Active Speaker Question

Has anyone experienced any improvements by plugging active speakers into a quality power conditioner rather than a quality wall outlet. Thanks.
I have active speakers plugged into a conditioner as a precaution but I heard absolutely no difference. Make sure you use a conditioner designed for power amplifiers (high current)
My Mackie's sound a little thin when plugged directly to the wall. A little more weight when plugged into my Furman, but I chose not plug the surrounds into the Furman strictly due to position and distance. The difference is too subtle to bother. I only plug the center to the Furman.
