The A$1,207 asking price is a strong deal, sitting well below the 25th percentile of A$1,212 for used Quad QC24 P units in Australia. Compared to the median of A$1,217, this listing offers immediate value, making it a genuine bargain for a buyer who secures it quickly.
This valve preamp is well-regarded for its sweet, full-bodied balance and exceptional quietness, boasting hum/noise better than −80dB thanks to its soldered 6111WA twin-triode tube that lasts 60,000–100,000 hours. It delivers a likable sound that pairs beautifully with Quad’s classic valve power amps like the 405 or Classic 2s, while offering five line inputs and buffered tape loops. At this price, it’s a clear buying opportunity for enthusiasts seeking vintage tube warmth without the usual risk or cost.

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.
