The PS Audio Stellar M700 is a formidable Class D monoblock known for delivering massive power and high-end control. At US$2,199, this listing sits just above the 75th percentile of US$2,123, making the price slightly ambitious rather than a bargain, though it remains close to the fair median of US$2,047.
This amplifier is well-regarded for its 350W into 8 ohms output and ultra-linear ICE module design, offering a robust foundation for high-end systems. Since the price is near the top of the typical used range, it is a worthwhile buy only if the condition is pristine, it is original-owner stock, or accessories are included. A clean listing of this powerful, neutral-sounding amp at this price point represents a solid buying opportunity for those seeking serious power without entering the ultra-luxury tier.
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.
