Those who are skeptic(cough-Don-cough) ask Bob_Bundus, he will tell you his experiences(who stick's out in my mind as being the biggest protagonist for PC's, he loves those little devils!) It is one of those unexplainable(to me at least) phenomena in audio, as suggested above give it a shot, the cables will speak for them selves. BTW thanks Don for telling me not to give up :) last night I took everything apart-cleaned the life out of it and relocated somethings and the rig has never sounded better.
