Has anyone tried using opt/coax to connect to a FiiO X5/X3 II to use as a dac/amp? Don't really want to buy a new touchscreen dap, and the xDSD checks all my requirements for a portable dac/amp (balanced out, digital in, good sq and power, can work with multiple devices)
I see no reason why it wouldn't work. It's what the port is designed for. Connecting my PC via S/PDIF to the xDSD also worked like a charm!
