This is a seller’s market for premium integrated amplifiers, but this particular asking price is ambitious: US$10,499 sits well above the recent comparable median of US$8,079 and the 75th percentile of US$8,902. It is roughly US$1,600 above the upper-quartile reference, so the seller needs an unusually strong example to justify it.
The E-4000 is a serious, highly capable amplifier, combining 180 watts per channel into 8 ohms, excellent speaker control, balanced connectivity, and Accuphase’s refined AAVA volume system. It is prized for clean, powerful, nuanced sound and unusually comprehensive usability. Still, with condition listed only as unknown, this is not a buying opportunity at US$10,499; original packaging, remote, documentation, spotless cosmetics, service history, and a strong warranty would be needed before considering a substantial premium.
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.
