Seller's Description

Only 6 months old and absolutely as new. Faithful reproduction by IAG of Peter Walker s seminal design and exquisitely executed. The power amp is a particuler joy to behold. As RR would say power is sufficient for most application, presently driving some smaller ATC s without fuss in a modest sized room. Sound is sweet reminiscent of my valve stuff. All boxes held, demo welcome, no couriers allowed near the duo, I m Cheshire based. rn

Our Thoughts RADAR AI

At £1,250 for an excellent-condition used Quad 33/303 pair, this is a strong bargain compared to the typical used market, sitting well below the 25th percentile of £683–£1,951 and notably under the median of £1,547. It also represents exceptional value against the current new price of roughly £2,400 for the pair (£1,200 each).

This revived classic is well-regarded for its substantial aluminium chassis, 50W per channel Class AB power, and the ability to bridge into a potent 140W mono-block, delivering the clean, controlled sound Quad fans cherish. At this price, you’re getting a modern build with vintage DNA, complete warranty on new units (if bought new), and a rare opportunity to own a half-rack, high-current amp that’s both timeless and contemporary—no caveats needed for a clean listing at this level.

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.
