Accuphase E-6000 Integrated Amplifier

The E-6000 has the highest output power in the Accuphase integrated amplifier line-up. The impressive power produced by the six-fold parallel push-pull configuration with power transistors driven in Class AB easily drives even very large speakers. The Preamplifier Section features a Balanced AAVA type volume control that implements ANCC to create ideal volume adjustment. AAVA sets the listening level; ANCC reduces unwanted noise and distortion within that volume-control circuitry. AAVA: Accuphase Analog Vari-gain Amplifier AAVA adjusts volume by varying amplification rather than attenuating the music signal through a conventional variable-resistor volume control. It converts the incoming voltage signal into multiple current signals with different weightings, selects a combination appropriate to the desired volume, and converts the combined current back into a voltage signal. The audio processing remains analog. The “Balanced” designation refers to implementing AAVA in a balanced circuit configuration. The purpose is precise level adjustment with low noise, while avoiding the changing impedance and mechanical signal-contact issues associated with conventional potentiometer-based volume controls.accuphase+1 ANCC: Accuphase Noise and distortion Canceling Circuit ANCC uses a secondary, low-noise amplifier to cancel noise and distortion generated by the main amplifier within the relevant circuit stage. In this volume-control application, it operates in AAVA’s current-to-voltage—or I/V—conversion amplifier. Accuphase describes its benefit as improved noise performance, particularly at low to typical listening-volume settings.accuphase+1 The distinction is function: AAVA sets the listening level; ANCC reduces unwanted noise and distortion within that volume-control circuitry. “Ideal volume adjustment” is Accuphase’s description of the intended result, not a claim that the circuit is literally free of all noise or distortion.
