Troublemaker.Well, insanely bad design from a super popular brands unfortunately exist. See my measurements of a few USB cables and impact on actual output of a DAC:
Now this doesn't mean an audiophile cable is better (see my tests). It is just that this is not a matter of impossibility. There is a USB bus whaling inside the DAC and must be isolated very well from the rest of DAC.
