Sansui stereo control amplifier C-2102

Description

Description:

The Sansui C-2102 is a high-quality stereo control amplifier (preamplifier) from the 1980s, known for its excellent sonic performance, comprehensive controls, and versatile input/output options. It was positioned as a premium component, aiming to compete with high-end offerings of the time. A notable feature is its dual phono input section, capable of handling both Moving Magnet (MM) and Moving Coil (MC) cartridges, including a dedicated high-output MC setting. The C-2102 also includes a semi-parametric equalizer for fine-tuning the audio, along with loudness and subsonic filter controls. Its design emphasizes clean signal paths and low noise for accurate audio reproduction.
