I don't think that someone who heard your system for 30 minutes could tell the difference with new cords. Which kinda proves the point - People believe they hear things and arrive at certain conclusions.
Tuesday night I was wearing blue jeans and my system sounded very good to me. Wednesday night I was wearing slacks and it sounded just a little better. I do not conclude that slacks make my system sound better. Many people on these forums would (OK, slight exaggeration , but not by much).
