Speaking of which, how hard would it be to do as suggested way back when and replace the mic line for S/PDIF Coax output? Wiring from the Eutronix sound card to the harness within the player I mean, not replacing the pins/wiring on the back of the sled.

Would we even want to try to mount toslink in the sled for repeated removal/insertion? There are transceivers to change a coax signal to optical if you are worried about interference. I think this would be a better approach for those that use the Eutronix for digital output.

But this is just my $.02
