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.

Have you tried any other balanced interconnects in the same position ?

Best of luck

I'll second both of the previous comments. Also, consider purchasing or obtaining a multimeter, and checking the cables for continuity from each pin at one end to the corresponding pin at the other end. And also checking that there is no continuity from each pin to either of the other two pins.

Also, your mention of the cables being non-shielded leads me to wonder if continuity is present between pin 1 (ground) at one end and pin 1 at the other end. I doubt that any reputable company would market a cable designed like that, and I suspect that if pin 1 were unconnected you would still hear something, but I suppose an open ground connection could account for differing behavior in your system vs. your friend's, depending on the design of the various components.
