Is A$800 a bargain for a complete Stax SRS-3100 system, or just a fair used price? At A$800, this listing is a strong deal compared to the typical used market, where the system often trades between A$1,100 and A$1,400 depending on included accessories and region. New pricing data from Japan and the US suggests the SRS-3100 retails around A$1,350–A$1,700 today, making this asking price roughly 40% below new and well under the median used value.
The SRS-3100 is well-regarded for its excellent electrostatic clarity and the smooth, refined sound of the SR-L300 ear speakers, paired with the SRM-252S energizer that delivers clean, stable bias voltage. This system offers a genuine entry into high-end Stax electrostatics without the cost of flagship models, and if it includes the original cable and box, the upside is even greater. At A$800 in excellent condition, this is a buying opportunity for anyone seeking Stax performance without the usual premium.

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.
