Jab,
I'm not sure that's globally true. I have two dedicated lines and different power cords make significant changes in my system. I heard less difference at the time when I moved from a non-dedicated line to a dedicated one (that is, with no power cord changes). I will say my system then was less evolved than it is today. I'm not saying there aren't very good reasons to move to a dedicated line...because I completely agree that there are.
Another area for improvement is a good A/C outlet.
