At US$999, this PS Audio Stellar S300 is a genuine bargain, sitting well below the used-market 25th percentile of US$1,042 and far under the median of US$1,276. The listing’s condition note (described as “unknown” in the prompt) implies you should verify physical state, but if it’s clean, the price is an exceptional deal for a well-regarded dual-mono Class D amplifier that delivers 140W into 8Ω and 300W into 4Ω with modern ICE module performance.
This amplifier is prized for its musicality, compact footprint, and ability to drive harder speakers thanks to its fully balanced, low-crosstalk design. It’s PS Audio’s entry-level two-channel power amp, yet it holds strong resale value and offers serious upside for buyers upgrading from receivers or integrateds. If the unit includes original boxes (as one prior seller noted) and shows no wear, this is a clear buying opportunity—not a risk.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
