Offered is „SRM 500T Kopfhörerverstärker“ by STAX as new device from the category „Headphone Amplifier“ on audio-markt.de - the online market place for high-end. The advert with the number 3441425094 ends on 22.12.2026 at 18:03 o'clock.
At €1,399, this is a strong deal rather than merely fair value. Your comparable used listings place the market’s 25th percentile at €2,043, with a €3,091 median, so this example is €644 below even the lower quartile—assuming it is complete, functional, and correctly described.
The SRM-500T is a particularly appealing Stax driver for owners of Pro-bias electrostatic headphones: its FET input and 6FQ7/6CG7 tube output stage offer a distinctive hybrid presentation, while balanced and RCA inputs add useful system flexibility. It supplies the required 580 V bias and has enough output for the Stax range, making it a sensible step up from entry-level energizers. Check that both tubes are healthy, the two Stax outputs work, and the correct power cable and original packaging are included, but at this price those are verification points—not reasons to pass.

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.
