Offered is „SRM-1/MK-2 Professional (Pro) Kopfhörerverstärker“ by STAX as second-hand device from the category „Headphone Amplifier“ on audio-markt.de - the online market place for high-end. The advert with the number 818731955 ends on 14.12.2026 at 13:44 o'clock.
€429 is a fair asking price for a Stax SRM-1, sitting just above the €422 median and comfortably within the recent €389–€1,087 market spread.
This is a worthwhile buy for anyone building a classic Stax system: the SRM-1 is a capable, discrete, clean-sounding energizer with both Normal and Professional bias outputs on the relevant versions, making it compatible with a broad range of Stax earspeakers. At this price, condition matters more than chasing a bargain—confirm both channels are quiet and balanced, the correct output socket is present for your headphones, and there is no hum, crackle, or evidence of neglected storage. If it checks out electrically, €429 is sensible rather than inflated.
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.
