• Use electronic tube audio output, effectively eliminate the digital sound of the CD player, make the sound beautiful, analytical, airy, and better sound field positioning;

• Electron tube and transistor hybrid high-voltage regulated power supply, with extremely high voltage stability. The AC ripple coefficient is extremely low, and the sound performance is more "guts";

• Using Sanyo high-performance movement, coupled with highly integrated CD7-II digital servo IC, so that this machine has the advantages of accurate reading, strong error correction ability, and good shock resistance.

• The digital and analog conversion chip is the decoding chip PCM1796 of Burr-Brown Company in the United States. The chip has 24bit conversion accuracy and 192KHz sampling frequency;

• The analog signal is amplified using Burr-Brown's high-precision, high-speed operational amplifier OPA2134 and JRC5532; at the same time, it is equipped with a third-order GIC low-pass filter to effectively filter out the interference noise of the digital signal; 

• The power supply adopts high-flux, low-leakage toroidal transformer to supply power, thereby effectively reducing magnetic field interference;

• The low-voltage analog power supply is powered by a stabilized power supply, and the digital and movement power supplies are also supplied by independent stabilized power supplies to ensure that each part of the circuit does not interfere with each other
