try a power line conditioner. i have a richard gray ps400 and plugged it into a run of the mill sony....great results. even my wife (who thinks i am insane with the audio gear said the tv looks better!) i do not have a detachable cord. the few guys in my audio club who have changed cords on their sets have improved results....but not necessarly with the audio cords that sounded the best in their system.
Ever add a Aftermarket Cord to a TV?
I would think that of all the components that could benefit from an aftermarket cord, it would be a TV. Anyone ever try this? Would like to know b4 I snip my 32XBR.
