At US$295, this sits just under the US$300 median and below the US$300 25th percentile, so it reads as a solid buy rather than a stretch.
The SRM-1 is a respected Stax energizer for getting into or back into electrostatics, with the kind of clean, quick presentation that keeps it relevant long after newer gear appears. At this price, the appeal is value and usability: if it powers up cleanly and hasn’t been abused, it’s a very sensible way to support a Stax setup without paying top-of-market money. Since condition is unknown, the main thing to confirm is basic function, quiet operation, and that it’s complete enough for immediate use; otherwise, this is the sort of listing that rewards a fast decision.
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.
