Commentary
This stereo power amplifier was developed as an answer to the question of how much sound quality can be refined while maintaining a high output that can drive all kinds of speakers.
The power supply employs a large toroidal transformer with a capacity of 1.2 kva per channel and a large-capacity capacitor, realizing the capability of sending 45 v pulses at a high current of 30A per channel at peak.
The interior is completely monaural construction, and high precision parts are carefully selected for use.
Especially, very thick pure copper cables are used for internal wiring.
The damping factor can be switched to 3 levels of NOM/LOW/HIGH by the switch on the rear panel, further enhancing the adaptability to speakers.
