PS Audio’s Stellar S300 sits in that sweet spot of compact, serious solid-state power: respected, straightforward, and easy to place in a real system. At £625, this is a strong deal versus your recent used comps, sitting below the £727 25th percentile and well under the £803 median, so it reads as a bargain rather than a merely fair ask.
That makes it attractive for buyers who want clean, controlled power with good bass grip and an unfussy presentation rather than a flashy statement amp. The upside here is simple: you’re getting a well-regarded stereo power amp at a price that leaves room for shipping or a future service cushion, and if the unit is tidy and complete, it’s the kind of listing worth moving on quickly.

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.
