Rrog -- my response was to Macdadtexas, and I wasn't taking issue with your post. And for the record I think Macdadtexas is a good dude, even if we disagree on powercords.
But since you thought I was, let me note that I don't disagree with what you said particularly. My experience is different than yours in that most (but not all) of the power conditioners I have tried have had positive effects in my system, but that doesn't mean we disagree there.
But if you try to find the best speaker cable and interconnects you can find to match your system, and you agree that power cords make a difference, than why not also find the best power cords (within your budget) to match your system too?
And why assume that the power cord (unlike the speaker cable or interconnect match) is a band aid fix to something else inherently wrong. Learning about your system and your room is important for making any system chagnes. But of course one of the only ways to do this is to experiment, which can include -- among other things -- trying different power cords.
For my part, when I have tried different power cords it has not been because I was particularly unhappy about some aspect of the sound of my system, it was because I was interested in learning what a different cord (or speaker cable or interonnect) might do to change (hopefully in a positive way) the sound.
