Offered is „SRA-12S High-End Kopfhörerverstärker“ by STAX as second-hand device from the category „Headphone Amplifier“ on audio-markt.de - the online market place for high-end. The advert with the number 1058952945 ends on 27.10.2026 at 06:11 o'clock.
€799 is ambitious versus the recent used market, sitting well above the €790 75th percentile and far over the €326 median and €313 25th percentile. That means it’s priced at the top end of the current comparable set, so I’d only pay it if this example is notably cleaner, better documented, or more complete than the others.
That said, the unit itself is a serious piece of Stax gear: a proper energizer/preamp that pairs with electrostatic headphones and is valued for its quiet, transparent drive and classic Japanese build. If the listing is genuinely good condition, that matters on an older Stax unit, because originality and careful storage can be worth paying for. Still, at this level I’d want proof of healthy operation, no channel imbalance, and confirmation of any included leads, manuals, or original boxes.
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.
