Quad II 80 Power Amplifier Pair of QUAD II 80 Monoblock Amplifiers (80W) plus power cables. Lots of reviews done on these amps. Very good condition. Sound is just perfect with my QUAD 2905's. ONO. Like a lot of reviewers say - well designed, excellent sound. Condition: Very Good Payment Method: EFT Region/State: (WA) Western Australia/Australia By CBenn 0 Comments AUD $4,700 Date: January 20, 20251 yr
Is A$4,700 a fair entry price for a modern classic valve amplifier, or is it simply too ambitious? This listing sits well above the 75th percentile of A$2,839 and nearly triples the median of A$1,415 from your own database of 21 recent AUD comparables, making it an ambitious ask rather than a bargain. While the original RRP was A$14,500, the current market clearly values these less at used prices, and this specific asking price exceeds typical transaction levels significantly.
The Quad II-eighty is a worthy buy for its 80-watt valve output and modern reliability that honors the original II’s sound, delivering clean power into 4Ω and 8Ω loads. If this unit is in excellent condition as claimed, it offers genuine sonic upside for a buyer seeking high-output tube amplification without the fragility of vintage gear. However, given the price is well above the median, you must verify it is truly pristine, includes original accessories, and has no hidden service costs 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.
