My simple experience of a major improvement is similar to that of Lowrider57, with a Mapleshade Records Power Strip/Conditioner plugged into an AC wall outlet (this is not current limiting) together with a Machina Dynamica "Flying Saucer (RFI/EMI blocker) for AC outlet" plugged into the adjacent remaining AC outlet, as well as into a number of other unused AC outlets throughout listening room.
Easy to hear wonderful system wide improvement.
Modest cost with big benefit.
