At £105, this looks like a strong bargain if it’s the 7-channel Musical Fidelity M6x 250.7, which launched around £3,099 and sits in the serious multichannel power-amp class. Even allowing for a big gap between new and used, £105 is well below where a working example would normally land, so the only real question is whether the listing is accurately identified and fully operational.
That model is well regarded for its heavy-duty build, clean all-channels-driven power, and the sort of effortless grip that suits home cinema or a high-end active setup. If the amp is complete, quiet, and unmodified, it’s an easy “buy fast” price; just verify it powers up properly, all channels work, and there’s no sign of overheating or relay issues.
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.
