    hello everyone
    i am building the below amp based on this thread , but i will put two daughter boards, one for the protection board and the other for the amp ucd drive.

    i will change the protection to manoj aud600 protection cause it was the only effecient and effective i have ever came across so far.

    The other daughter board for ucd protection will be able to change from discreet to ic version or even sigma delta mode , by just changing the board.

    opinions and ideas are highly welcomed and appreciated

    photos are below , i have failed to upload here
