Toward the end of this thread: your topic question is discussed.
I know that Audiolabyrinth (Audiogon user name) has done a lot of experimentation on the topic but I can't find the article.
You could always PM him.
I'm not worried about the screws in your wall plate. I'm more worried about the screws in your head.
Labyrinth has posted impressively about that. Maybe in his tara labs thread.
