Brb9, you're right. That's why I vote for 803D. I heard them and heard the N802 and to me the 803D is just more refined. That diamond tweeter is silky smooth. The bass is tighter and more resolving than the N802's. And the mids are smoother and more full sounding.
I own N803 and although I got them to sound pretty good, the 803D is in another league. So much so, that it outperforms even the N802 by a nice margin. Just my personal observation.
