Accuphase C-57 Stereo Phono Amplifier

The C-57’s configuration provides a fully balanced phono equalizer from input to output. The combination of a high precision equalizer amplifier and a dedicated MC/MM head amplifier fully optimized for the cartridge characteristics creates a highly accurate phono equalizer. As a first, the MC head amplifier uses ANCC to further improve noise performance. Dedicated MC phono balanced inputs allow for balanced connections with record players. The C-57 combines only the best technological advances to extract the full potential of analog discs.
