• Adopting the principle of audio special integrated circuit and transistor current amplifier circuit, the sound performance is clear, thick and strong;

• The precision stabilized power supply is composed of two important components: transistor and stabilized integrated circuit, with extremely high voltage stability and extremely low AC ripple;

• The power transformer is a square transformer, which has the advantages of small size and bold tone;

• This machine uses a large number of German WIMA and Japanese NICHICON brand special audio capacitors, no matter the sound quality, tone color and sound field have excellent performance.

• The large volume control potentiometer is the Japanese ALPS brand, which is reliable and durable, low noise, good tone, and small two-channel error.

• There is a GAIN button on the panel, which can select different levels of signal sources and earphone impedance to obtain the best hearing effect;

• USB can decode the highest PCM 32bit/384kHz digital signal source output from the PC (computer).

• OPT/COA (optical/coaxial) can decode PCM 24bit/192kHz format digital signal source.
