This is a buyer’s market for this piece of kit: at US$450, it lands below the US$475 25th percentile and well under the US$562 median of the recent comparable listings, so it reads as a strong deal rather than a merely fair one. For a used integrated amp, that puts the asking price on the right side of the market without needing a lot of negotiation.
The appeal is straightforward: the Sprout 100 is well-liked for packing a genuinely useful all-in-one layout into a compact box, with a sound that has long been appreciated for easy musicality and practical day-to-day flexibility. At this price, the upside is good if it’s complete and working cleanly; I’d mainly want confirmation of function, included power supply, and any original accessories, since those matter more to resale than cosmetic nicks on a piece like this.
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.
