My yamaha 765 has a built in mains cable so i presume i cannot upgrade the mains cable? So do i plug it in the mains conditioner or into a seperate solo socket. Also is it recomended all components [LCD,BLU-RAY,SKY-HD,PS3,AMPLIFIER] have an mains cable upgrade or do i just run them though my mains conditioner. IM SURE USE HAVE BEEN ASKED A ZILLION TIMES,
