I'm using Synergistic Research Resolution Reference FX speaker cables as recommended by Ted Denney III, their lead designer, on my Contour 5.4's. He assured me they would make an unbelievable difference, and it was no idle boast, my system now sounds like I always thought it should, instead of how I wished it would. I borrowed cables from The Cable Company's lending library, and bought new immediately. They even let me keep the loaners 'til new ones came in. Highly recommended. Best, Dan
