Offered is „SR-009S Silver Kopfhörer - optional im SET mit STAX SRM 700S Kopfhörerverstärker“ 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 1614256632 ends on 05.12.2026 at 16:43 o'clock.
The timing matters mainly because the SR-009S remains Stax’s current reference electrostatic headphone rather than an obsolete generation, so this is still a relevant buy. At €3,595, the asking price is essentially on the used-market median of €3,644, comfortably inside the observed €3,071–€4,053 range: fair, but not a bargain.
Its appeal is the combination of exceptional resolution, spacious imaging, speed, and a more refined, controlled balance than earlier flagship Stax models. For someone already invested in a suitable Stax energizer, this is a serious endgame headphone and a sensible way to acquire one below typical new pricing. The value improves materially if the listing includes the original case, cable, packaging, and clear ownership history; otherwise, the price is best viewed as fair rather than irresistible.

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.
