Well, in the land of Toxic dumps (New Jersey) one always has voltage fluctuation. The line conditioner I have used for years (a panamax) died on me. However I never thought that I had dirty power until my dvd players started showing image flutter on my new projector setup. It is then that I started to run the tests.....the conclusion was that the line conditioner helped the flutter in the image dissapear.
