Accuphase C-57 Stereo Phono Amplifier

For anyone serious about vinyl, the C-57 is a dedicated phono stage designed to get everything possible out of a good cartridge.

It runs a fully balanced signal path from input to output, and pairs a high-precision equalizer amplifier with a dedicated MC/MM head amp that uses Accuphase's ANCC noise-cancelling technology for an especially quiet result. With a balanced MC input plus three more standard phono inputs and adjustable load impedance for a wide range of cartridges, it's built to be the long-term analog front end of a system.
