• Adopt dual mono full balanced amplifier circuit design, two channels are completely independent; in order to reduce dynamic crosstalk interference, each channel uses a power transformer, and a special transformer shielding box eliminates power noise interference.

• The core of the amplifier part is a high-speed DC amplifier module chip developed for many years of experience, with wide frequency response, extremely low distortion, and slender and thick sound performance;

• The volume controller is a Japanese-made ALPS large quadruple high-precision potential It has small channel error, long life, and beautiful sound performance;

• The output stage is composed of FETs to form a Class A output device, which can easily drive the post-amplifier;

• Use MKP audio special film electrodeless capacitor, 1% high precision metal film Resistance, parallel regulated power supply;
