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 6920217286 ends on 01.12.2026 at 18:46 o'clock.
This is a buyer’s market: at €2,995, the asking price is a genuine bargain for a used SR-009S. It sits €70 below the recent 25th-percentile asking price of €3,065, and well below the €3,640 median; it is also comfortably under the €4,050 75th-percentile mark. On these numbers, the price is notably attractive rather than merely fair.
The SR-009S remains one of Stax’s finest earspeakers, combining exceptional resolution, speed, openness, and low-level detail with the effortless presentation electrostatics do particularly well. At this money, it is a compelling entry into the top tier, assuming the listing is complete and the unit is electrically healthy. Confirm that the dedicated Stax bias connector and cable are included, inspect the pads and headband, and—ideally—ask for a brief listening or amplifier test before committing.

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.
