I'm trying to give my system a tweak with a power conditioner of some sort. I'm trying to decide between Richard Gray's Power Company 400s model or the PS Audio Ultimate Outlet High Current 15 amp model.(I have a Parasound 2205 Amp) Can anyone tell me if there is a difference between the two and if they are the same, which should I go for? This is a budget issue and I need to pick one of these low end models. Also, I will be having a dedicated outlet for my system. Thanks. R.
