A premain amplifier that introduced the technology of 1-bit amplifiers in total. A 1-bit amplifier converts an analog signal into a DSD signal and becomes a digital amplifier that amplifies the DSD signal as it is. Although it is a special amplifier, its accuracy and large amount of information are what sets it apart from poor analog amplifiers and digital amplifiers of PWM. Serial OB5081 (Mizushima Itsuro)
