X-Power
The Musical Fidelity X‑Power is a high‑performance line power conditioner designed to deliver ultra‑clean, stable mains power for sensitive audiophile systems, combining surge protection, EMI/RFI filtration, and DC blocking in one compact unit.

Design Excellence

The X‑Power is engineered in the classic Musical Fidelity X-Series profile, featuring a single inlet and outlet configuration that prioritises purity and stability in power delivery. Its chassis is formed from a one‑piece aluminium extrusion, providing outstanding shielding against electromagnetic interference for reliable, noise‑free operation.

Advanced Surge & Overvoltage Protection

To safeguard valuable audio equipment, the X‑Power incorporates a sophisticated multi‑stage surge and overvoltage protection system, with one protection stage at the input and another at the output. These stages defend your system against surges caused by lightning strikes, grid fluctuations, or sudden electrical load changes by safely diverting excess voltage away from connected components.

High‑Performance EMI/RFI Filtering

Unwanted electromagnetic and high‑frequency interference can degrade audio clarity, adding noise and distortion. The X‑Power combats this with a bespoke EMI filter using precision‑matched chokes and capacitors, supported by a further protection stage. Its measured attenuation levels reach nearly –60 dB at 100 kHz and surpass –80 dB at 1 MHz, delivering exceptionally clean power for superior sonic performance.

Precision‑Engineered DC Blocker

DC offset on the mains can reduce transformer efficiency, introduce mechanical hum, and compromise audio quality. The X‑Power eliminates these issues through a carefully designed network of diodes and electrolytic capacitors that blocks DC components while allowing AC to pass freely. Since most amplifiers and preamps do not include DC blockers as standard, the X‑Power provides vital protection and performance enhancement for any revealing audio system.

Optimised for Sources & Amplifiers

With a 10A power rating, the X‑Power can supply clean power to multiple audio sources such as CD players, DACs, preamps, phono stages, and streamers. When used with a high‑quality unfiltered power strip, it supports around six or more typical source components, thanks to a maximum throughput of 2300W at 230V. It is advisable to keep analogue and digital source components on separate power strips, and each amplifier should be connected to its own dedicated X‑Power unit to ensure optimal performance and isolation.

In Stock products are those that are currently held in stock at our Oxfordshire warehouse. This stock status is updated regularly but is subject to change at very short notice.

Products that are Awaiting Stock are items that we would normally carry on stock at our Oxfordshire warehouse, but are currently unavailable. Chances are there is already more on the way, but if you would like a more accurate availability status please feel free to Contact Us.

Urgent order items are products that we do not normally carry on stock, but they are typically held on stock by our European suppliers. Depending on availability, we will seek to order these products quickly, when we have an enquiry. They can therefore be subject to quicker availability times than "Special Order" products.

Special Order items are those that are most often built to order. For these items, we tend to experience longer lead times as we negotiate them into the production line with our suppliers.

Exclusive products are sold only through one, or sometimes a very small number of dealers. As part of their commitment to the product’s exclusivity, they carry most of the available stock.

RRP: £419.00

The Musical Fidelity X‑Power is a high‑performance line power conditioner designed to deliver ultra‑clean, stable mains power for sensitive audiophile systems, combining surge protection, EMI/RFI filtration, and DC blocking in one compact unit.

  • Rated at 10A when used with 230V the maximum power throughput is 2300W (1100W when used in 110V regions). As a general rule of thumb, one source 
    consumes between 20 - 40W. You can comfortably connect 6 and even more sources at the same time.

    Note: we recommend to not mix digital with analogue source devices.

  • General formula for 230V (adjust accordingly for 110V): (channels x amp power @ 8 Ohm) x efficiency headroom < 2300W

    Class AB: Calculating a headroom of 50% for the lesser efficiency of Class AB and to account for proper peak power delivery, we can safely say that the X-Power handles stereo amps around 700W and even more. (2 x 700W) x 1,5 headroom < 2300W

    The power consumption of Class AB is proportional to the listening level, so in typical listening scenarios, Class AB amps draw much less power than in 
    the above calculation.

    Class A: Class A draws the same amount of power at full or minimum volume level. Calculating a headroom of 100%, the X-Power handles Class A stereo amps up to 2 x 550W. 

    Tube Amps: standard tube amps have an efficiency of 20%. The X-Power is able to handle tube amps up to 2 x 200W.
