US$300 looks like a strong buy for an HCA-2 if it’s fully working and reasonably complete. That sits well below the typical used territory for this amp, which has often traded in the upper hundreds and can still show up around US$335 even with a channel problem, so a clean one at US$300 is very attractive.
The appeal is easy to understand: the HCA-2 is a respected 150Wpc design with a clean, quick, controlled presentation and enough current to make many speakers wake up. It’s especially nice for someone wanting a serious-sounding, compact stereo amp without spending big money. Main thing to verify is basic health and originality—power-up behavior, channel balance, and whether it has the right accessories—because at this age a bargain depends on it being genuinely functional.
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.
