Accuphase E-4000 Integrated Amplifier
Class AB integrated amplifier offering 180 watts per channel into 8 ohms with exceptional clarity, control, and Accuphase musical refinement.
The Accuphase E-4000 Integrated Amplifier represents a new generation of Accuphase engineering, blending advanced separate-amplifier technology into one luxurious chassis. Delivering 180 watts per channel into 8 ohms and 260 watts per channel into 4 ohms, the E-4000 delivers effortless dynamics, superb transparency, and commanding authority over any loudspeaker.
The Accuphase E-4000 employs the renowned AAVA (Analog Vari-gain Amplifier) volume control system for precise level adjustment without degrading signal quality. Its ANCC (Noise and Distortion Canceling Circuit) reduces noise by approximately 20 percent compared to earlier designs, ensuring ultra-pure, distortion-free reproduction.
A fourfold parallel push-pull output stage operating in Class AB guarantees powerful current delivery with fine musical detail. A massive toroidal transformer and high-capacity filter capacitors support rock-solid performance, while the damping factor of 800 ensures tight, controlled bass and stable drive.
Connectivity options include both balanced XLR and unbalanced RCA inputs, along with pre-out and main-in terminals for system integration. The E-4000 also includes two expansion slots for optional Accuphase boards, such as the DAC-60 digital input module or AD-60 phono stage, allowing flexible system growth.
Built with Accuphase’s hallmark craftsmanship, the E-4000 combines stunning build quality, refined ergonomics, and long-term reliability that make it a true reference in integrated amplification.
