Aus der privaten HiFi-Sammlung biete ich hier ein hochwertiges Stax DA-100M Class-A Monoblock Endstufen-Paar an.
Beide Geräte funktionieren grundsätzlich, wurden jedoch längere Zeit nicht mehr genutzt (aber vor Kurzem auf Funktionalität geprüft).
An einem der Geräte ist an der Front ein kleiner Kratzer (siehe Foto).
An diesem Gerät ist der Ein/Aus-Schalter beim wiederholten Testen nicht mehr eingerastet. Vermutlich ist das eine Alterserscheinung, die leicht zu beheben ist. Das Gerät funktioniert aber grundsätzlich.
Der Verkauf erfolgt privat unter Ausschluss jeglicher Sachmängelhaftung.
Aufgrund der Wertigkeit der Geräte und des Gewichtes ist nur eine Abholung und kein Versand möglich.
At €1,300, this sits well above the current €808 median and also above the €1,054 75th percentile, so it reads as ambitious rather than fair on the recent comparable EUR market. The gap is large enough that I’d only bite if this one brings something clearly special—top cosmetics, confirmed servicing, scarce accessories, or unusually strong provenance.
That said, this is a respected Stax monoblock and the appeal is real: it’s the sort of amp people buy for speed, control, and a very clean, authoritative presentation. If it’s genuinely good condition and complete, the upside is in getting a desirable, specialist piece that doesn’t show up every day; just make sure the seller can document working status, channel matching, and any original extras before paying this kind of premium.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Stax traces its origins to 1938 in Tokyo, Japan, when Naotake Hayashi founded Showa Kouon Co., Ltd. in Chiyoda-ku. Initially focused on wax disc recording, metal master production, and audio equipment for film soundtracks, the company evolved through the postwar era. In 1950, it launched its first high-frequency condenser microphone, adopted by NHK, and renamed itself STAX Co., Ltd. in 1963, honoring its pioneering Stax-1 mic. A brief suspension in 1995 due to economic pressures gave way to revival, preserving its legacy under family leadership.
The brand specializes in electrostatic headphones, known as "EARSPEAKERS," debuting with the world-first SR-1 in 1960. This innovation spawned enduring lines like the SR series, produced for decades with incremental refinements for superior resolution and staging. Stax complements these with dedicated electrostatic amplifiers and select accessories, eschewing conventional speakers, turntables, DACs, or cables to hone its transducer expertise.
Stax commands a niche high-end position among audiophiles and professionals, revered for unmatched transparency and fidelity that rivals cost-no-object loudspeakers. Its 85-year heritage cements it as a boutique icon in electrostatic technology, far from mass-market fare, appealing to discerning buyers seeking pinnacle sonic transduction.
