Are you looking for a preamp, or a complete control amplifier? At US$900, this looks like a strong deal if the unit is fully functional and includes its remote. The GCC-100 originally sold for roughly US$2,795, and its unusual combination of preamp functionality, 100 watts per channel, and flexible Gain Cell volume control still makes it unusually capable for the money. A precise current used-market percentile is difficult to establish, but US$900 is comfortably in bargain territory rather than an ambitious ask.
Its appeal is real: the design is fully balanced, exceptionally quiet, transparent, dynamically strong, and can drive difficult speakers better than many conventional integrated amplifiers. It can also serve as a line-level preamp through its auxiliary output or function in a home-theater system via bypass. Check that the display, buttons, remote, inputs, and speaker terminals all work, and confirm the original remote is present; otherwise, this is a very worthwhile vintage PS Audio buy.

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.
