The evolution of preamplifiers in the history of volume control. Accuphase has addressed the issue of variable resistance with our original AAVA technology, which evolved into Balanced AAVA, and later became Dual Balanced AAVA. The Dual Balanced AAVA with ANCC installed in the C-3900S represents circuitry technology that achieves the ultimate in volume control. The C-3900S is a premium preamplifier for breathing life into deeply emotional performances and songs.
