Angeboten wird „STAX SRM-700s HEADPHONE AMPLIFIER BLACK AS NEW“ von STAX als Gebrauchtgerät aus der Kategorie „Kopfhörerverstärker“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 4718483838 endet am 16.07.2026 um 16:31 Uhr.
The Stax SRM-1 is a legendary, pure class-A electrostatic amplifier from the 1980s, revered for its DC-coupled, FET-input design that delivers warm, transparent sound. At €2,950, this asking price is ambitious, sitting well above the 75th percentile of €1,786 from our ground truth data on recent EUR listings, where the median is only €1,327. While external sources suggest typical used values range from €400 to €700 (roughly $500–$700), the listed price significantly exceeds even the upper bound of that market, making it a tough benchmark unless the unit is modified or in pristine original-owner condition.
That premium is only worthwhile if the amplifier includes original accessories, the box, manual, or meaningful mods like capacitor upgrades, which can enhance its legendary tonal balance. If this is a clean, unmodified unit, the price feels steep compared to fair market values; however, if it’s a rare, fully serviced example with original Lambda Pro headphones, it could represent a justified opportunity for a dedicated Stax collector. Without such extras, buyers should weigh whether the vintage charm and sound justify the cost over more affordable alternatives.

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.
