Where can I find a Denon link cable at a reasonable cost? Or could a simply use an ethernet cable. If that is the case, will the ethernet cable be straight through or crossover?
My original Denon Link cable looks like it is a CAT5E or 6 STP (shielded) straight patch cable. I think that AudioQuest has a Cat5E that some people reported it worked with the DLIII. Mine came with the DVD-2930.
