I live in an older, poorly grounded home in old suburb with an overloaded grid. I have most of my equipment hooked to power conditioners, except my amp. I based this decision on advice from electronic "experts" that certainly know more than I do. I don't hear any difference from when the equipment wasn't hooked to power conditioners.
That being said, my televisions do have less artifacts in low light scenes, now that they are hooked up to power conditioners. I also saw some general improvement in the overall picture quality.
