I can't believe I've owned my Denon for all of these years without noticing this, but I have. While redirecting some of the wiring in my HT closet yesterday I unplugged the Denon and noticed there were only 2 prongs sticking out from back of the denon to the power cord.... "CRAP"!!! I thought to myself, as I thought I'd somehow broken off the grounding prong. But after carefull inspection I realized that not only was nothing broken off inside the plug-in, there was never anything there to break off... there is no grounding prong. And yet there is a grounding prong that goes into the wall. This made me curious, are AVR's not grounded? I inspected the Emotiva and found the exact same thing, no grounding prong coming out of the back of the amp into the cord, but the other end of the cord is 3 prongs.
So do they wire the ground into either the positive or negative, or both in the wire itself? How do they ground them, if they are grounded at all. And if they aren't grounded, why not? I have seen a grounding prong coming out of the back of some appliance somewhere, I know I have, that's why I thought I'd broken it off when I didn't see it.
