Best choice: Accuphase C-2410
by uksoundbase.com
The C-2410 preamplifier inherits the superb design technology of the C-2810, including the improved AAVA (Accuphase Analog Vari-gain Amplifier) volume control with similar specs and configuration. AAVA is a revolutionary concept that takes a radically different approach from conventional volume controls. The result is high performance and sound quality far exceeding conventional designs.
The main features of this preamplifier are:
Logic-controlled relays assure high sound quality and long-term reliability
EXT PRE function allows use of external preamplifier.
