Power Cables


Is it necessary to use the same brand and model of power cables for the amp and pre-amp? Any thoughts about mixing and matching? I know it all comes down to how they sound, but would love to hear your inputs or tips to guide me in the selection.

How about we all relax and drop this useless back and forth griping? That is my plan :-

My personal quest is to find power cords that look inconspicuous hanging from the power outlets and running along the floor moldings. ;-)
