7. The op amp provides a total of 18V power supply of 9V.
* Zishan balances the advantages and disadvantages of power consumption and performance, using a 9V power supply, with 19pcs MLCCs, a total of 1900uF filters, to meet the sudden change of current in large dynamic music.

8. Dual ES9038Q2M DAC chip and TI OPA1622 headphone amplifier
* Z4 contains two ES9038Q2M chips. Various filtering functions of ES9038Q2M are opened.
