Power Conditioners to reduce Sibilance


I moved my system into a new home and was having problems with treble brightness and sibilance. I moved the speakers around and got rid of most of my troubles. I then upgraded to a more revealing preamp with money that I saved up and the problem returned (despite sonic improvements in other areas). I have read that power conditioners are great for reducing sibilance. Is this actually the case. What would you suggest for under $500US used?

I have never seen (or heard of) a power conditioner that had an effect on silibance. If it did, what else in the same range of frequencies would it affect?
Work on the speakers and the room - and get a power conditioner if you have an AC problem.
