PS Audio P3 Stellar Power Plant Power Conditioner Power Plants are regarded for their ability to reduce noise and THD to virtually zero while providing rock steady voltage output. Traditional power conditioners can only affect a portion of incoming noise and are unable to compensate for over or under voltage. Furthermore, power conditioners raise the impedance of the power going to your system, which can bleach your sound and drain away dynamics. The P3 handles things completely differently. Through the P3’s active regeneration process, it is able to provide perfect power while also lowering t
A used Stellar phono stage at A$2,500 is fair to slightly firm, not a bargain. New pricing has sat around A$4,100–A$4,900 in Australia depending on the source and version, while used examples overseas have turned up around A$2,700 equivalent, so this ask is close to the middle of the realistic used band rather than a standout deal.
It’s well regarded because it’s a seriously flexible MM/MC phono stage with remote-controlled loading and gain, low noise, and enough resolution to make good cartridges shine. If the unit is clean, complete, and from a careful owner, it’s a solid buy for someone who wants one phono stage to cover a serious vinyl setup; at this price, I’d mainly want confirmation of the remote, original packaging, and that it’s been working quietly with no channel issues.

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.
