Should you consider US$166 a strong deal for this Stax SRD-6? Absolutely, because typical used pricing for this amp alone sits between US$25 and US$100, making your asking price a clear bargain compared to the median market. While some rare complete sets with original headphones appear higher, the amplifier itself rarely exceeds US$100, so securing it at US$166 is an excellent entry point for vintage Stax systems.
This SRD-6 is well-regarded for its warm, natural sound that pairs beautifully with classic Stax electrostatic headphones like the SR-5, offering a timeless listening experience that modern units sometimes lack. Its meaningful upside includes original-owner condition, a 30-point service history if available, and the rarity of finding a fully functional vintage Stax amp at this price. With no common failure points mentioned for this specific listing, it represents a genuine buying opportunity for enthusiasts seeking authentic vintage hi-fi.

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.
