The E-4000 is a succession model of E-480, the 12th generation Accuphase Class-AB high-power integrated stereo amplifier. The Preamplifier section provides a low-noise AAVA volume control with a fully refined circuit configuration and layout. The Power amplifier section adopted the bipolar transistors in a four-fold parallel push-pull arrangement and made a significant achievement for the driving ability of loudspeakers. The E-4000 extracts the full potential of any loudspeaker to reproduce sound overflowing with energy and vividness.

E-4000 has a mono-block construction. A strong power supply with a massive, specially-made, high-efficiency toroidal transformer and 40000μF filtering capacitors are installed in the unit's center. In addition, the two power amplifier modules are kept separate for the left and right channels. The AAVA module is set at the front of the unit to avoid noise interference.

The E-4000 has the second highest output power in Accuphase integrated amplifiers, and the rated continuous average output power is 180W/8Ω. The E-4000 perfectly drives any loudspeakers, even lowefficiency ones.

AAVA (Accuphase Analog Vari-gain Amplifier) is a volume control principle that eliminates all variable resistors from the signal path. This AAVA volume control is Accuphase's unique technology. The E-4000's AAVA module contains six paralleled buffer amplifiers and the lower-impedance V to I converter and utilizes the ANCC, so the E-4000 achieved 20% lower noise than the E-480. *E-480's AAVA module has no ANCC and five circuits paralleled in the buffer amplifier.
