Characteristics:

1. With USB input

2. Serve circuit is provided with Phillip SAA 7824 chip.

3. CS4398 D/A switch box is used.

4. OPA2604 is used as high quality filter circuit to thoroughly remove digital signal and resume the original music signal.

5. It is provided with high class RUBY vacuum tube (2 x 12AU7) analogue amplifier circuit, for excellent reproduction.

6. Top level ERSE capacitor is used as vacuum tube coupling.

7. Eight groups of independent voltage regulators are used for power supply, with little interference, strong driving power and rich music details.

8. With coaxial and optical fiber digital signal output of one group respectively, RCA and balance audio signal output of one group respectively.

9. Top level WIMA capacitor is used as the LC filter circuit of power supply, to purify power sup;y and make the background of music clearer.

10. The vacuum tube is preheated and stabilized for twenty minutes before entering the operation mode after the player is turned on.

11. Its excellent up frequency treatment brings the 44.1KHz sampling frequency of CD signal to 88.2KHz or 176KHz, to make the reproduce audio signal closer to the original analogue signal, to thoroughly remove digital sound and produce a tone effect comparative to LP analogue player.
