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 3530789946 ends on 03.01.2027 at 15:37 o'clock.
At €3,595, this is a fair-to-good buy, sitting just €8 below the €3,603 median and comfortably below the €3,752 75th percentile, though not a bargain at the €3,078 25th-percentile level. Assuming the condition is as described, the price is properly positioned for a desirable flagship electrostatic rather than inflated.
The SR-009S remains compelling for its exceptionally clean, fast, transparent presentation, spacious open-back design, and comfortable leather pads. Its refined MLER2 drivers and solid aluminum construction make it a serious long-term listening piece, especially for classical, acoustic, and vocal music. Confirm that the original case and fixed 2.5 m cable are included, and remember that it requires a Stax-compatible 5-pin PRO energizer; without one, the apparent saving can disappear quickly.

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.
