This Quad 44/405-2 combination is in near mint condition, with its original boxes and bill of sale, and in full working order (recently service). It’s a classic combination that offers great versatility. I’m only the second owner of these so I know that they’ve been very will taken care of. I am selling ‘as described’ simply because they are vintage items.Sadly, house renovations demand I pare down my collection of hifi gear, simply for the space! So this must go. I will also be listing some ESL-63 speakers that pair brilliantly with these. This is located in Cheshire, from where collection is welcome. Otherwise, I’m happy to post. Any questions, feel free to ask. Thanks for looking.
With unknown condition on this used Quad Classic integrated amp listed at USD953, that's smack in the median of recent comps—USD650 at the 25th percentile up to USD1,080 at the 75th. It's a fair ask if it's in solid cosmetic shape without battle scars, aligning neatly with the typical used market range for these British classics; no bargain steal, but not ambitious either unless it's pristine.
Buyers, prioritize a full service history check—Quad amps from this era often need recap of electrolytic caps after 20-30 years to avoid hum or channel imbalance. Verify inputs/outputs function cleanly, and confirm the original power cord and manual are included; missing bits can add USD100-200 to restore costs. Test with your speakers 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.
