I think the HagUSB performs very well, I have been using one for years. A few AC members have been over and liked what they heard. The output of the HagUSB is S/PDIF but maybe it can be modified, only Jim would know.
Do the wiring below in reverse? I dunno.
From Sound on Sound:
"However, although it is a rather makeshift solution (a 'bodge', to use the technical term), if you only need the signal to travel a fairly short distance — say, no more than two metres — you can get an AES output to feed an S/PDIF input with just a simple XLR-to-phono cable. Wire pin 2 of the XLR to the tip of the RCA phono jack, and pin 3 of the XLR to the sleeve of the phono. Pin 1 of the XLR should remain wired to the cable screen at the XLR end, but leave it disconnected and insulated at the phono end.
Strictly speaking, the Channel Status and other subcode data is formatted differently between AES and S/PDIF, but very little equipment bothers to send or read the full subcode data set anyway, so it is rarely a problem."
