Accuphase c-200S Stereo Control Center

Accuphase Laboratory, Inc. (known initially as Kensonic Laboratory, Inc.) is a Japanese, Yokohama-based high-end audio equipment manufacturer founded by former Kenwood engineer Jiro Kasuga in late 1972.

The Accuphase c-200S Stereo Control Center is a vintage pre-amp made to pair with the Accuphase P-300S Stereo Power Amplifier or Accuphase Monophonic Power Amplifier M-60 that we have pre-owned here in Audio Image ourselves.
