Offered is „SET: SR-009S Silver Kopfhörer & Kopfhörerverstärker SRM 700S“ by STAX as new device from the category „Headphone“ on audio-markt.de - the online market place for high-end. The advert with the number 1575432343 ends on 17.11.2026 at 18:00 o'clock.
A flagship electrostatic like this is always going to draw attention, and the asking price sits above the recent used market. With a median of €3,600 and a 75th percentile of €5,028, €5,795 is clearly ambitious rather than fair-value territory.
That said, the SR-009S is famous for speed, resolution, and effortless treble detail, so a clean example can still make sense for someone chasing top-tier Stax performance. The main upside here is simply getting into a highly regarded reference headphone, but at this level buyers should want proof of condition, pads, cable, and healthy channel balance before paying a 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.
