I received my D7000s last Friday and I've been listening to them quite a bit while I burn them in. For most of my music collection, I like the D7000 better than the HD800. When I listen to the D7000, I get deeply involved with my music. When I listen to the HD800, I think about all the audiophile stuff like how big the soundstage is and the separation of images but I don't get into the music nearly as much.
Yeah...I agree. The great thing is, if you have both in your collection, and possibly a T1
you're really set for all sorts of music listening, whether critical or just for fun and rocking out.
