Compared with the obvious alternative at this price—a newer, less powerful integrated—the M6Si at £1,250 looks like a strong buy. It sits below the £1,313 median from 16 comparable listings and comfortably above the £1,037 25th-percentile threshold, so it is not quite a bargain, but it is plainly better than merely fair value.
The appeal is substantial current delivery: 220 watts per channel, a quiet and composed presentation, useful balanced input, switchable MM/MC phono, and USB input. It is an especially capable partner for difficult speakers or a larger room, combining grip and scale without sounding crude. With condition listed as unknown, confirm the remote, check both channels and the phono/USB inputs, and look for clean cosmetics and sensible ventilation. If those basics check out, £1,250 is an attractive asking price.

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.
