You know, it’s not IMHO the PC or the motherboard, but the PC’s power supply noise. Try to keep the PC’s power supply outside of your surge protection / AC noise filtering devices. Or at least put the on separate. Also if possible, experiment via the PC’s optical out as well. Kind of tricky part: Keep PC and audio on same AC circuit if using electrical based contacts.
In theory, USB is best due to the DAC’s ability to pull based on it’s internal clock, but sometimes the galvanic (electrical) isolation of the optical cable is superior.
I use a Raspberry Pi based streamer which uses a little bitty wall wart, and I keep that on a different surge protection. I should consider getting a linear supply for it instead.
