Actually on mine I run High end cables on the front two channels , mid end on the surrounds, and low end on the center and sub. Only because this is what I had available.
Recently for the first time I listened to the DVD player do normal Dolby Digital Surround, usually I use the processor, and noticed the processor sounded "better" . I concluded that it was the inferior cables of the surrounds etc. on the multi channel input. whether you want to spend $4-500.00 3 times on three sets of interconnects is a personal choice. For me , Im just concerned the 2 channel is precise.
