Unknown condition at US$300 lands right on the median of recent comps, so this reads as a fair ask, not a bargain and not ambitious. With the 25th percentile also at US$300 and the 75th at US$317, there’s basically no pricing cushion here; I’d treat it as market-clearing only if the unit is genuinely clean and working.
That still makes sense for a Stax SRM-1, which is a respected electrostatic energizer with a straightforward, no-frills presentation and a reputation for getting the most out of classic Stax earspeakers. The upside is in condition and completeness: if it’s original, quiet, and comes with the right power setup and any needed adapters, this is a sensible buy; if service history is unknown, I’d want confirmation on output stability, channel balance, and any hiss or crackle before paying full US$300.
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.
