Never knew we had a community of Audio Technica fans here!

I own an ES7 myself, proudly too. My first 'expensive' pair of cans and still the only expensive one I'm using.

I'm satisfied with the sound of it all, mainly because I'm not a very demanding user, but since I have a bigger head than most it makes me look stupid when I wear it, that and the fatigue kicks in roughly bout 40mins-1hour later.

AD900 did catch my eyes, I don't mind the price... but comfort and sound quality wise, I'm hoping you gurus can provide insights if compared to the ES7.
