Accuphase E-4000 Integrated Stereo Amplifier

The E-4000 integrated amplifier has been developed from various separate amplifier technologies. Its preamplifier section features AAVA technology combined with ANCC, allowing for volume adjustments that preserve a high level of vibrancy. The power amplifier section employs balanced transmission, utilizing the instrumentation amplifier principle to achieve maximum noise suppression. The E-4000 is equipped with a four-fold parallel push-pull configuration of power transistors, driven in Class AB in the output stage, to extract every bit of potential from the speakers and create soundscapes rich in subtlety.
