On the power lines adding more dedicated outlets so you do not have all you digital bunched up on one line. Digital can send noise backwards through the power cord to the dedicated digital outlet ie if you have multiple CD sources {CD recorders , DVD players , Dedicated redbook, throw in an AV pre amp , how about your HDTV, your digital cable tv box ,they are all on the same line and its a noise party.I dont care what PLC or PC you have , get multiple dedicated digital electrical lines , the difference can be amazing.
