Our Thoughts RADAR AI

This is a fair ask: GBP156 is exactly the median of five recent comparable listings, comfortably within the normal market range of GBP106–GBP621. It is not a bargain on price alone, but neither is it ambitious; for a working, sensibly presented example, the figure is defensible.

The Quad 22 remains a highly characterful valve control unit, particularly attractive in a period Quad II system. Its flexible phono equalisation, tone controls and distinctive filtering give it real usefulness rather than merely vintage appeal, while its compact, beautifully engineered layout is a major part of the charm. At this price, prioritise confirmation that both channels, controls and phono stage operate quietly, and ask whether the capacitors and resistors have been checked or replaced: age-related servicing can materially affect performance. The original connectors and accessories also matter.

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.
