Offered is „SRM 700S Kopfhörerverstärker - optional im SET mit STAX SR-009S Silver Kopfhörer“ by STAX as new device from the category „Headphone Amplifier“ on audio-markt.de - the online market place for high-end. The advert with the number 1924772061 ends on 27.12.2026 at 16:15 o'clock.
At €2,995 in clean condition, this is a strong deal: it sits below the €3,092 25th-percentile mark and well under the €3,669 median from 45 comparable used listings. For a properly presented SR-009S, that is bargain territory rather than merely fair pricing.
The SR-009S remains a flagship-level electrostatic ear-speaker, prized for exceptional resolution, speed, transparency, and controlled, articulate bass. Its MLER2 electrodes and refined construction give it a more focused, incisive presentation than the original SR-009. Just confirm the included 5-pin Pro-bias cable, pads, and case, and remember that it requires a compatible Stax energizer; otherwise, this looks like an unusually attractive entry into top-tier Stax.

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.
