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 5413863479 ends on 16.11.2026 at 17:58 o'clock.
For SR-009S buyers, this looks like a seller’s market but the ask is still fair: at €3,595 it sits essentially on the €3,589 median, just above the typical middle of the used market and well inside the normal band from about €3,011 to €4,237. That makes it a sensible buy rather than a bargain-basement score, but also not an inflated ask.
What makes it worthwhile is the SR-009S itself: top-tier electrostatic speed, openness, and microdetail, with a presentation that still ranks among the most resolving in headphones. If this is clean and complete, the value case is strong for someone who already owns the right energizer and wants a reference-level Stax without waiting for a deeper cut. At this price, the key is condition and accessories; a tidy, well-kept set is the main upside.
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.
