Thanks, Grey, I'd actually need to use the coax connector as all 4 of my S/PDIF are currently in use. Since I'm Pi ignorant, wonder if any of you have any thoughts on the Google Chromecast Audio product? 96/24 output from the combo 3.5mm stereo/optical S/PDIF connector. Not sure of full DLNA compliance with my JRiver, Subsonic or WMP servers, but I suspect it's there. Comments? Thanks, guys.
