I have a Servo-15 that picks up my neighbors CB, whether it is connected to my system or not. My dealer recommended teh PSAudio Ultimate Outlet as a solution to this (assuming a cheater plug test works). It's a spendy little unit and wanted to see if anyone here has had any experience with it. I do get a fair amount of power interference on my system since it's on a common circuit in the house so I thought this might help me there as well. I've always hated getting interference in my speakers when the bathroom fan gets turned on.
