I have a related question.  Why don't audio components (and video
too for that matter) use grounded plugs?  It seems like such a
simple thing to do yet I've never seen any audio equipment that
used them.  My reciever-amp has a ground connection for the antenna
(which is hooked up) but I'm not sure this is the same.  Even if
it is, it couldn't do anything for the rest of the components.
