Maybe check in with Morrow Audio? He sets up a booth in the Lobby. Dunno if he'd provide a loaner, but his prices are quite reasonable. And if he has used inventory with him ( I believe he does as I tried to buy a used cable off his website a few days ago and was told it was all taken to the show), it will be about 40% off.
No experience with his PC, so I can't vouch for it. But I do use his SC and IC -- they are excellent.
