Versus a new integrated at this money, this used M2si looks sensibly priced rather than a steal, sitting a touch above the £363 median and below the £421 75th percentile for recent UK comps. At £409, it’s fair market value: not the bargain-bin buy, but still reasonable if the condition is clean and it’s from a careful owner.
The M2si is well liked for straightforward, punchy sound and real drive, which makes it an easy recommendation for someone wanting a no-nonsense amp with enough current to make speakers wake up. If the listing includes the remote and original packaging, that adds a little confidence and resale ease; otherwise, this is still the sort of used piece worth considering when you want solid Musical Fidelity performance without paying top of the range.

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.
