I use a battery operated tablet to mitigate the issues highlighted by Stephen. No SMPS noise source. It is connected to my Yggy via a 1.5M Platinum somethingorother from WW.
Dedicated end point devices may produce less noise on the USB lines. But I would have to measure it to be convinced because I’ve seen some terrible digital designs from high end audio companies.
I’d also note that not all DAC USB inputs have the same level of isolation. There are multiple stages of USB transformer isolation on the Schiit Unison board. Looking at the parts on the board I count three separate stages of isolation. So not all DACs are equal. Some are more equal than others.
