My Auralic G2.1 streamer requires setup changes to swap from USB to Coax making it about a minute long process to switch and not so easy to A/B.
unless you have the same cable it also makes it really hard to compare which is better. But you can see which in your setup you prefer with what you have.
that all being said, I do have both cables plugged in simultaneously and I hope that there is no downside to that.
