Our Thoughts RADAR AI

This is a fair-to-good buy, and the timing matters less than the fact that the M6si is a mature, established design rather than a fast-changing current model. At £981, it sits below the £997 25th percentile of your recent GBP comps, so this is a solid deal rather than merely fair.

What makes it attractive is the core proposition: a 220Wpc integrated with a strong phono stage, DAC input, and the sort of grip and drive the M6si is known for. It’s a well-liked all-rounder for speakers that appreciate current and control, and at this price the value is good if the unit is clean and fully working. With condition listed as unknown, I’d want confirmation on function, remote, and any service history, but the number itself is already in buyer-friendly territory.

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.
