Hi Wesley - terrific to see you here, and welcome. :) You've mentioned elsewhere that the SB3 is a great transport to use with your D100 DAC. I recently learned the following about the SB3 (from JohnSwenson-thanks John!), regarding the SB3's S/PDIF output:

Also please, are these potential concerns perhaps avoided, by just using optical output from an SB3 instead of the coax output?
