Stax SR-009 Headphones Boxed Excellent and boxed.
The Stax SR-009 remains a pinnacle of electrostatic headphones, delivering unmatched transparency and airiness that few rivals touch in the high-end lineup. At £1,900 in good condition, this asking price sits squarely in the fair zone—right at the median of £1,867 from four recent comparable GBP listings (25th percentile £1,706, 75th £1,948). It's neither a steal nor overreach for a well-kept used pair in today's market.
Before biting, verify the ear pads and diaphragm integrity, as these are prone to degradation after 5-7 years and can cost £200+ to replace. Confirm the original serial-matched XLR-4 cable and PSU are included, ideally with service history to rule out static buildup or arc failures common in older units. Test for even soundstaging on your rig.
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.
