To Albertporter: Do the hospital grade wall outlets with the silver colored anti corrosion plating inside sound worse, the same, or better than an average wall outlet that is normally in a wall? I've just had hospital grade outlets installed and don't know what brand they are or what plating is inside. It was what the electrician had on hand.I'm interested in knowing. I've just sold my speakers and am waiting on new ones, so I can't listen for myself right now. Thank you very much.
