At S$2,800, this like-new Musical Fidelity M6s PRX sits above the 75th percentile of S$2,638 and the median of S$2,580 from your four recent SGD comparables, making it an ambitious price rather than a bargain or fair deal. It exceeds the upper quartile by roughly S$162, so while the condition is pristine, the asking price leans toward the high end of the current used market for this model in Singapore.
The M6s PRX is well-regarded for its clean 230W per channel output into 8Ω and ultra-low THD of under 0.007%, delivering tight, controlled power that suits a wide range of speakers. If this listing includes the original power cord, remote (if applicable), and box, and the seller is the original owner with no history of repair, the premium is understandable—but buyers should still expect to negotiate down toward the S$2,600–S$2,650 range to align with typical used values.

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.
