At A$3,640, this PS Audio Model One power amplifier sits just under the 75th percentile (A$3,649) of 72 recent AUD used listings, making it an ambitious but not unreasonable price for a fair-condition unit. It is not a bargain—those would be near or below A$755—but it’s a solid ask for a collector’s piece that’s rarely seen. For a fellow enthusiast, this is a fair-market entry into PS Audio’s historic first amplifier, released in 1975 with 70 watts per channel and a reputation for clean, musical sound.
The Model One is well-regarded for its vintage tonal character and original-owner charm, offering genuine audiophile history in a compact, 70-watt design. Its timing as a rare find from the brand’s debut era adds meaningful upside, especially if the listing includes original accessories or documentation. At this price, it’s a buying opportunity for someone chasing legacy gear, not a deal, but a worthwhile investment in PS Audio’s foundational legacy.

PS Audio, a pioneering American hi-fi brand, traces its roots to 1973 when co-founder Paul McGowan launched the company in California alongside Stan Warren. Emerging from the analog golden age, it debuted with a standalone phono preamplifier, reflecting McGowan's early passion for vinyl playback honed through radio station connections and encounters with audio enthusiasts. The brand quickly evolved, embracing digital audio in the 1980s by releasing one of the first high-end CD players, the PS Audio CD-1, soon after Philips and Sony introduced the format.
Today, PS Audio specializes in premium electronics, including power amplifiers, preamplifiers, digital-to-analog converters (DACs), and integrated amplifiers, with a hallmark focus on power conditioning via innovative AC regenerators known as Power Plants. These devices, born from Stan Warren's mid-1980s discovery that oversized transformers enhance audio performance, remain a cornerstone. The lineup also encompasses digital lenses for refining streaming and disc playback, alongside select analog components, though it eschews speakers, headphones, turntables, or cables.
Positioned firmly in the high-end market, PS Audio commands respect among discerning audiophiles for its bold engineering and unwavering pursuit of musical purity. Celebrating 50 years in 2023, it occupies a niche as an innovator rather than a mass-market player, appealing to buyers who prioritize transformative power delivery and digital refinement in sophisticated systems.
