At £6,187, this listing sits just above the 75th percentile (£6,040) of the grounded market data, making the price ambitious but not unreasonable for a flagship Class A unit. While it exceeds the median (£5,896) by roughly £300, it remains well below the original retail price of £10,600, offering significant value for a high-performance amplifier that still holds its generation’s top-tier status.
The Accuphase E-650 is revered for its ultra-low noise, super-high damping factor (800 guaranteed), and pure Class A operation that delivers 30W into 8Ω with smooth power expansion into lower impedances. As the only Class A integrated in Accuphase’s lineup since 2017, it pairs effortlessly with most speakers and offers rare, original-owner integrity when clean. With no known failure points specific to this model and included optional boards adding value, this is a compelling buy for enthusiasts seeking flagship performance at a fair used price.

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.
