This is a buyer’s market for this category at this price. At US$2,200, it sits essentially at the US$2,199 median and just above the US$2,200 75th percentile, so it reads as fair to slightly firm, not a bargain and not meaningfully overpriced.
What makes it appealing is the core M700 package: a compact, high-power monoblock with a strong reputation for control, grip, and easy drive on difficult speakers, plus balanced and single-ended inputs and real 4-ohm/2-ohm muscle. If the pair is clean, properly functioning, and complete, it’s a sensible buy for someone wanting serious power without moving into giant-class amp territory. Since condition is listed as unknown, I’d verify channel balance, noise, protection behavior, and whether you’re getting one amp or a matched pair before committing.
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.
