ccuphase’s ground-breaking AAVA (Accuphase Analog Vari-gain Amplifier) volume control, first introduced in the model C-2800, has been continually further refined and improved. AAVA operates fully in the analog domain, but it eliminates all potentiometers from the signal path. This has a number of advantages, such as (1) outstanding SN ratio, (2) extremely low distortion, (3) virtually no change in frequency response and sound quality at any listening level, (4) minimal leftright level differences (tracking errors), and (5) minimal leftright crosstalk. The result is a volume control that far surpasses conventional concepts.
