My combo RPi3 with Digi+ connected to Tubedac-11 by coax sounds much better than macbook pro with Aurvana player connected to the same DAC via USB. To use PC like a quality music source you will need to build your own mITX solution with SOTM pci-e to usb board that quite expensive

RPi3 with Digi+ and Linear PSU is the real deal.
