£586 looks like a fair-to-good ask for a Quad Elite QSP in today’s used market, especially if it’s clean and working properly. New examples were around £1,200, and recent used pricing I’ve seen sits roughly in the £500–£650 band, so this is near the sensible middle rather than a bargain-bin win.
It’s worth buying because the QSP is a genuinely respected power amp: smooth, controlled, and capable of real current delivery, with enough drive for demanding speakers and Quad’s own ESLs. If the listing includes box, manual, and proof of recent servicing, that adds real value here. At this price, I’d mainly just confirm channel balance, relay/start-up behavior, and that the seller can describe any service history clearly.

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.
