If your Yiggy is fully broken-in, you should hear a noticeable difference in SQ compared to the Node dac.
I suggest you audition a different S/PDIF coax. Each digital cable I have used has presented a discernable difference in sonics. Your Audioquest digital cable may be a weak link. Maybe try a brand other than Audioquest.
