180W/ch INTEGRATED STEREO AMPLIFIER

The E-4000 integrated amplifier has emerged from separate amplifier technologies. The preamplifier section features AAVA using ANCC to allow for volume adjustments that maintain high levels of vibrancy. The power amp section employs balanced transmission utilizing the instrumentation amplifier principle to drive noise suppression to its limit. 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 last ounce of potential from the speakers and create soundscapes filled with subtlety.

The E-4000 is the mid-tier of Accuphase's E-series — 180 W per channel Class A/B with the ANCC-equipped AAVA volume control and a 4-fold parallel push-pull output stage. It sits between the entry-tier E-3000 (100 W) and the higher E-5000 (240 W); customers who want pure Class A operation at this price-class should consider the E-700 instead.

• Revolutionary AAVA volume control
