Musical Fidelity X-150 Integrated Amplifier with power cable and remote included. It is in excellent condition (no visible scratches or wear), and is fully functional. 141W per channel at 4 ohms, 105W at 8 ohms. Original owner (who I am listing this on behalf of) said that this amp sounds wonderful, and research online suggests most people agree it is phenomenal for desktop speakers. Original retail price was $995!
This is a fair ask. At US$499, it sits just above the US$493 median for recent comps and well within the US$459–US$582 middle band, so it’s neither a bargain nor ambitious.
This model has a solid reputation for a lively, full-bodied presentation with enough drive to make speakers feel properly controlled, which is why it stays desirable on the used market. If the unit is clean, fully functional, and comes with the original remote and packaging, it’s a sensible buy; I’d mainly want confirmation of quiet operation, no switching issues, and stable channel balance given the age of these integrateds.
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.
