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. It’s a 2-meter detachable cable with Semi-Solid Long-Grain Copper conductors — not a generic stock cord.\u003c\/p\u003e\n\u003cp\u003eMany conditioners in this range — including AudioQuest’s own Niagara 1200 — don’t include a cable at all. So you’re adding hundreds of dollars on top just to connect the thing to your wall.\u003c\/p\u003e\n\u003c!-- WHAT WILL YOU HEAR --\u003e\n\u003ch2\u003eWhat the Pros Are Saying\u003c\/h2\u003e\n\u003cdiv class=\"ec-blockquote\"\u003e\n\u003cstrong\u003eCE Pro — Robert Archer | December 2023\u003c\/strong\u003e\u003cbr\u003eIndustry veteran Robert Archer, writing for CE Pro, noted that the PQ-707 had a positive impact both in terms of improved performance and protection. Looking at the performance benefits, the surge protection, and the build quality of the power cables, he wrote that the 707 delivers what shoppers want and expect from AudioQuest.\u003c\/div\u003e\n\u003cdiv class=\"ec-blockquote\"\u003e\n\u003cstrong\u003eHeadfonia — Yagiz | Best of Year 2024\u003c\/strong\u003e\u003cbr\u003eYagiz reviewed the PowerQuest 707 in 2024 and kept the unit in his personal system. He noted that it protects his gear from surges and improves performance noticeably — darker backgrounds, better imaging and resolution, and fewer “smudges” around the music. He also tried replacing the included PQ-715 cable with an AudioQuest NRG-Z3 and reported better resolution and a slightly wider soundstage.\u003c\/div\u003e\n\u003cdiv class=\"ec-blockquote\"\u003e\n\u003cstrong\u003eAlpha Audio — Bench-Test Review | April 2024\u003c\/strong\u003e\u003cbr\u003eThe engineering-focused Dutch publication put the PowerQuest 707 on its test bench with a deliberately noisy switching amp in the system. With the 707 in line, overall noise drops and the impact from the dirty amplifier is reduced. The 707 also earned praise for having a 45-amp transient reserve that smaller PowerQuest models don’t have.\u003c\/div\u003e\n\u003cdiv class=\"ec-blockquote\"\u003e\n\u003cstrong\u003eiEar HiFi Award for Best Accessory (2024)\u003c\/strong\u003e\u003cbr\u003eAt Europe’s iEar HiFi show, the PowerQuest 707 received the show’s Best Accessory award — a juried industry honor across a wide field of high-end audio products.\u003c\/div\u003e\n\u003cp\u003eCommon themes across the professional reviews: lower noise floor, better imaging and dimensionality, no loss of dynamic impact — and, importantly for a power conditioner, meaningful surge protection built in.\u003c\/p\u003e\n\u003c!-- HOW DOES IT CONNECT --\u003e\n\u003ch3\u003eHow Does It Connect to Your System?\u003c\/h3\u003e\n\u003cp\u003eThe back panel has 12 total outlets arranged in two banks, and it matters which outlet you use for what:\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFour High-Current outlets\u003c\/strong\u003e — for your power amplifier, integrated amp, powered subwoofer, or powered speakers.

These get the heaviest filtering for the quietest background.\u003c\/p\u003e\n\u003cp\u003eThe PowerQuest 707 is a rack-friendly 3.5” tall, 17” wide, and 13.4” deep, and weighs just 10.8 lbs — so it slots easily into any rack or sits neatly on a shelf. Rack-mount ears (2-RU) are included in the box.\u003c\/p\u003e\n\u003cp\u003eOne of the 707’s quiet advantages: it ships with its own AudioQuest power cable. The detachable 2-meter PQ-715 cable uses AudioQuest’s Semi-Solid Long-Grain Copper conductors, and it’s a genuinely good cable right out of the box. Plug it into the wall, plug your gear into the 707, and you’re running.\u003c\/p\u003e\n\u003c!-- WHO IS THIS BEST FOR --\u003e\n\u003ch2\u003eWho Is This Product Best For?\u003c\/h2\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 invested meaningfully in your system — a good amp, good speakers, a decent source chain — and you want to hear what the system can actually do when the power stops holding it back.\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 own a power amplifier and you refuse to accept any loss of dynamics from a conditioner.

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). If your system doesn’t draw a lot of current, the 707 gives you everything AudioQuest’s design has to offer on the circuits you already have.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c!-- VIDEO EMBED --\u003e\n\u003ch2\u003eSee It in Action — Garth Powell on AudioQuest Power Conditioners\u003c\/h2\u003e\n\u003cp\u003eAudioQuest’s Senior Director of Engineering, Garth Powell, designed the entire PowerQuest line, including the 707. In this discussion from AudioQuest’s official channel, Garth explains the first principle behind his power-conditioner designs: a power amplifier’s first job is unrestricted current delivery to the loudspeaker, and nothing in the AC chain should impede that transfer of energy.\u003c\/p\u003e\n\u003c!-- WHAT'S IN THE BOX --\u003e\n\u003ch2\u003eWhat’s in the Box\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAudioQuest PowerQuest 707 Power Conditioner\u003c\/li\u003e\n\u003cli\u003eDetachable 2m PQ-715 AudioQuest power cable (Semi-Solid Long-Grain Copper)\u003c\/li\u003e\n\u003cli\u003eFour pre-installed rubber feet\u003c\/li\u003e\n\u003cli\u003eTwo 2-RU rack-mount brackets and mounting hardware\u003c\/li\u003e\n\u003cli\u003eOwner’s manual and warranty documentation\u003c\/li\u003e\n\u003cli\u003e5-year warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!-- WHY AUDIO ADVISOR --\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 — Audio Advisor has served over one million audiophiles since 1981.\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 — Try it in your system.

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 3000 is built for serious two-channel systems. It brings the core of AudioQuest’s flagship technology into a smaller, more affordable package.\u003c\/p\u003e\n\u003ch3\u003eWhat Makes the Niagara 3000 Notable?\u003c\/h3\u003e\n\u003cp\u003eThe Niagara 3000 was designed by Garth Powell, the same engineer who designed the flagship Niagara 5000 and 7000. It brings three key technologies from those higher-priced models into a smaller, rack-mount unit.\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\u003c\/h3\u003e\n\u003cp\u003ePower amplifiers 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 3000’s two high-current outlets store a reservoir of more than 55 amps peak. Your amp has instant access to that current the moment the music calls for 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 Niagara 3000 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 layer of safety. If incoming voltage rises too high, the Niagara 3000 disconnects your equipment, then resets when power is safe again.\u003c\/p\u003e\n\u003c!-- WHAT WILL YOU HEAR --\u003e\n\u003ch2\u003eWhat the Pros Are Saying\u003c\/h2\u003e\n\u003cdiv class=\"ec-blockquote\"\u003e\n\u003cstrong\u003eStereophile — Fred Kaplan | August 2021\u003c\/strong\u003e\u003cbr\u003eFred Kaplan was skeptical going in, since he was already running AudioQuest Hurricane power cords and had recently added solar panels.

AudioQuest states the Niagara 3000 reduces noise, lowers distortion, and keeps current flowing to your amp.\u003c\/p\u003e\n\u003cp\u003eProfessional reviewers — including Fred Kaplan at Stereophile, who bought his review sample — have noted that the noise a Niagara removes is the kind you only realize was there once it’s gone. Results vary depending on how dirty your AC is and how detailed your system sounds.\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 3000 is designed to avoid that.\u003c\/p\u003e\n\u003cp\u003eIts two High-Current outlets use Transient Power Correction — a low-impedance circuit with a reservoir of over 55 amps peak. Plug your amp or powered subwoofer into one of these two outlets, and you should not lose dynamics.\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 two High-Current outlets (backed by Transient Power Correction). Plug streamers, DACs, CD players, preamps, phono stages, and TVs into the five Source outlets (heavier Level-X filtering, quietest background). AudioQuest clearly labels which outlets are which on the rear panel.\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 3000 does both: Non-Sacrificial Surge Protection that withstands repeated 6,000V \/ 3,000A surges, plus Ground Noise-Dissipation, Level-X linear filtering, and 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 3000 doesn’t include its main AC power cable, so this is a real decision. AudioQuest’s own Monsoon is the natural starting point ($499.95 at 1m). The Blizzard is the step up ($845 at 1m) for more resolving systems.\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 Niagara 3000 itself comes with a 3-year warranty out of the box (5 years with free registration at AudioQuest).\u003c\/p\u003e\n\u003ch3\u003eHow does the Niagara 3000 compare to the Niagara 1200 or the Niagara 5000?\u003c\/h3\u003e\n\u003cp\u003eThe Niagara 3000 sits between the two. Compared to the Niagara 1200, the 3000 adds Transient Power Correction (the 55-amp reservoir for amplifiers), one more bank of noise-dissipation circuits, and two more octaves of Level-X linear filtering.\u003c\/p\u003e\n\u003cp\u003eCompared to the Niagara 5000, the 3000 steps down: 15A vs. 20A, 7 outlets vs. 12, 55A vs. 90A peak transient current, and 3 vs. 6 noise-dissipation banks.\u003c\/p\u003e\n\u003cp\u003eIf your amp is highly dynamic or you have a full home theater rack, consider the 5000. If you’re running a focused two-channel system, the 3000 is the sweet spot.\u003c\/p\u003e\n\u003c!-- VIDEO EMBED --\u003e\n\u003ch2\u003eSee It in Action — Designer Garth Powell on the Niagara 3000\u003c\/h2\u003e\n\u003cp\u003eGo straight to the source.

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.

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. The Intelligent Ground circuit detects whether your existing AC outlet is already grounded and only adds the supplemental earth if needed, so you can’t accidentally create a ground loop by plugging in an unnecessary ground wire.\u003c\/p\u003e\n\n\u003c!-- WHY BUY FROM AUDIO ADVISOR --\u003e\n\u003ch2\u003eWhy Buy the iFi PowerStation from Audio Advisor?\u003c\/h2\u003e\n\u003cdiv class=\"ec-titlebox-text\"\u003e\n  \u003cp\u003e\u003cstrong\u003e40+ Years of Expertise\u003c\/strong\u003e — Audio Advisor has helped over one million audiophiles build better-sounding systems since 1981.\u003c\/p\u003e\n  \u003cp\u003e\u003cstrong\u003e60-Day Money-Back Guarantee\u003c\/strong\u003e — Listen in your own room, on your own system, for 60 days.

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.

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.

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.

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.

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.

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.

That means it cleans and protects the AC power coming from your wall before it reaches your audio and video gear.\u003c\/p\u003e\n\u003cp\u003eA regular surge strip just blocks big spikes. The Elite-15 DMi does much more. It filters out the electrical noise that rides along with your power, protects your gear from surges, and even shows you how your power is doing on two front-panel meters. The “DM” in the name stands for Dual Meters. It has 13 filtered outlets and a 15-amp rating, which makes it a great fit for small to medium home theater and hi-fi systems.\u003c\/p\u003e\n\u003cp\u003eFurman has built power gear for recording studios, film, and broadcast for over 40 years.

Noisy power can add hum or hiss to your music and a soft, washed-out look to your screen.

The Elite-15 DMi lowers electrical noise, keeps digital noise away from your analog components, and shields everything from surges. The payoff is a quieter background and better-protected equipment.\u003c\/p\u003e\n\u003ch3\u003eWhat do the “dual meters” show me?\u003c\/h3\u003e\n\u003cp\u003eThe two front-panel meters show your incoming line voltage and the amount of current your system is pulling. They are dimmable, so you can turn them down for movie night. It is a handy way to keep an eye on your power.\u003c\/p\u003e\n\u003ch3\u003eDo I need anything else to use it?\u003c\/h3\u003e\n\u003cp\u003eNo extra box is needed. You plug it into a 15-amp wall outlet and plug your gear into it. It even includes a removable module to protect your coaxial and telephone lines.\u003c\/p\u003e\n\u003ch3\u003eWhat is the difference between the switched and unswitched outlets?\u003c\/h3\u003e\n\u003cp\u003eSome outlets can be turned on and off with a 12-volt trigger, so they power up with the rest of your system. Others stay on all the time, which is handy for gear you want running even when the system is “off.” Give us a call if you would like help planning which gear goes where.\u003c\/p\u003e\n\u003ch3\u003eHow is the Elite-15 DMi different from the Furman Reference models, like the IT-Reference 15i?\u003c\/h3\u003e\n\u003cp\u003eThe Elite-15 DMi brings many Furman technologies (LiFT filtering, SMP, and EVS) to a friendly price, and it is ideal for small to medium systems. The Reference models, like the IT-Reference 15i, step up with an isolation transformer, Discrete Symmetrical Power for video, and a larger current reserve for big amps. If you are not sure which fits your system, give us a call.\u003c\/p\u003e\n\u003ch3\u003eWill it change the way my system sounds?\u003c\/h3\u003e\n\u003cp\u003eA power conditioner does not add its own sound. What it does is lower noise and protect your gear, which lets your components do their best work.

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 Elite-20 PFi unique\u003c\/h3\u003e\n\u003cp\u003eThe Elite-20 PFi is the \u003cstrong\u003etop of the Elite line\u003c\/strong\u003e, and three specifications explain the step up from the Elite-15 PFi:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull 20-amp service.\u003c\/strong\u003e The Elite-20 PFi is designed to be fed from a dedicated 20-amp wall circuit (NEMA 5-20R outlet and matching power cord). Reference systems with multiple high-current amplifiers, big powered subwoofers, and a stack of front-end components can easily exceed 15A on peaks; the Elite-20 PFi accommodates that without tripping breakers or running close to its current ceiling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBigger Power Factor Technology reserve.\u003c\/strong\u003e The four amplifier outlets are fed by a PFT reservoir with roughly 4.5 amps RMS reserve and over 55 amps of peak charge — up from ~3 amps and 45 amps on the 15A version. More headroom when your amp calls for a huge transient.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWider-bandwidth ultra-linear filtering.\u003c\/strong\u003e The Elite-20 PFi's LiFT implementation starts its differential-mode attenuation curve at about 5 kHz, versus 10 kHz on the Elite-15 series — meaning it is cleaning more of the audio-band-adjacent RF and EMI that can muddy a high-resolution system. Every outlet benefits, not just the amp bank.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eYou also get two retractable front-panel LED work lights, a front-panel outlet, and the same SMP \/ EVS \/ zero-ground-contamination protection as every other model in the line. There are no meters — if you want metering plus PFT plus 20A service, you have to step up into the Reference series.\u003c\/p\u003e\n\u003cp\u003eBottom line: the Elite-20 PFi is for a reference two-channel or home-theater system whose owner wants Furman's top filtration and current-reservoir capability without crossing into isolation-transformer territory. If your dedicated circuit is already a 20A run, this is the Elite model to buy.\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 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. 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.

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.

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\u003c!-- ============ UNIQUE FEATURES ============ --\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.

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'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.

When connecting sensitive equipment to your home's power outlet, AC noise couples into your system's critical components. This AC noise masks low level signals and cripples performance.

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.

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.
