Overview
The Musical Fidelity X-Power Power Supply is a purpose built linear power supply designed to give your source components and low power electronics the kind of clean, stable, quiet feed that lets them perform at their best. If you have ever wondered why a modest component sometimes sounds bigger and more composed once its power is sorted out, this is the piece that addresses that directly. It is a foundation product, the sort of upgrade that does not change what your gear is but rather lets it deliver more of what it already has.
Musical Fidelity has a long history of treating the power supply as a serious part of the audio chain rather than an afterthought, and the X-Power carries that thinking into a compact and approachable enclosure that fits neatly alongside the rest of a system.
Design and Build
This is a true linear power supply, not a switching design, and that distinction sits at the heart of its appeal. Inside you will find copper foil shielding, generous 10,000 uF filtration using low ESR capacitors, and precise voltage rectification. The result is a supply engineered to deliver steady voltage with very low noise, so the components downstream are not fighting hum, ripple, or the electrical grime that rides in on a typical wall outlet.
Protection has clearly been a priority. The X-Power includes a soft start system to avoid the abrupt inrush that stresses components at power up, along with surge and overvoltage protection to guard your gear. There is also an EMI and RFI filter plus a DC blocker built in, with RFI attenuation quoted up to 80 dB. That combination tackles both the high frequency hash that muddies audio and the DC offset on the mains that can make transformers buzz mechanically.
Practical Details
With a maximum output of 10A and a modest footprint of 274 by 108 by 105 mm, the X-Power slots easily onto a rack shelf or beside a component. At 1.73 kg it is light enough to place without fuss yet solid in feel. It is a tidy, unobtrusive box that does its work quietly and stays out of the way.
Sound Character
A power supply does not have a sound of its own in the way a loudspeaker or a cartridge does, but its influence is unmistakable once it is in place. Feeding a component from the X-Power tends to lower the perceived noise floor, and that alone opens up a sense of space and calm between notes. Low level detail becomes easier to follow, transients feel more assured, and there is often a steadier, more grounded quality to the bass because the supply is not sagging when the music demands current.
What listeners usually describe is not a change in tonal balance but an increase in composure. Voices sit more clearly, the presentation feels less strained, and busy passages hold together rather than turning congested. That is the signature of clean regulated power doing its job.
Where It Fits in the Musical Fidelity Range
The X-Power name spans more than one dedicated supply. This standard X-Power Power Supply is the versatile member of the family, aimed at feeding suitable Musical Fidelity electronics and compatible low power components that benefit from an external linear feed.
If your priority is analog playback, the closely related Musical Fidelity X-Power TT Turntable Power Supply is tailored to turntable duty, offering the same family approach to clean power in a version focused on the specific needs of a deck and its motor. Choosing between them comes down to what you want to power. For general component support the standard X-Power is the natural pick, while the TT variant is the one to reach for when a turntable is the star of your setup.
Who It Is For
The X-Power is for the listener who has assembled a system they enjoy and now wants to extract the last measure of refinement from it. It suits anyone running a compatible Musical Fidelity component or a low current source that ships with a basic supply and deserves better. It is also a smart choice for a listener in an electrically noisy home, where nearby appliances, dimmers, and chargers pollute the mains and rob a system of its quiet backdrop.
If you value a calm, low noise presentation and you are the type who enjoys thoughtful, foundational upgrades, this is exactly the kind of component that rewards attention.
Ideal System and Use
Pair the X-Power with a suitable component that accepts an external linear supply and place it on a stable shelf with a little breathing room. Because it addresses both DC offset and high frequency interference, it is especially valuable in a compact desktop or shelf system where everything sits close together and cross contamination of noise is common. In a full sized rig it earns its place by giving a source or preamp a cleaner electrical environment than the wall alone can offer.
How It Compares to Other Options AEA Carries
It helps to understand the difference between a dedicated component supply like the X-Power and the broader family of mains conditioning products, since they solve related but distinct problems and many listeners eventually use both.
The Silent Angel Forester F1 Dual Output Linear Power Supply is another linear supply worth considering if you want to feed more than one device, thanks to its dual output arrangement. It appeals to the listener juggling several low power components who prefers to consolidate their clean power into a single unit.
For whole system mains treatment, the Audioquest PowerQuest 3, PowerQuest 303, and the more capable PowerQuest 505 take a distribution and conditioning approach, filtering and protecting everything plugged into them. If your goal is to clean up the power reaching an entire system rather than a single component, these are the direction to look, with the higher numbered models offering more within that same line.
The Audiolab DC Block 6 focuses specifically on removing DC offset from the mains across multiple outlets, which is a great complement when transformer hum is your main complaint. Think of these conditioners and blockers as system wide hygiene, while the X-Power is a targeted, dedicated feed for a single component. Many enthusiasts happily run one of each because they address the problem at different points.
