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 9314527870 ends on 27.10.2026 at 18:55 o'clock.
This is an ambitious ask, not a deal: at €5,795 it sits well above the €5,507 75th percentile and far above the €3,558 median for recent used EUR listings. It would need to be exceptionally clean, complete, and ideally from a careful owner to justify that premium.
That said, the model earns its reputation: the SR-009S is prized for speed, resolution, and a very refined top end, with electrostatic transparency that still puts it among the reference headphones for detail lovers. At this price, the key upside is only if the set includes the original box, cables, adapters, and shows strong condition history; otherwise, this is a “buy only if you specifically want this exact headphone” listing.

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.
