cp\u003eThe PQ-2 has a slim profile and a rugged floor-mounting stand, ideal for mounting behind cabinets.

Powell spent years refining Furman's AC designs before moving on to lead power-product engineering at AudioQuest, where his work on the Niagara line carries forward many of the same design principles you see in the Elite and Reference conditioners. When you buy a Furman from this era, you're buying into that engineering lineage.\u003c\/p\u003e\n\u003c!-- ============ THE TECHNOLOGY INSIDE ============ --\u003e\n\u003ch2\u003eThe technology inside the Elite-20 PFi\u003c\/h2\u003e\n\u003ch3\u003eSeries Multi-Stage Protection (SMP) — non-sacrificial surge protection\u003c\/h3\u003e\n\u003cp\u003eMost power strips and surge protectors rely on MOVs (metal-oxide varistors) that physically sacrifice themselves when they absorb a large spike. After a big surge, you don't know the protection is gone until your next spike takes your gear with it. \u003cstrong\u003eFurman's SMP circuit is non-sacrificial\u003c\/strong\u003e — it clamps surges without destroying itself, which means one unit keeps protecting after hit after hit. SMP also avoids sending voltage to circuit ground, a common MOV side effect that can actively damage digital components.\u003c\/p\u003e\n\u003ch3\u003eLinear Filtering Technology (LiFT) with wider bandwidth — noise reduction without choking dynamics\u003c\/h3\u003e\n\u003cp\u003eFurman's \u003cstrong\u003eLiFT\u003c\/strong\u003e circuit is a linear low-pass filter engineered to attenuate AC line noise smoothly across a wide frequency band, instead of the narrow notch-and-ring curve that typical filter circuits produce. On the Elite-20 PFi, the LiFT implementation starts its differential-mode attenuation curve around 5 kHz — extending the filtering deeper into the audio-adjacent RF range than the 15-amp Elite models. You get cleaner AC without the current-limiting that some \"filtered\" outlets impose on power amplifiers.\u003c\/p\u003e\n\u003ch3\u003eExtreme Voltage Shutdown (EVS) — protection from sustained over- and under-voltage\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eEVS\u003c\/strong\u003e monitors the incoming line and cuts power to everything downstream if the voltage drifts outside a safe window — too low (below about 85V) or too high (above about 140V). Brownouts and sustained overvoltage events cause more damage to audio gear than most surges do, and EVS is specifically designed to stop them before your amplifier's power supply ever sees them.\u003c\/p\u003e\n\u003ch3\u003eZero ground contamination\u003c\/h3\u003e\n\u003cp\u003eOlder surge-protection designs shunt surge energy to circuit ground, which sounds reasonable until you realize that your preamp, DAC, and digital sources all reference signal to that same ground. \"Contaminated\" ground shows up as hum, noise, and digital hash in the listening chair.

Modern AC power is noisier than it has ever been, and that noise ends up in your listening chair as reduced detail and a flatter soundstage. The longer answer is in the \"Why Furman\" section above — the engineering case for AC conditioning is straightforward once you understand what's riding on the line. \u003cem\u003eIn our experience, a good power conditioner will almost always noticeably improve the sound of any high-end audio system.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eWill a conditioner limit the current my amplifier needs?\u003c\/h3\u003e\n\u003cp\u003eIt can, if the conditioner is badly designed. Cheap \"filtered\" power strips use series chokes that do restrict current — which is why audiophiles rightly worry about plugging big amps into them. Furman's LiFT filter is engineered specifically to avoid that trade-off, and the PFi and IT-Reference models go further by adding a dedicated high-current amplifier bank with Power Factor Technology that actively supplies surplus current on musical peaks. In practice, a well-designed Furman improves amp dynamics rather than limiting them.\u003c\/p\u003e\n\u003ch3\u003eWhat is Power Factor Technology actually doing?\u003c\/h3\u003e\n\u003cp\u003eYour power amplifier draws current in large instantaneous bursts on musical transients — not a steady draw. Wall wiring has real impedance, and when the amp calls for 30+ amps in a millisecond, the wall simply can't deliver that fast. Power Factor Technology places a large energy reservoir upstream of the amplifier outlets, sized specifically to fill in those instantaneous peaks. The amp \"sees\" a far stiffer power source than the wall provides on its own. The audible result is tighter bass, faster transients, and less dynamic compression on loud passages.\u003c\/p\u003e\n\u003ch3\u003eWhat happens to the Furman after a big surge?\u003c\/h3\u003e\n\u003cp\u003eOrdinary surge protectors sacrifice their MOVs on a major hit — after one significant event, the protection is used up even though the unit looks fine and the power LED still glows. Furman's SMP circuit is non-sacrificial; it clamps surges without destroying itself and keeps protecting afterward. Multiple large hits do not void the protection.\u003c\/p\u003e\n\u003ch3\u003eWhich outlets should I use for what?\u003c\/h3\u003e\n\u003cp\u003ePlug your power amplifier(s) and any powered subwoofer into the four Power Factor Technology outlets — those are the high-current bank with the energy reservoir behind them. The linearly filtered outlets with ultrasonic filtering are tuned for digital and video components (DAC, streamer, disc player, display). The standard linearly filtered outlets handle everything else — preamp, phono stage, tuner, and similar analog source gear.\u003c\/p\u003e\n\u003ch3\u003eWhat power cord should I use?\u003c\/h3\u003e\n\u003cp\u003eYour wall-to-conditioner power cord is the only one that sees raw, unconditioned mains — so this is where a better cable has the biggest audible impact. A high-quality shielded cord rated for the conditioner's input current (15A or 20A depending on model) is a sensible pairing. The captive cord on the Furman is fine out of the box, but aftermarket cords from AudioQuest, Shunyata, or similar can make a meaningful difference once the conditioner is broken in.\u003c\/p\u003e\n\u003ch3\u003eWhat's the warranty?\u003c\/h3\u003e\n\u003cp\u003eFurman backs the Elite series with a 3-year limited warranty.

That means it cleans and protects the AC power coming from your wall before it reaches your audio and video gear. It is the top model in Furman’s Reference line.\u003c\/p\u003e\n\u003cp\u003eFurman has built power gear for recording studios, film, and broadcast for over 40 years. In those places, power problems are not allowed. The IT-Reference 15i brings that same studio-grade power to your home theater or hi-fi. It has 11 outlets and a 15-amp rating, and it even has a small isolation transformer inside that feeds two special outlets with extra-clean power for video gear.\u003c\/p\u003e\n\u003ch3\u003eWhy It Matters for Your System\u003c\/h3\u003e\n\u003cp\u003eYour gear can only sound and look as good as the power feeding it. Noisy power can add hum, hiss, or a soft, washed-out picture. The IT-Reference 15i is built to clean that up.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDiscrete Symmetrical Power.\u003c\/strong\u003e This is Furman’s special trick for video. Two outlets get balanced, ultra-low-noise power from a built-in isolation transformer. This breaks “ground loops” (a common cause of hum and on-screen noise) so a TV or projector is not polluted by noise from, say, a Blu-ray player.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLiFT (Linear Filtering Technology).\u003c\/strong\u003e Furman’s filtering smooths out AC noise evenly across a wide range. The result is a lower noise floor, so quiet details come through and the picture looks cleaner.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower Factor Technology.\u003c\/strong\u003e The IT-Reference 15i stores a big reserve of current — over 55 amps of peak charge. When your amplifier suddenly needs a lot of power for a big, dynamic moment, that reserve is ready, so the music keeps its impact.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSMP and EVS surge protection.\u003c\/strong\u003e Series Multi-Stage Protection (SMP) guards your gear from spikes and surges without wearing out, and it does not dump noise to your ground line. Extreme Voltage Shutdown (EVS) goes one step further: if the incoming voltage climbs dangerously high, the unit shuts off to protect everything plugged into it.\u003c\/p\u003e\n\u003ch3\u003eWhat Reviewers Say\u003c\/h3\u003e\n\u003cp\u003eReviewers describe the IT-Reference 15i as a serious, well-built piece of gear that quietly does its job.\u003c\/p\u003e\n\u003cdiv class=\"ec-blockquote\"\u003e\n\u003cp\u003eA reviewer at \u003cem\u003eHome Theater Shack\u003c\/em\u003e (Dave, 2012) gave the IT-Reference 15i a 4.5-out-of-5 overall score and said he could “heartily recommend” it.

Plug your gear in, hope you don’t get a lightning strike, replace it every few years when the indicator light goes out. For a desk lamp and a phone charger, that’s plenty. For a $1,500 receiver, a 4K display, a streaming box, and a turntable, it really isn’t.\u003c\/p\u003e\n\n\u003cp\u003eThe PST series is what happens when a company that’s been engineering AC power products for broadcast studios and live-sound rigs since 1974 decides to make a power strip. The technology stack varies by model — the PST-8 and PST-8D bring the full Powell-engineered SMP \/ LiFT \/ EVS protection found in Furman’s higher-end Elite line, while the PST-6 and PST 2+6 use a simpler but still genuinely upgraded MOV-based circuit with RFI\/EMI filtering. Either way, you’re getting better engineering than the commodity surge strip the buyer was likely replacing, in a form factor that fits the same cable run behind the same equipment rack.\u003c\/p\u003e\n\n\u003cp\u003eTwo things every PST shares. First, \u003cstrong\u003ezero ground contamination\u003c\/strong\u003e: a Furman-specific circuit choice that does not shunt surge energy onto your circuit ground (the way most MOV-based strips do), so your DAC, streamer, and other digital gear don’t have garbage on their ground reference. Second, \u003cstrong\u003esignal-line protection\u003c\/strong\u003e: every PST includes coaxial (cable\/satellite) and telephone surge inputs, because lightning that comes in through the cable line will fry a TV just as effectively as lightning that comes through the wall. \u003cem\u003eIn our experience, a good power conditioner or low-noise power supply will almost always noticeably improve the sound of any high-end audio system\u003c\/em\u003e, and the same engineering principles that make Furman’s higher-end conditioners audible also drive the design of their power strips.\u003c\/p\u003e\n\n\u003ch3\u003eWhat Makes the PST-8D the Right Pick\u003c\/h3\u003e\n\u003cp\u003eThe PST-8D is the \u003cstrong\u003etop of the PST line\u003c\/strong\u003e. Everything the PST-8 has — non-sacrificial SMP surge protection, LiFT linear filtering, EVS extreme-voltage shutdown — plus one significant addition: the eight outlets are split into \u003cstrong\u003etwo isolated, separately filtered banks\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eWhy isolation matters in a mixed-gear system: digital components like flat-panel displays, AVRs, streamers, and disc players generate substantial high-frequency switching noise on their power-supply ground. When those components share a single filter bank with your turntable, integrated amp, or preamp, that digital noise can propagate backward through the strip’s shared ground and into the analog gear’s power input, where it shows up as a subtle haze in the listening chair. The PST-8D’s two-bank design \u003cstrong\u003ephysically isolates the two halves\u003c\/strong\u003e with separate filtering, so digital-side noise is confined to the digital side.\u003c\/p\u003e\n\n\u003cp\u003eThe “D” in the name stands for “Digital” — referring to the bank-isolation feature, not to a separate digital filter. Both banks get the full LiFT linear filtering and SMP surge protection; the difference is that they get them \u003cem\u003eindependently\u003c\/em\u003e. In practice:\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOne bank\u003c\/strong\u003e for digital gear: TV, streamer, AVR or processor, Blu-ray or disc player, cable box, gaming console. The kind of equipment that runs switch-mode power supplies and generates RF hash on its ground rail.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe other bank\u003c\/strong\u003e for analog gear: turntable, integrated amp or power amp, preamp, phono stage, tuner. The kind of equipment that’s most sensitive to picking up that hash from neighboring components.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eSame aluminum chassis as the PST-8, same 8-foot captive cord with angled NEMA plug, same SMP \/ LiFT \/ EVS protection circuit. The PST-8D is the right pick for systems where digital and analog gear coexist and you want the best chance of keeping them sonically separate. If your system is purely digital (a home theater rig with no turntable) or purely analog (a vintage stereo with no streamer), the PST-8 with its single filter bank is the simpler choice. If you have both, the PST-8D is the upgrade that the PST line offers.\u003c\/p\u003e\n\n\u003c!-- POWELL LINEAGE --\u003e\n\u003cp\u003eOne footnote worth mentioning: the engineer who developed Furman’s SMP, LiFT, and broader power-product circuit design is Garth Powell. Powell spent years refining Furman’s AC products before moving on to lead power-product engineering at AudioQuest, where his work on the Niagara line carries forward many of the same design principles. When you buy a Furman from this era, you’re buying into that engineering lineage — even at the entry level.\u003c\/p\u003e\n\n\u003c!-- THE TECHNOLOGY INSIDE --\u003e\n\u003ch2\u003eThe Technology Inside the PST-8D\u003c\/h2\u003e\n\n\u003ch3\u003eSeries Multi-Stage Protection (SMP) — Non-Sacrificial Surge Protection\u003c\/h3\u003e\n\u003cp\u003eThis is the centerpiece of the PST-8 and PST-8D. Most power strips and surge protectors rely on MOVs that physically sacrifice themselves when they absorb a large spike — after one big surge, the protection is used up even though the indicator light still glows. \u003cstrong\u003eFurman’s SMP circuit is non-sacrificial\u003c\/strong\u003e: it clamps surges without destroying itself, so one PST keeps protecting after hit after hit. SMP is the same surge-protection technology Furman uses in its higher-end Elite series of power conditioners, packaged here in a power-strip form factor at a fraction of the price.\u003c\/p\u003e\n\n\u003ch3\u003eLinear Filtering Technology (LiFT) — Noise Reduction Without Choking Dynamics\u003c\/h3\u003e\n\u003cp\u003eMost “filtered” surge strips use simple non-linear filters that produce a narrow notch-and-ring response — they reduce some noise, but they also introduce resonant peaking that can actually \u003cem\u003eadd\u003c\/em\u003e noise in places. Furman’s \u003cstrong\u003eLiFT\u003c\/strong\u003e circuit is a linear low-pass filter engineered to attenuate AC line noise smoothly across a wide frequency band: greater than 40 dB from 150 kHz to 100 MHz, and greater than 80 dB across the 100 kHz to 1 GHz range. In practical terms: cleaner AC, no resonant peaking, no current limiting that would squeeze your amplifier’s dynamics.\u003c\/p\u003e\n\n\u003ch3\u003eExtreme Voltage Shutdown (EVS) — Protection from Sustained Over-Voltage\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eEVS\u003c\/strong\u003e monitors the incoming line and cuts power to everything downstream if the voltage drifts above approximately 135 to 137 volts — the threshold where a sustained over-voltage condition (utility transformer fault, miswired generator, neighbor pulling power on a shared circuit) starts to cause cumulative damage to gear. Brownouts and sustained over-voltage events damage more audio equipment than surges do, and EVS is specifically designed to stop them before your amp’s power supply ever sees them.\u003c\/p\u003e\n\n\u003ch3\u003eZero Ground Contamination\u003c\/h3\u003e\n\u003cp\u003eOlder surge-protection designs shunt surge energy to circuit ground, which sounds reasonable until you realize that your DAC, streamer, and other digital sources all reference signal to that same ground. Garbage on the ground rail shows up in the listening chair as hum, hash, and a slightly elevated noise floor. Furman’s circuit design deliberately avoids this — surges are clamped without dumping anything to ground.\u003c\/p\u003e\n\n\u003c!-- BUILD QUALITY --\u003e\n\u003ch3\u003eBuild Quality and the Metal Chassis\u003c\/h3\u003e\n\u003cp\u003eOne thing that sets the PST-6, PST-8, and PST-8D apart from most surge protectors in their price range: the chassis is \u003cstrong\u003ealuminum\u003c\/strong\u003e, not plastic. Walk into any office-supply store and you’ll find a wall of plastic-cased surge strips — flimsy, cheap to mold, prone to creaking when an outlet fits tightly, and offering essentially zero EMI shielding. Furman’s metal chassis brings real benefits: structural rigidity that doesn’t deform under power-cord pull, vibration damping for the internal components, and a continuous metallic enclosure that contributes to RF shielding for the protection and filtering circuitry inside.\u003c\/p\u003e\n\n\u003cp\u003eThe captive 8-foot power cord is also a step above commodity practice — heavier-gauge wire than the typical 16-AWG cord on a $25 strip, with a 36-degree NEMA 5-15 plug (angled away from the wall to make installation cleaner behind furniture). Small things, but the kind of thing you notice when you’re routing a permanent install.\u003c\/p\u003e\n\n\u003c!-- FAQ --\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003ch3\u003eHow is this different from a $25 surge strip from an office store?\u003c\/h3\u003e\n\u003cp\u003eThree meaningful ways. (1) \u003cstrong\u003eSurge protection that actually keeps working.\u003c\/strong\u003e Generic strips use sacrificial MOVs that silently degrade after large hits — your indicator light says “protected” while the protection has actually failed. Furman uses non-sacrificial SMP on the PST-8\/PST-8D, designed to keep protecting after repeated hits. (2) \u003cstrong\u003eRFI\/EMI filtering.\u003c\/strong\u003e Generic strips do nothing about the noise riding on your AC line; the PST series filters that noise across the audio-sensitive frequency range. (3) \u003cstrong\u003eZero ground contamination.\u003c\/strong\u003e Generic strips shunt surge energy to ground, which can actually \u003cem\u003eadd\u003c\/em\u003e noise to your digital sources. Furman’s design avoids that.\u003c\/p\u003e\n\n\u003ch3\u003eWhich PST should I buy?\u003c\/h3\u003e\n\u003cp\u003eQuick guide: \u003cstrong\u003ePST 2+6\u003c\/strong\u003e if you want Furman protection in the most affordable form factor and you value the audible surge alarm and diagnostic LEDs (plastic chassis, 8 outlets including 2-3 spaced for wall-warts). \u003cstrong\u003ePST-6\u003c\/strong\u003e if you want a metal-chassis Furman in a 6-outlet configuration with the same entry-tier protection circuit. \u003cstrong\u003ePST-8\u003c\/strong\u003e if you want the full SMP \/ LiFT \/ EVS technology stack — same protection found in the Elite series, in a power-strip form factor with 8 outlets in one bank. \u003cstrong\u003ePST-8D\u003c\/strong\u003e if you have a system with both digital gear (TV, streamer, AVR) and analog gear (turntable, integrated amp) and you want the two banks isolated from each other to keep digital noise out of the analog chain.\u003c\/p\u003e\n\n\u003ch3\u003eWill this limit my amplifier’s current?\u003c\/h3\u003e\n\u003cp\u003eFor the audio gear most people plug into a Furman power strip — receivers, integrated amps, source components, displays — no. The 15-amp current rating across all outlets is plenty of headroom for typical home systems. Where you’d run into trouble is plugging a pair of high-current monoblock power amplifiers into a Furman PST and expecting them to deliver full transient performance — that’s not what these are designed for, and you’d want a higher-end conditioner with a Power Factor Technology bank (the Furman Elite-15 PFi or Elite-20 PFi) for that application. For everything else, the PST series is correctly sized.\u003c\/p\u003e\n\n\u003ch3\u003eWhy are the cable and phone connectors on this thing?\u003c\/h3\u003e\n\u003cp\u003eLightning that comes in through your coax cable line or telephone line will fry a TV or modem just as effectively as lightning that comes through the wall outlet. The PST series includes \u003cstrong\u003esignal-line surge suppression\u003c\/strong\u003e for one cable\/satellite coax connection and one telephone line — pass-through connectors that surge-protect those signals before they reach your gear. If you don’t have cable TV or a landline, you can simply ignore those connectors. If you do, they’re a useful inclusion that most generic surge strips lack entirely.\u003c\/p\u003e\n\n\u003ch3\u003eWhat’s the warranty?\u003c\/h3\u003e\n\u003cp\u003eFurman backs the PST series with a 1-year limited warranty covering defects in materials and workmanship.

It can guard against catastrophic surges but can’t stop the daily micro-spikes that slowly damage sensitive electronics. Worse, many 3-mode strips send extra energy into your gear’s ground, which can cause damage that builds up over time.\u003c\/p\u003e\n\u003cp\u003eThe G8’s Micro-Spike Technology is built to catch those smaller spikes all the time, while Catastrophic-Surge Protection handles the big strikes. Add RF Noise-Dissipation and you get a far more comprehensive surge protector than a generic power strip.\u003c\/p\u003e\n\u003ch3\u003eIs this a power conditioner like the PowerQuest 303 or 505?\u003c\/h3\u003e\n\u003cp\u003eNo. The G8 is a surge-protector and performance-enhancer strip — a different product category from AudioQuest’s PowerQuest rack-mount conditioners.\u003c\/p\u003e\n\u003cp\u003eThe 303, 505, 707, and 909 use Non-Sacrificial Surge Protection (withstanding repeated 6,000V \/ 3,000A surges) plus Linear Noise-Dissipation filters across the audio and RF bandwidths. They’re built for dedicated two-channel and multichannel home theater systems.\u003c\/p\u003e\n\u003cp\u003eThe G8 is simpler and more affordable, with its own strengths: Micro-Spike Technology, catastrophic surge handling, RF filtering, and a compact form factor.\u003c\/p\u003e\n\u003cp\u003eIf you have a high-end system, step up to a PowerQuest rack-mount conditioner. If you want serious surge protection for a TV, computer, or gaming setup, the G8 is the right product.\u003c\/p\u003e\n\u003ch3\u003eWhat’s the Micro-Spike Technology?\u003c\/h3\u003e\n\u003cp\u003eAudioQuest coined “Micro-Spike” to describe the small, fast power spikes that appliances, HVAC systems, motors, and switching power supplies generate dozens of times per day on a home’s AC line.\u003c\/p\u003e\n\u003cp\u003eThese are too small to trigger a typical surge protector but large enough to slowly damage the modern surface-mount chips inside your gear over time. The G8’s Micro-Spike circuit is built to catch these spikes before they reach your gear.\u003c\/p\u003e\n\u003ch3\u003eWhat’s covered by the warranty?\u003c\/h3\u003e\n\u003cp\u003eThe G8 comes with AudioQuest Assurance — a 5-year limited warranty on the product itself, plus up to $500,000 of connected-equipment coverage in the event of a surge-related equipment failure while properly connected through the G8. Specific coverage terms and claim procedures are documented in the AudioQuest Assurance documentation included in the packaging.\u003c\/p\u003e\n\u003ch3\u003eWhere should I install it?\u003c\/h3\u003e\n\u003cp\u003eThe flat-to-wall 45° plug and slim 1.2” profile make the G8 easy to fit in tight spaces — behind a wall-mounted TV, inside a media cabinet, behind a desk, or anywhere you’d normally struggle to fit a thicker surge strip.\u003c\/p\u003e\n\u003cp\u003ePlug high-demand gear (AV receivers, soundbars, TVs) and sensitive electronics (game consoles, streaming boxes, computers, Apple TV, PS5, Xbox) into the AC outlets.

In practice, it rarely is. Most modern household appliances draw current \u003cem\u003easymmetrically\u003c\/em\u003e: dimmer switches, hair dryers, some LED drivers, cheap switch-mode power supplies, and half-wave-rectified devices pull harder on one half of the AC cycle than the other. The result is a small but measurable \u003cstrong\u003eDC offset\u003c\/strong\u003e riding on top of your AC — typically less than 500 millivolts, but more than enough to cause real audible problems.\u003c\/p\u003e\n\u003cp\u003eHere is why that small DC offset matters. Your amplifier almost certainly uses a \u003cstrong\u003etoroidal power transformer\u003c\/strong\u003e. Toroidals are prized in audio because they have very low stray magnetic fields, they run efficiently, and they don't radiate noise into nearby circuits. But toroidals are also famously sensitive to DC on the line. Even a few hundred millivolts of DC offset can push the transformer's magnetic core toward saturation — and a saturated toroidal \u003cem\u003emechanically vibrates\u003c\/em\u003e. You hear that vibration as a buzz or hum coming directly from the amplifier's chassis, separate from anything coming out of your speakers. Efficiency drops, heat goes up, and sonic performance degrades in ways that are harder to measure but easy to hear: softer dynamics, a slight haze over the midrange, less precise imaging.\u003c\/p\u003e\n\u003cp\u003eThis is not a hypothetical problem. If you own a big Class A\/B integrated amp or a pair of power amps with serious toroidals in them and you have ever noticed them humming more in one house than another, or worse at certain times of day, you have almost certainly been listening to DC on the mains.\u003c\/p\u003e\n\u003ch3\u003eWhat the Audiolab DC Block does about it\u003c\/h3\u003e\n\u003cp\u003eThe DC Block is a simple, purpose-built device that sits between your wall outlet and your amplifier (or your whole rack, for the DC Block 6) and \u003cstrong\u003eremoves the DC offset from the AC line\u003c\/strong\u003e.

If you have \u003cstrong\u003eone amplifier that hums mechanically\u003c\/strong\u003e and a normal household rack otherwise, you don't need a $500 six-outlet chassis to fix it. You need to take the DC off the line feeding that one amp.

Plug its cable into the wall, plug your amp's cable into the DC Block's IEC outlet. That's the install. Five minutes, no tools. The DC Block itself is small enough to hide behind the amp or tuck behind the rack — it doesn't need a shelf of its own.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSized correctly for a single amplifier.\u003c\/strong\u003e The DC Block is rated for a 600VA peak load, which translates to roughly one power amplifier up to 300W total or a stereo amp up to 2×150W. That's generous coverage for most integrated amps, mid-sized stereo amps, and powered subwoofer chassis. For a big monoblock pair, a pair of high-power amps, or your whole system at once, step up to the DC Block 6.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlack or silver finish to match your amp.\u003c\/strong\u003e Audiolab sells the DC Block in both standard audio finishes so it disappears behind or beside the component it's paired with.

That's the signature symptom. Homes with lots of dimmer switches, aging appliances, or shared utility transformers with high-draw neighbors are more likely to show measurable DC offset. If your amp doesn't hum and your system already sounds clean, the improvement will be more subtle — a small lift in dynamics and clarity from the RFI\/EMI filtering alone. If your amp does hum, the DC Block can make that hum disappear entirely, which is one of the more satisfying audible \"a-ha\" moments in this hobby.\u003c\/p\u003e\n\u003ch3\u003eWhich DC Block model should I buy?\u003c\/h3\u003e\n\u003cp\u003eThe short version: if you have \u003cstrong\u003eone big amplifier\u003c\/strong\u003e that hums and a modest rack of other gear, the single DC Block is the surgical, affordable answer — it goes inline with just your amp's power cord and leaves everything else alone. If you want to \u003cstrong\u003etreat your entire system\u003c\/strong\u003e — amp, preamp, streamer, DAC, phono stage, CD player — and replace an ordinary power strip with something purpose-built for audio, the DC Block 6 feeds up to six components from one rack-width chassis with DC removal and mains filtering on every outlet. If you're buying for a reference-level system, or if you plan to expand your rack over time, the DC Block 6 is the better long-term investment.\u003c\/p\u003e\n\u003ch3\u003eHow does the IEC connection work?\u003c\/h3\u003e\n\u003cp\u003eAudiolab designed the DC Block around the standard IEC power-cable connector that most audio components use. Installation is straightforward: unplug your component's captive or detachable power cable from the wall, plug the DC Block's cable into the wall, and plug your component's cable into the DC Block's IEC outlet. No tools, no rewiring, no permanent installation. If your component uses an unusual connector (a figure-8 \/ \"C7\" two-prong connector rather than a standard C13, for example), you'll need the appropriate IEC adapter, which is inexpensive and widely available.\u003c\/p\u003e\n\u003ch3\u003eIsn't this just an expensive ferrite choke?\u003c\/h3\u003e\n\u003cp\u003eNo. A ferrite bead filters high-frequency common-mode noise but does nothing about DC offset. The DC Block uses a dedicated DC-blocking circuit — essentially a pair of back-to-back capacitors with a bleeder network — that passes AC through unchanged while preventing any DC component from reaching your amplifier. The RFI\/EMI filtering is a separate stage that attenuates line-frequency-adjacent noise across a much wider bandwidth than a ferrite alone. If your only problem is high-frequency hash, a $10 ferrite might help a little. If your amplifier is humming because of DC on the line, no amount of ferrite will solve it — you need the DC-blocking circuit.\u003c\/p\u003e\n\u003ch3\u003eWhat's the warranty?\u003c\/h3\u003e\n\u003cp\u003eAudiolab backs the DC Block with a \u003cstrong\u003e3-year parts and labor warranty when you register\u003c\/strong\u003e your product within the registration window, or a 1-year limited warranty without registration.

In practice, it rarely is. Most modern household appliances draw current \u003cem\u003easymmetrically\u003c\/em\u003e: dimmer switches, hair dryers, some LED drivers, cheap switch-mode power supplies, and half-wave-rectified devices pull harder on one half of the AC cycle than the other. The result is a small but measurable \u003cstrong\u003eDC offset\u003c\/strong\u003eriding on top of your AC — typically less than 500 millivolts, but more than enough to cause real audible problems.\u003c\/p\u003e\n\u003cp\u003eHere is why that small DC offset matters. Your amplifier almost certainly uses a \u003cstrong\u003etoroidal power transformer\u003c\/strong\u003e. Toroidals are prized in audio because they have very low stray magnetic fields, they run efficiently, and they don’t radiate noise into nearby circuits. But toroidals are also famously sensitive to DC on the line. Even a few hundred millivolts of DC offset can push the transformer’s magnetic core toward saturation — and a saturated toroidal \u003cem\u003emechanically vibrates\u003c\/em\u003e. You hear that vibration as a buzz or hum coming directly from the amplifier’s chassis, separate from anything coming out of your speakers. Efficiency drops, heat goes up, and sonic performance degrades in ways that are harder to measure but easy to hear: softer dynamics, a slight haze over the midrange, less precise imaging.\u003c\/p\u003e\n\u003cp\u003eThis is not a hypothetical problem. If you own a big Class A\/B integrated amp or a pair of power amps with serious toroidals in them and you have ever noticed them humming more in one house than another, or worse at certain times of day, you have almost certainly been listening to DC on the mains.\u003c\/p\u003e\n\u003ch3\u003eWhat the Audiolab DC Block Does About It\u003c\/h3\u003e\n\u003cp\u003eThe DC Block is a simple, purpose-built device that sits between your wall outlet and your amplifier (or your whole rack, for the DC Block 6) and \u003cstrong\u003eremoves the DC offset from the AC line\u003c\/strong\u003e.

In practice, it rarely is. Most modern household appliances draw current \u003cem\u003easymmetrically\u003c\/em\u003e: dimmer switches, hair dryers, some LED drivers, cheap switch-mode power supplies, and half-wave-rectified devices pull harder on one half of the AC cycle than the other. The result is a small but measurable \u003cstrong\u003eDC offset\u003c\/strong\u003e riding on top of your AC — typically less than 500 millivolts, but more than enough to cause real audible problems.\u003c\/p\u003e\n\u003cp\u003eHere is why that small DC offset matters. Your amplifier almost certainly uses a \u003cstrong\u003etoroidal power transformer\u003c\/strong\u003e. Toroidals are prized in audio because they have very low stray magnetic fields, they run efficiently, and they don't radiate noise into nearby circuits. But toroidals are also famously sensitive to DC on the line. Even a few hundred millivolts of DC offset can push the transformer's magnetic core toward saturation — and a saturated toroidal \u003cem\u003emechanically vibrates\u003c\/em\u003e. You hear that vibration as a buzz or hum coming directly from the amplifier's chassis, separate from anything coming out of your speakers. Efficiency drops, heat goes up, and sonic performance degrades in ways that are harder to measure but easy to hear: softer dynamics, a slight haze over the midrange, less precise imaging.\u003c\/p\u003e\n\u003cp\u003eThis is not a hypothetical problem. If you own a big Class A\/B integrated amp or a pair of power amps with serious toroidals in them and you have ever noticed them humming more in one house than another, or worse at certain times of day, you have almost certainly been listening to DC on the mains.\u003c\/p\u003e\n\u003ch3\u003eWhat the Audiolab DC Block does about it\u003c\/h3\u003e\n\u003cp\u003eThe DC Block is a simple, purpose-built device that sits between your wall outlet and your amplifier (or your whole rack, for the DC Block 6) and \u003cstrong\u003eremoves the DC offset from the AC line\u003c\/strong\u003e. It rebalances the waveform so the positive and negative halves are symmetrical again. With the DC gone, your toroidal transformer stops saturating, the mechanical hum drops away, and the amp's power supply returns to operating efficiently.\u003c\/p\u003e\n\u003cp\u003eThe DC Block also includes a \u003cstrong\u003ehigh-performance audio-class filter\u003c\/strong\u003e that attenuates RFI\/EMI on the AC line — both common-mode noise (airborne interference from Wi-Fi, cell phones, Bluetooth devices) and differential-mode noise (grunge fed back onto the line by switch-mode power supplies, LED drivers, and other modern household loads). That second job is a useful bonus on top of the DC-offset correction. \u003cem\u003eIn our experience, a good power conditioner or DC blocker will almost always noticeably improve the sound of any high-end audio system.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eWhat the DC Block is \u003cem\u003enot\u003c\/em\u003e\n\u003c\/h3\u003e\n\u003cp\u003eWe want to be clear about this because it matters for how you set up your system.

That's the signature symptom. Homes with lots of dimmer switches, aging appliances, or shared utility transformers with high-draw neighbors are more likely to show measurable DC offset. If your amp doesn't hum and your system already sounds clean, the improvement will be more subtle — a small lift in dynamics and clarity from the RFI\/EMI filtering alone. If your amp does hum, the DC Block can make that hum disappear entirely, which is one of the more satisfying audible \"a-ha\" moments in this hobby.\u003c\/p\u003e\n\u003ch3\u003eWhich DC Block model should I buy?\u003c\/h3\u003e\n\u003cp\u003eThe short version: if you have \u003cstrong\u003eone big amplifier\u003c\/strong\u003e that hums and a modest rack of other gear, the single DC Block is the surgical, affordable answer — it goes inline with just your amp's power cord and leaves everything else alone. If you want to \u003cstrong\u003etreat your entire system\u003c\/strong\u003e — amp, preamp, streamer, DAC, phono stage, CD player — and replace an ordinary power strip with something purpose-built for audio, the DC Block 6 feeds up to six components from one rack-width chassis with DC removal and mains filtering on every outlet. If you're buying for a reference-level system, or if you plan to expand your rack over time, the DC Block 6 is the better long-term investment.\u003c\/p\u003e\n\u003ch3\u003eHow does the IEC connection work?\u003c\/h3\u003e\n\u003cp\u003eAudiolab designed the DC Block around the standard IEC power-cable connector that most audio components use. Installation is straightforward: unplug your component's captive or detachable power cable from the wall, plug the DC Block's cable into the wall, and plug your component's cable into the DC Block's IEC outlet. No tools, no rewiring, no permanent installation. If your component uses an unusual connector (a figure-8 \/ \"C7\" two-prong connector rather than a standard C13, for example), you'll need the appropriate IEC adapter, which is inexpensive and widely available.\u003c\/p\u003e\n\u003ch3\u003eIsn't this just an expensive ferrite choke?\u003c\/h3\u003e\n\u003cp\u003eNo. A ferrite bead filters high-frequency common-mode noise but does nothing about DC offset. The DC Block uses a dedicated DC-blocking circuit — essentially a pair of back-to-back capacitors with a bleeder network — that passes AC through unchanged while preventing any DC component from reaching your amplifier. The RFI\/EMI filtering is a separate stage that attenuates line-frequency-adjacent noise across a much wider bandwidth than a ferrite alone. If your only problem is high-frequency hash, a $10 ferrite might help a little.
