CT221933 - Have you received any useful responses amidst these 'cable wars'? (I assume it's not helpful just to hear that some posters don't believe A/C cords make a difference, and read the ensuing rebuttals.)
There is no reason you cannot mix-and-match A/C cords in your system. If you have different ones, try them on various components and listen.
OTOH, once you find a cord that you especially like, you may find that it sounds better than others throughout your system.
