Our Thoughts RADAR AI

Are you after a compact valve preamp with character rather than the newest, most feature-packed design? At £350, this is a fair-to-slightly-strong asking price: it sits above the £283 median but comfortably below the £452 75th percentile from 27 comparable listings. It is not a bargain, but it is within normal enthusiast-market territory.

The X PRE remains appealing for its minimalist Class A single-ended-triode circuit, four line inputs, compact build, and two ECC88 valves. It is known for a sweet, spacious presentation with good midband resolution, while its simple layout makes it easy to integrate with a power amp. Check that the correct 12V AC supply is included, confirm both channels are quiet, and allow for valve age; with a working original supply and healthy valves, £350 is defensible, though a little negotiation would improve it.

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.
