The M6si is a notably powerful, generously equipped integrated rather than a merely competent all-rounder. At £1,180, this looks like a strong deal: it sits below the £1,250 median and comfortably above the £1,046 25th-percentile bargain line, making it good value rather than an absolute steal. For a clean, fully working example, the asking price is very reasonable.
Its appeal is the effortless 220W-per-channel output, high-current drive and unusually useful connectivity: MM/MC phono, balanced XLR, multiple line inputs, pre-out and USB DAC. It has the grip for difficult speakers but remains smooth and composed, with plenty of scale and low listening fatigue. Check that the remote, phono and USB inputs work properly, and confirm condition in person; otherwise, this is exactly the sort of substantial, long-term amplifier that can anchor a serious system.
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.
