This is a seller’s market for the M6s Pre at this ask: at US$1,459, it sits exactly at the 75th percentile of the recent comp set and well above the US$1,321 median, so it’s not a bargain. It’s a top-of-range price rather than an obvious overreach, but buyers should expect to pay for a clean example rather than value-hunt here.
That said, the preamp itself is a strong piece: Musical Fidelity’s M6 series is well regarded for a quiet, open, and authoritative presentation, with enough drive and control to anchor a serious system without sounding etched. If the unit is complete, tidy, and from a careful owner, the appeal is the sound-to-build ratio and the fact that good preamps tend to age more gracefully than many digital pieces; just make sure the remote, packaging, and any phono or balanced-related accessories are present, since those matter more when you’re already paying near the upper end.
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.
