My only experience with Chord products is the QuteHD, and don't recall having these issues on my NF9C board. It's a slow CPU. So this problem you're having seems to be related to the 2Qute, and it seems computer related and not electrical. That is good.
Since there are people with this issue, have you tried checking with Chord and hear what they say?
Lots of interrupts on the USB is normal, that is the downside of a USB audio device. If you run the computer for a while and look at the running processes, the USB process will consume the most CPU time. All this is normal, and nothing much we can do about it, it's a limitation of USB. You can increase the MTU to improve the network latency, but if this is a known Chord issue, probably best to leave it to Chord to find a fix and issue an update to their DAC firmware (assuming this DAC is upgradable).
