Op, it looks like the others have hi-jacked your post, but my suggestion to you is to try both DAC chipsets and use the the output that sounds the best to you.
1) XLR output will use the OPPO - ESS Sabre DAC
2) USB or S/PDIF/Optical (digital connection) output will use the Hegel - AKM DAC
Good luck!
