Hospital Grade Wall Outlets

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.

To Albert Porter or Jctubes or anybody: I appreciate your input, but does a cheaper hospital grade plug with nickel plating or etc. sound worse, the same, or maybe a little better than an average everyday wall outlet? I know that I would have better results with a higher grade hospital outlet, but I am just wondering if I am worse off than before when I had an electrician change the average household outlets to the hospital grade outlets that he had on hand (probably a lower grade brand). Thanks, Edward

Thank you Albertporter. Edward
