At US$2,800, this sits a touch above the recent used median of US$2,714 and just over the 75th percentile of US$2,757, so it reads as a mild premium rather than a bargain. That said, for a current-production electrostatic energizer of this caliber, it is still in the zone where a clean, complete example can make sense if you want the platform now.
The appeal here is straightforward: the SRM-700T is a respected tube/hybrid driver with the kind of authority, refinement, and speed that Stax owners buy into the brand for. The included cables and accessories add real value, and if the unit is well cared for, that narrows the gap between “fair” and “worth it.” At this price, the main thing to verify is simply that everything powers up cleanly and the package is truly complete; otherwise, it’s a solid but not exceptional buy.
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.
