• The core of the amplifying part is the DC combined gallstone hybrid amplifier circuit developed for many years of experience, which will make you experience the mixed sound of gallstones;


• Using dual mono full balanced amplifier circuit design, the two channels are completely independent; in order to reduce Small dynamic crosstalk interference, each channel uses a power transformer, and a transformer shielding box is made to eliminate power noise interference;


• Eight imported audiophile-grade ECC88/6DJ8/6922 electronic tubes and fully gold-plated tube sockets, the sound performance is obviously beyond ordinary Products;


• The electronic tube class A output buffer with up to 30V undistorted output voltage can easily match many post-amplifiers;


• The volume controller is a large-scale quadruple high-precision potentiometer made in Japan, ALPS, with small channel error, long life and ensuring The sound is beautiful; the remote control volume system is added to make users feel more convenient;


• A large number of audio components are used in the machine, such as the use of MKP audio special film electrodeless capacitors, 1% high-precision metal film resistors, and parallel stabilized power supplies to make the sound Reach the best level.
