Hello, I have little to no personal experience with good quality power conditioners in the $1,000 - $10,000 price range. Furthermore I don't understand the difference between 15 amp & 20 amp models. Is it necessary to change your in home wiring to support the use of a 20 amp model ? As for the power conditioner itself; some users claim improvements in sound quality. Others feel power conditioners can hinder the overall music quality of their systems. Let me know your experiences. Thanks, Elephant321
