The Accuphase E-3000 integrated amplifier emerged from the path forged by the technologies used in high-end equipment. Among this amplifier’s constituent elements, the vitally important volume control circuits incorporate AAVA that employs the ANCC principle. The power amplifier section produces balanced signals relying on the instrumentation amplifier principle while simultaneously creating a robust output stage through three-fold parallel push-pull power transistors driven in class AB. Every moment spent immersed in the vibrant playback of the Accuphase E-3000 is one to relish.
