Commentary
This amplifier is a direct drive amplifier system that is responsible for all control.
The low-impedance output design of 10 Ω, enough to extend the audio cable from the preamp to the power amplifier, helps the power amplifier drive the speakers directly.
Two sets of ICL type equalizer amplifier for MM cartridge and MC cartridge are built in the input.
Unlike head amplifiers and step-up transformers, switches and input capacitors are not inserted into the microsignal path, so the purity of sound is enhanced.
