Condition is unknown, which keeps the price from feeling like an automatic bargain, but at £875 this sits well above the recent used median of £371 and even above the £590 75th percentile, so it reads as ambitious rather than fair. For a buyer, that means you should only pay up if this example has genuinely strong presentation, fresh servicing, or extras that matter.
The upside is that this is a serious, well-liked stereo power amp with plenty of current-delivery muscle and a clean, modern Quad aesthetic, so it can be a very satisfying step up if you want authority and control without fuss. If it has been looked after, still carries its original packaging or accessories, and the seller can show a clean history, it’s a capable long-term buy — but at this asking level I’d want those details nailed down before committing.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Quad, the venerable British hi-fi brand, traces its origins to 1936 in London, when engineer Peter J. Walker founded S.P. Fidelity Sound Systems, soon renamed the Acoustical Manufacturing Company. Relocating to Huntingdon in 1941 after wartime bombing, the firm shifted from public address gear to domestic audio amid post-war demand for superior sound reproduction. Walker's pioneering ethos—prioritizing "the closest approach to the original sound"—defined Quad from its early QA12 amplifiers, adopted by the BBC, to the iconic Quad I of 1953.
The brand excels in amplifiers and electrostatic loudspeakers, revolutionizing both categories. The Quad II power amplifier of 1953 introduced cathode coupling for vanishingly low distortion, while the 1956 ESL 57 delivered the world's first full-range electrostatic speaker, employing a massless film diaphragm for unparalleled transparency and transient speed. Quad advanced into solid-state with the 1967 303 and transistor designs featuring innovative "Triples" output stages, later expanding to integrated amps like the 99 series, moving-coil speakers, and modern electrostatic models such as the ESL 988 and 989.
Today, under the International Audio Group since 1997, Quad holds a prestigious position in the high-end market, revered by audiophiles for its unyielding pursuit of accuracy over trends. Its heritage components command vintage collector status, yet contemporary offerings maintain a niche boutique appeal among discerning buyers seeking refined, distortion-free reproduction that honors Walker's legacy.
