Dear Sirs,

May I have your help to review the design/layout and give me some comments?

Customer hopes to know if there is anything they can do to improve their product audio performance.

Thanks.

    Hello Peter,

    I reviewed the files ( I think I have seen the schematics before). I just noticed in many places a 10uF/16V along with another  10uF/50V caps were used for decupling. I usually put  a  10uF ,low frequency noise decoupling,  along with a 0.1uF for high frequency noise decoupling. Layout is good as well - specially that GND layer is right under signal layer 1 (I myself prefer this way) .

    Regards,

    Arash
