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

Features & Specifications
Protection & Filtering
Two-Stage Surge & Overvoltage Protection — Protection circuits at both the input and output stages guard your equipment against voltage spikes from lightning, grid fluctuations, or sudden electrical load changes. The redundant two-stage design means your gear is protected even if one stage is overwhelmed.
High-Performance EMI/RFI Filter — A custom filter built around dual common-mode chokes with common-mode and differential-mode capacitors suppresses electromagnetic and radio-frequency interference. Musical Fidelity claims attenuation greater than 60 dB at 100 kHz and exceeding 80 dB at 1 MHz — meaning it strips away a very high percentage of the electrical noise riding on your power line.
Integrated DC Blocker (up to 2V) — Blocks unwanted DC voltage on your AC power line using a network of diodes and electrolytic capacitors. This prevents transformer saturation, which is the leading cause of mechanical hum and reduced efficiency in audio equipment with linear power supplies.
Power Capacity
10A Rated Output — At 110V (North America), this translates to approximately 1,100 watts of clean power throughput. That’s enough to run a single amplifier or multiple low-draw source components through a quality power strip. Source gear (DACs, streamers, CD players, phono stages) typically draws 20–40W each, so you can comfortably power six or more at once.
Design & Build
One-Piece Extruded Aluminum Chassis — The main body is machined from a single aluminum extrusion in Musical Fidelity’s iconic “X-profile” shape. This isn’t just for looks — the seamless aluminum construction provides excellent shielding against electromagnetic interference.
Brushed Aluminum Faceplate — A polished, brushed aluminum front panel gives the X-Power a clean, modern look that matches well with other Musical Fidelity components.

Frequently Asked Questions
What does a power conditioner actually do?
A power conditioner cleans up the electricity coming from your wall outlet before it reaches your audio gear. Your home’s power can carry electrical noise from other devices (Wi-Fi routers, LED bulbs, chargers), voltage spikes, and unwanted DC voltage. A conditioner filters out that noise and protects your equipment from power surges. The X-Power combines all three functions — surge protection, noise filtering, and DC blocking — in a single unit.
Will the X-Power make my system sound better?
The impact of power conditioning varies from system to system and depends on the quality of your home’s electrical supply. Some listeners notice immediately reduced hum and a quieter noise floor. Others may find the benefit is more about long-term equipment protection than a dramatic sonic change. The X-Power is designed first and foremost to provide cleaner, more stable power — which gives your components the best possible environment to perform as they were designed to.
Can I plug multiple components into one X-Power?
Yes. The X-Power has a single outlet, but you can connect it to a high-quality, unfiltered power strip and then plug multiple source components into that strip. Source devices like DACs, streamers, CD players, and phono preamps typically draw only 20–40 watts each, so the X-Power can comfortably handle six or more at once. Just make sure the power strip doesn’t have its own built-in filtering, which could conflict with the X-Power’s circuitry.
Should I use one X-Power for my whole system, or separate units for sources and amplification?
Musical Fidelity recommends dedicating one X-Power per amplifier and a separate X-Power for your source components. They also suggest keeping digital devices (streamers, CD players, DACs) and analog devices (turntables, phono preamps) on separate conditioned lines. For a typical two-channel setup with one integrated amp and a few sources, two X-Power units would be ideal — one for the amp and one for your sources.
Is the X-Power powerful enough for my amplifier?
In most cases, yes. At 110V (North America), the X-Power can deliver approximately 1,100 watts. Musical Fidelity provides guidelines: it can handle Class AB stereo amps up to around 700W, Class A stereo amps up to 2 × 550W, and tube amps up to 2 × 200W. Keep in mind that Class AB amplifiers draw power proportional to listening level, so in normal use, they draw much less than their peak rating. If you’re unsure about your specific amplifier, give us a call and we’ll help you figure it out.
How does the X-Power compare to the Musical Fidelity BPC3?
The BPC3 is Musical Fidelity’s larger balanced power conditioner. It uses a toroidal transformer with two isolated 300VA output zones and four outlets — designed to power multiple components with complete zone isolation between them. The X-Power is a smaller, simpler, and more affordable single-outlet conditioner with passive filtering (no transformer). If you need multiple isolated outlet zones or have a complex system, the BPC3 is the step up. If you want straightforward, high-quality power conditioning for one amplifier or a group of source components, the X-Power is a great fit.
What kind of power cable should I use with the X-Power?
The X-Power uses a standard IEC C14 inlet, which is the same type of detachable power cable used by most audio components. It comes with a power cable in the box, but if you’d like to use a higher-quality aftermarket power cable, any standard IEC cable rated for 10A will work. Check out our power cable selection if you’d like to explore options.
What outlet type does the US version have?
The US version of the X-Power features a standard NEMA outlet. Musical Fidelity also offers Schuko (European), UK, and Australian outlet variants for other markets. If you need to verify the specific outlet type for your order, please contact us.
Can the X-Power help with transformer hum?
Possibly, yes. Transformer hum in amplifiers is often caused by DC offset on the AC power line. Even a small amount of DC voltage can cause a transformer’s core to saturate, resulting in an audible buzz or vibration. The X-Power’s integrated DC blocker is specifically designed to remove DC offset up to 2V, which can reduce or eliminate this type of hum. If your transformer hum is caused by a mechanical issue inside the component itself, a DC blocker won’t solve it — but for DC-offset-related hum, the X-Power is designed to help.
