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
At A$2,950, this asking price sits right near the typical median for a used PS Audio P3 Stellar PowerPlant 3, making it a fair but not bargain deal. New units retail around A$3,400–A$3,600, and verified used listings often range from A$2,600 to A$3,200, so this price is squarely in the middle of that band.
The P3 is well-regarded as PS Audio’s most affordable AC regenerator, delivering clean, voltage-stable power with 300W continuous regenerated output and excellent noise suppression—ideal for small to medium, power-hungry systems. Its compact design, robust filtering (over 60 high-end caps), and sound-quality benefits make it a worthwhile upgrade for audiophiles seeking measurable power improvements. At a fair price with a clean listing, this is a solid buying opportunity for those ready to invest in cleaner mains power.

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.
