Musical Fidelity M6S PRX Power Amplifier

Praised by Hi-Fi+ as "a true world-class product", the M6s PRX is a 230 Watts-per-channel power amplifier with a unique Choke Regulated Power Supply (CRPS).

The M6s PRX shares the same basic circuit topology as it's premium Titan or AMS50 siblings, but the CRPS gives it a technical twist of its own, enabling performance levels that eclipse its rivals.

Its awesome combination of precision and power means the M6s PRX can drive even demanding speakers with complete neutrality.

Hi-Fi Choice said the M6s PRX has an "aura of unflappable invincibility. You can push the amp hard without ever sensing that it's struggling".

These sentiments were echoed by the Hi-Fi+ review, which described the M6s PRX as having "an effortless quality it almost makes your speakers seem bigger and better than they really are."

The M6s PRX is also a flexible design, featuring two sets of switchable inputs. Its line output sockets also allow it to be easily used in a bi-amp or even tri-amp configuration.

Design & Build

The M6s PRX shares the same high-quality fit and finish that runs across the M6s range. Its top-grade metal casing makes a style statement while providing performance-boosting solidity.

Inside the custom-made chassis sits the same dual-mono design boasted by our very best power amplifiers. But what sets the M6s PRX apart is its unique Choke Regulated Power Supply (CRPS).

A choke, which offers high resistance to AC and very low resistance to DC, offers a hugely effective solution to power-supply noise. Chokes were commonly used on traditional tube amplifiers, but we were the first to use them with transistor designs. We also exclusively use a dual bifilar choke system for the ultimate in noise rejection.

The CRPS also provides outstanding mains noise filtration and rejection, ensuring low-noise power supply performance and immunity from main-borne interference. You won't even have to think about adding a mains conditioner to the M6s PRX.

The sonic effects of our CRPS are amazingly quiet background, precise imaging, and fine detail recovery. Add the power, pace, and dynamics delivered by the core 230-watts per channel design and it's easy to see why the M6s PRX is described as a truly world-class amplifier, capable of effortlessly driving speakers.

Twin, switchable inputs, and flexible output options allow the M6s PRX to be used in a wide range of systems. Its ideal pre-amplifier partner is the matching

M6s PRE. To quote the HiFi+ review of the two in tandem: "It's the perfect combination of motive force and grace".
