I find notable differences in SQ between SPDIF cables on the 818-DSP run, and SpeakerLink run, when I had 5200s. However, I've never noticed an audible difference on the networking runs (e.g., MC200-Switch-818) only a reliability difference with good quality, shielded Cat 7 (made up as Cat 6+ due to termination).
