Offered is „SRM-700S High-End 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 3801582144 ends on 27.10.2026 at 06:24 o'clock.
The timing is solid here: this is a current-generation Stax energizer, so you are not buying into an obsolete platform. At €2,699, it sits well above the €1,786 median and also above the €2,994 75th percentile? No — it is just below that upper quartile, so this is ambitious but not crazy for a clean example in good condition.
What makes it worthwhile is the usual Stax appeal: very low-noise, fast, transparent drive for electrostatic headphones, with enough authority to let the SR-X00 series really open up. For a buyer pairing it with existing Stax earspeakers, the upside is strong if the unit is tidy, complete, and recently checked. At this level, I’d want confirmation of original packaging, cables, and that it has been tested properly, but a good-condition unit like this is still a respectable pick rather than a red flag.
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.
