This is a fair ask: £925 sits exactly at the median of three recent comparable listings, with the observed market spanning roughly £678 to £1,105. It is neither a bargain nor an ambitious premium, but a reasonable market-level price if the unit is working properly and cosmetically sound.
The SRM-007t remains a highly regarded Stax energiser, valued for its refined, spacious presentation and strong pairing with Lambda and Omega-era earspeakers. Its tube output stage gives the system a more substantial, nuanced character than many basic Stax amplifiers, making it a worthwhile foundation for a serious electrostatic setup. At this price, condition, service history, and the inclusion of the original power lead and packaging matter more than small cosmetic marks; a clean, tested example would be an easy price to justify.

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.
