Seller's Description

Te koop: stax sr-009 + high-amp alpha centauri hybride versterker een absolute droomset voor de liefhebber van het allerhoogste niveau head-fi: de legendarische stax sr-009 elektrostaten in combinatie

Our Thoughts RADAR AI

The timing matters a bit because this is the original SR-009, not the newer SR-009S, so buyers are usually looking at it as a value play rather than the latest generation. At €2,850, it sits well above the recent used EUR comp set, which centers around €1,673 and tops out at €1,962 at the 75th percentile, so this is clearly ambitious rather than fair.

That said, the SR-009 remains a landmark electrostatic: extremely fast, open, and resolving, with superb treble air and precision imaging when paired with a proper Stax energizer. It’s still a serious endgame headphone for the right system, but at this money the listing really needs to justify itself with excellent condition, low hours, and complete accessories; otherwise a buyer should expect more product for the price.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About 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.
