I made a custom cable as I needed to feed unbalanced stereo inputs of a headphone amp(I needed 4 TRS lines with 2 outputs on tip and ring but unbalanced). Its also possible to connect balanced to unbalanced by floating the shield, connecting + to the tip and - to the case of an unbalanced connector(either RCA or quarter inch).
Exactly.

If you do cables yourself, driving -10 should be using ground and hot pins only, not connecting hot and cold together. This is the most importan point, and which is why the original DigiDesign -10 cable ever existed.

If you do cables yourself, just use ground pin and hot pin, that will not harm anything. Same goes for AES/EBU to SPDIF connection by the way.

Short-circuit may fry the card, so with this kind of thinking you can avoid that.
