This £1,295 asking price is ambitious, sitting clearly above the 75th percentile of £1,190 and well beyond the median of £1,090 for comparable used Musical Fidelity M6PRX units. While not a bargain, it reflects the premium nature of this dual-mono, 260-watt-per-channel amplifier, which delivers exceptional current and a warm, natural sound prized by enthusiasts. The unit’s rarity—limited to just 500 units globally—and its reputation as a world-class product make it a compelling buy for those seeking high-end performance, provided the condition is verified and accessories are included. At this price, buyers should expect original-owner care and no hidden defects to justify the upward stretch.
The M6PRX stands out for its choke-regulated power supply, delivering clean power with THD under 0.007% and noise below 120dB, ensuring silence with sensitive speakers. Its flexible input options and robust build (19.7kg) add to its appeal. Since the price exceeds the median, verify the condition carefully: check for wear, ensure all original cables and documentation are present, and confirm no prior repairs. If the listing is clean and complete, this remains a worthwhile opportunity for a serious collector, as the amp’s sonic character and scarcity seldom appear at fairer prices.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Musical Fidelity, a British hi-fi icon, traces its roots to 1982 when clarinettist and audio enthusiast Antony Michaelson founded the company in London. Disillusioned with the sound quality of existing gear after his stint at predecessor Michaelson & Austin, he handcrafted his debut product—a minimalist preamplifier dubbed "The Preamp"—on his kitchen table. Paired with the quirky Dr. Thomas power amplifier, these designs disrupted the market with their bold aesthetics and sonic punch, establishing Michaelson’s experimental ethos from the outset.
The brand has long centered on amplifiers as its cornerstone, spanning integrated, power, phono, headphone, and preamp models renowned for Class-AB topology and innovative touches like Nuvistor tubes. It expanded into streaming players, DACs, CD players, Bluetooth receivers, all-in-one systems, and even headphones and turntables, always prioritizing musicality over convention. Unconventional industrial designs, from curved heatsinks to sculptural panels, became signatures, influencing competitors.
Positioned firmly in the high-end arena, Musical Fidelity commands respect among discerning audiophiles for its value-driven performance and soulful sound. Iconic models like the A1 and F-series endure as collector favorites, blending accessibility with premium engineering. Acquired by Austria’s Audio Tuning in 2018, it continues evolving under new stewardship while honoring its heritage as a boutique force in British hi-fi.
