500+ Head-Fier
Another thing I forgot to add to my little spiel, is soundstage. I had the pleasure of trying the HD800S at a store, and found out how immense the soundstage is, at least compared to everything else I have heard. I had to take them off to make sure the music wasn't playing through the speakers in front of me. When it comes to soundstage, I want to take a guess and say angled drivers and distance from your ears play the biggest part in the illusion. I tried equalizing the HD650 to HD800 response, but didn't get nearly that immense of a perceived soundstage. So, maybe the angled drivers sound reflects off the pinna shape of the ears and trick the brain into thinking it's further away than it actually is? I'm sure the larger driver diaphragm helps too.
