The E-4000 is an integrated amplifier that inherits the technology cultivated in separate amplifiers.

The preamplifier section is equipped with "AAVA" that uses "ANCC", and adjusts the volume with high freshness.

The power amplifier section uses an "instrumentation amplifier" that achieves balanced transmission and maximizes noise performance.

The E-4000, which has an output stage with "4 parallel push-pull class AB operation of power transistors", fully draws out the potential of the speakers and reproduces a fascinating sound stage.
