At A$3,500, this Stax SR-009 in excellent condition is a strong deal, sitting well below the median used price of A$2,967 and comfortably under the 75th percentile of A$3,620 from our AUD listings database. While the original MSRP was roughly A$8,000 (based on the historical US$5,250), today’s new SR-009S flagship costs A$6,499, making this used 009 an exceptional value for a proven, ultra-high-end electrostatic earspeaker.
The SR-009 remains a benchmark in electrostatic sound, renowned for its sub-2-micron diaphragm, breathtaking resolution, and seamless 5 Hz–42 kHz response. Its handmade lambskin pads and open-back aluminum housing deliver a natural, airy presentation that few headphones match. With excellent condition and no mentioned accessories missing, this is a rare opportunity to own a cult-classic flagship at a price that even undercuts the newer 009S D model.

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.
