I have the same DAC I use blue jeans cables ethernet to do all the streaming. I have a modded Mac mini as my ROON core. Ethernet our of the Mac into the ethernet switch and ethernet into the 780d. I have a low noise power supply to the switch. I mod the moon with synergistic blue fuses and audioquest z power cord. I use pure silver IC from this guy joe at tempo electric.
