Offered is „SR-X9000“ by STAX as second-hand device from the category „Headphone“ on audio-markt.de - the online market place for high-end. The advert with the number 8955200569 ends on 12.11.2026 at 15:33 o'clock.
The SR-X9000 sits at the top of Stax’s lineup for a reason, and at €3,300 this one looks like a strong deal versus the recent used-market median of €3,953 and well below the €3,627 25th percentile. That puts it in bargain territory rather than merely “fair.”
What makes it appealing is the combination of reference-level electrostatic resolution, speed, and imaging, plus the included cables and accessories, which adds real value on a premium headphone like this. In good condition, this is the sort of listing that rewards a quick decision if you already have the energizer chain in place.

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.
