Our Thoughts RADAR AI

At £721, this Quad QC Twenty Four with phono stage is ambitious, sitting well above the median used price of £389 and exceeding the 75th percentile of £616 from your 175 comparable GBP listings. While new units currently ask around £999–£1,095, the used market typically ranges from £249 to £616, making this £721 asking price roughly 17% higher than the top quartile. It’s not a bargain, but it’s not absurd if the condition is truly “excellent as new” and the phono stage is included—a feature that adds value.

The QC24 is well-regarded for its sweet, full-bodied valve sound, thanks to its soldered 6111WA twin-triode tube with a 60,000–100,000-hour lifespan, and it pairs especially well with Quad’s valve power amps. If this listing is from a clean, original-owner box with the phono stage intact, it could still be a worthwhile buy for someone seeking that classic Quad warmth—just be prepared to pay above typical used rates for the added convenience and proven condition.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About Quad

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.
