Seller's Description

Verkaufe meine Quad 306 Endstufe. Der Zustand ist absolut top, wird so kein zweites Mal angeboten!

Elkos 2025 neu und Eingangsempfindlichkeit gemäß Dada Upgrade geändert, jetzt 1V anstelle der originalen 0,375 V, damit kann die 306 problemlos mit „neueren“ Vorstufen gepaart werden.

Alle weiteren Beschreibungen erspare ich mir, wer hier „gelandet“ ist weiß Bescheid.
Alle weiteren Infos/Fragen gerne per PN.

Am liebsten per Abholung inkl. Probehören

Our Thoughts RADAR AI

This is an ambitious ask, not a deal. At €520, it sits well above the comparable market: the median is €368, with the upper quartile at €418. Even in excellent condition, that is roughly €100 beyond where three-quarters of recent asking prices fall, so it only makes sense with unusually strong service history or desirable original-owner provenance.

The Quad 306 remains a likeable, compact 50-watt-per-channel power amp, valued for its open, organic presentation, deep bass, and sensible speaker compatibility. It is a particularly neat partner for a Quad-based system and offers more musical charm than its modest size suggests. Before paying this premium, verify channel balance, quiet operation, and evidence of servicing: these are now elderly units, and aged capacitors or PCB damage around the transformer can matter more than a clean case. At this price, documented refurbishment should be expected.

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.
