Electrical properties of cables

I'm running a pair of 1 meter XLR VDH cables from a Benchmark DAC to a Bryston Pre. The sound in one channel is ever so slightly louder (1dB?) than the other. I especially noticed this with a 1kHz test tone while flipping the mono/stereo switch. This problem follows the cable when swapping channels. They pass a continuity check but I haven't ohm'd them out yet.

Any other suggestions before I toss them out? By the way, the custom Canare/Neutriks work just fine in this application.

A balanced XLR cable has 2 driven legs and a separate ground. If one leg -- either the Plus or the Inverted -- were not connected, you'd get signal, but the result would be down about 3 db from normal. Sounds like what you've got.

This sounds like a warranty issue, why don't you check with the manufacturer. It could be a bad solder joint on one of the legs.

I considered a cold solder joint when I checked for continuity from pin to pin on each leg. Everything checks OK. But your right, contact must have been compromised somewhere at the connectors. I'll have to e-mail Van den Hul.

Thanks!
