I looked at the manual and did not see any comments about not using both at the same time,

USB and Coaxial at the same time?
Is there any issue with having a coaxial digital cable and a USB cable connected to my streamer at the same time? I like to compare the two by switching the input to my DDC unit. Some recordings may sound better on one rather than the other? mI read somewhere this can be a problem but if so I don't know why? Thanks.
