Buyer’s market here, and US$2,999 looks fair-to-good for a PS-510 if it’s genuinely complete and working properly. Accuphase’s U.S. list pricing is still premium, and this model is an active AC regenerator rather than a simple strip-style conditioner, so used pricing tends to stay firm; at this level I’d view it as sensible rather than cheap.
What makes it worth a look is the PS-510’s reputation for delivering a very clean, regulated AC supply up to 510 VA, with onboard metering and a real, audible benefit in quieter systems where source gear and low-to-moderate draw components matter most. It’s a strong buy if the included cables/accessories are original and the unit has a clean service history; at this price, I’d mainly verify that it powers up cleanly, the meter behaves normally, and there’s no sign it’s been pushed hard or modified.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Accuphase Laboratory, Inc., founded in 1972 in Tokyo by brothers Nakaichi and Jiro Kasuga, emerged from their departure from Trio-Kenwood, the company they had co-established decades earlier. Dissatisfied with mass-production compromises, the Kasugas formed Kensonic Laboratories—later renamed Accuphase Laboratory—and relocated to Yokohama in 1973. The brand name, blending "accurate" and "phase," reflected their commitment to precision audio reproduction amid the 1970s hi-fi boom. Their debut products, the P-300 power amplifier, C-200 preamplifier, and T-100 tuner, immediately earned acclaim, including Japan's Compo Grand Prix for the P-300.
Accuphase specializes in high-end electronics, renowned for integrated and power amplifiers, preamplifiers, tuners, CD players, and digital sources like DACs. While their core strength lies in meticulously engineered amplifiers celebrated for phase accuracy and reliability, the lineup extends to digital components, mains filters, and room correction units. Hand-assembled in Yokohama with top-tier parts and innovative circuits, these products prioritize sound purity over volume, eschewing speakers, turntables, headphones, or cables.
Positioned firmly in the ultra-premium high-end market, Accuphase commands reverence among audiophiles for its timeless build quality, engineering excellence, and enduring performance. Synonymous with Japanese hi-fi mastery, it stands as a reference benchmark, appealing to discerning buyers seeking components that deliver uncompromised musical fidelity and last for generations.
