Our Thoughts RADAR AI

The Musical Fidelity M6si’s £1,200 asking price is exactly in line with the recent comparable market: the median is £1,200, with typical examples spanning roughly £1,034 to £1,498. That makes this a fair, market-correct price rather than a bargain, but certainly not ambitious.

It remains a very capable buy if the condition is sound. The M6si delivers a substantial 220 watts per channel, drives difficult speakers confidently, and combines a clean, powerful presentation with useful MM/MC phono, balanced XLR, line inputs and USB connectivity. At this price, confirm the remote, original packaging and all inputs work properly, and check for signs of overheating or noisy controls; otherwise, a healthy example offers serious performance and plenty of headroom for the money.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About Musical Fidelity

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.
