At £435, this sits a touch above the £367 median and just over the £433 upper quartile for recent UK asks, so it reads as a slightly ambitious but still defensible price rather than a bargain. It’s not overpriced enough to dismiss, but it leaves less room for negotiation than a mid-market listing.
The M2si is a well-liked, no-nonsense integrated with the kind of clean, composed drive that suits a wide range of systems, so a tidy example can be an easy live-with purchase. If it’s complete, unmodified, and clearly well cared for, the value is in buying a solid, proven amp with broad appeal; at this level, just confirm normal basics like remote, all inputs working, and sensible cosmetic condition.
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.
