ProtoDAC TDA1387 X8 project

Allo Isolator only works with master DACs. ProtoDAC is a slave DAC.

I am sure an isolator will improve sound quality.

I cannot recommend any of the Ian Canada isolator/reclockers, because they use a nonstandard GPIO (3.3V on pins 2 and 4 instead of 5V).

I have found that a single CPU core has lower noise. You can try adding "maxcpus=1" to the end of the line in /boot/firmware/cmdline.txt if your RPi is multicore. Use the command lscpu to verify. It's free and easily reversible.
