Timing matters here because this is still Stax’s current flagship, so you’re not buying into an obsolete generation. Against your recent EUR comps, €6,600 is above the 75th percentile of €5,949, so this reads as ambitious rather than fair for a used unit; the premium needs to be justified by exceptional condition, full packaging, or extras.
That said, the SR-X9000 is a seriously respected electrostatic: ultra-clean, fast, spacious, and resolving in the way Stax fans chase. If this one is genuinely good condition and complete, the upside is buying the top of the line without new-retail pain, but I’d still want to see strong included accessories and proof it’s been well cared for before paying this much.
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.
