I use a Zavfino USB but my only comparison is the stock/cheap USB that came with my DAC, but, they make great cables at very competitive prices. Construction appears similar to DH Labs.
Having said that, I was recently challenged by an AG thread about ethernet cables - I was convinced there would be no difference between my $20 blue jeans cable and something more expensive. I compared a Pangea SE premier and an AQ Cinnamon to my $20 cable.
Much to my chagrin the AQ made a significant sonic improvement over the others so I kept it (for now).
Based on this thread, I just ordered a DH Labs Reunion ethernet - if it bests the AQ I may try their USB.
