Separate power supply for DIGI and DAC


I'd like to equip raspberry pi and DIGI or DAC each with separate power units.
How is the pin configuration for this aim.
I'm planning a complete separation of power supplies between raspberry pi and DIGI or DAC. I've purchased both hifiberry components and they work without technical problems, but I believe there's more sound potential through optimizing power conditions.

Greetings, Robert
