Angeboten wird „Quad 606 Endstufe High End HiFi“ von Quad als Gebrauchtgerät aus der Kategorie „Verstärker (incl. Surround)“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 4331017237 endet am 22.07.2026 um 20:48 Uhr.
This is a strong deal: at €190, it sits well below the €320 25th percentile and far under the €450 median, so it’s priced like an easy buy rather than a negotiation starting point. Against the recent EUR comp set, that’s a clear bargain.
The 606 is a respected, muscular power amp with a good reputation for grip, drive, and reliability when healthy, so the attraction here is straightforward: serious Quad sound at a very accessible entry price. At this level, a clean, working example is exactly the sort of used-listing opportunity worth moving on quickly; the main buyer check is simply that it’s fully functional and hasn’t had any neglected-amp issues lurking inside.
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.
