Me too I want to buy the oppo Ha-2 and use my A17 using the Fiio L5 while i search for a digital IN sony cable
There is the Sony cable, but if you want to bypass both the DAC and amp in the A17 and use the Oppo (and why wouldn't you?) you need to also have a USB to micro USB adapter that takes the Sony cable out (full size USB) and then connects to the micro USB input on the Oppo. I am seriously considering seeing if somebody can't take a Sony cable and re-terminate it with a micro USB.
