This is more than a used vintage device.

Many similar units online may be cheaper, but they may also be dusty, incomplete, unserviced, cosmetically weaker, or sold without proper testing.

Compared with the obvious alternative of a newer integrated amplifier at this money, USD 1,391 is ambitious for a used Musical Fidelity A100. Your three comparable listings put the median at USD 931, with the 75th percentile at USD 1,161, so this sits clearly above the normal market unless it has exceptional provenance or recent professional restoration.
The A100 remains a very appealing vintage amplifier: its warm, fluid presentation, clear midrange, built-in phono stage, and roughly 50-watt high-Class-A design can make an excellent partner for reasonably sensitive speakers. It also has genuine character rather than merely nostalgia. However, these units run hot, and fan condition, ventilation, dried capacitors, and evidence of a proper recap or service matter materially with age. At this asking price, look for documented refurbishment, quiet fans, and unusually clean original condition; otherwise, negotiating toward the USD 931–1,161 range would be sensible.
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.
