When I test DAC's without galvanic isolation on the USB interface, I can clearly hear differences between different connected computers, and supplies. With Galvanic isolation, it helps reduce the differences, but doesn't sound as good as the galvanic isolation adds jitter. It wasn't until I tested the Phison PD2 with both galvanic isolation, and reclocking via flip flop that I heard no differences between connected computers.
