At £1,027, this sits below the £1,106 median and just above the £997 25th percentile, so it reads as a solid buy rather than a bargain-basement steal. It’s priced a touch under the middle of the recent market, which is exactly where a sensible used listing should land if it’s clean and functioning.
That makes it attractive because the M6Si is a respected, no-nonsense integrated: powerful, full-bodied, and very capable with real speakers rather than being a polite lightweight. If the unit is original, tidy, and includes the remote and box, that strengthens the value further; at this price, I’d mainly want confidence that it’s been well cared for and isn’t hiding any age-related issues.

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.
