Alexander and others: Check this out. Sorry about the pdf file on the Leviton page; it will take a little while to download. Look at page 4 of the Leviton site (specs on hosp. grade levitons)

Then look at:
http://www.wattgate.com/prod-381.htm
I particularly like how the Leviton and Wattgate both got an "upgraded" grounding system at the same time. Must be a coincidence. Yes, your Wattgate has gold plating on it, and I haven't heard it, so I can't really comment on its sound quality. But I can't help but think that people purchasing this receptacle are paying about $120 for that gold plating and that blue star. Maybe I'm wrong, and maybe it's worth it.....
