Umm dedicated line helped me some with systen details and dynamics but since there are other ways to try things before you buy I would say try a Hydra or Exact Power AC conditioner, you can get these form soem Agon dealer to try out first. Next Granite Audio has a Ground Zero unit that I am going to try soon myself, also trail period. If these do not get you the desired results then try a dedicated line. Outlets are also recommended for the $40 each price tag but they will not quite your system.
Happy Listening.
