A stereo power amplifier that pursues both functionality and sound quality.

The input circuit uses a dual-FET balanced bridge differential input method, and the driver stage uses a complimentary service cascade connection to improve the drive capability of the bipolar transistor to the Darlington power stage.
In addition, we have achieved high stability by optimizing feedback at each stage and minimizing overall feedback.

It can also be used as a monaural power amplifier by bridge connection.
