Audience XLR interconnects not working

..just purchased (used) XLR Audience AU 24e interconnects. I have tried them in my rig which is essentially Audio Research (CD5, Ref 5, Ref 110 plus Sony as an additional SACD source). I have tried the Audience source to pre, pre to power but not a whimper. Completely dead. Yet they work with a friend's rig which is Oppo and solid state amplification. Any ideas why? Is the wiring of the "hot" pin not compatible with AR? As a non-shielded interconnect is there something clashing there? There is no buzz, no mush...just silence. I am bewildered.

XLR was originally for studio Mics. They sometimes have Phantom Power on them (used to power the pre-amp in the Mic body and so need for batteries)

This can cause "Ghosting" and the ghost signals can be 180 degrees out of phase with the phantom signal, so the ghost and phantom cancel each other out.

It's a major problem so called "electrical engineers" can't explain.

I don't quite know how to cure it, but surely your friends rig is not haunted with the same problems? Ask him if he had to excorcise the problem, and how?
