I have made my own shielded power cords for decades using three conductor 12 gauge cable with a foil shield. I hook the shield up on the house side only. Does it help? I have an extremely quiet system but I can not tell how much the cords add to it. There is certainly no down side as long as you do not hook up both sides of the shield which might produce ground loop hum. There are lots of very sturdy plugs out there. I use Marinco plugs.
