This is a stereo power amplifier of the Laboratory Series that was developed through repeated trial listening with an emphasis on listening feeling in pursuit of ideal operation when mounting speakers.rnrnPower Cascode Super A circuit (PAT. PEND.) is adopted for the circuit system.rnThis circuit utilizes the characteristics of a transistor, which is originally a current amplifier, to solve the difference in operation between a pure resistance load and a speaker load. The output transistor always operates at a constant voltage, and only the current changes according to the signal. Therefore, th... read more
