Product Details




1.  Single-threaded ultra-real-time code is used to ensure the pure sound and more restored details .

2.  Rewrite the code to fully read the card and isolate the TF power supply. The sound background is purer

and more natural.

3. The 3.0.088ps dual femtosecond crystal oscillator provides the clock for the global synchronization of the

whole machine.

4. Two 470000uF super-capacitors provide independent power for analog and digital.

5.  Six pieces of OPA1622 realizes four thrust modes of amp: standard, high current, high voltage, double


6. AK4495SEQ sound quality special edition + high voltage power supply, to ensure high quality and good


7. Enhance capacitive load drive capability to drive capacitive loads greater than 2000pF.

8. The sound is extremely transparent, delicate and has a very good sense of music.
