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.

I'll second Andirocks......
Most amps have a switch you need to use for either RCAs or XLRs......

From the Reference 110 Owners Manual it is a fully balanced topography with no switches for XLR vs Single Ended Input, confirmed via the pic of rear view.

Manual Reads as Follows:
Connections:
INPUT CONNECTOR: The Reference 110 uses a fully balanced circuit topology and has a pair of balanced XLR input connectors on the rear panel. It therefore requires a balanced preamplifier output, as provided by most Audio Research preamplifiers. Connect your preamplifier's output to the Reference 110 before turning on the amplifier.

Very odd indeed!

There is a slim chance it has to do with tolerances of the plugs and ports. I have encountered situations where a power cord didn't work with one product but did with all others. Similarly, I had an RCA interconnect once which would not fit onto a preamp, though it did with most. A very slight mismatch could spell a missed connection and silence.
