Currently I've got:
I've been considering upgrading for a while, but I got a nice pair of Sierra-1 speakers so I put it off for a while. I recently moved from a house in Austin, TX to an apartment out in Bellevue, WA and can no longer listen to my speakers at the levels they are meant to be heard at so now I'm strongly considering an upgrade again.
I really like the overall sound of the D7000, though I definately feel like they are lacking in the mids, and even a bit in the treble (I think this is likely due to the rolloff of the NFB-12 which I know I need to upgrade, just not sure if I'm gonna do cans or amp/dac first.) The bass is deep, but definately a bit flabby, that said, while I would like tighter bass, I don't want to give up that thick deep bass sound the D7000 deliver.
Obviously the top of my list is the LCD-2s, but I'm not sure what else would really be comparable or even worth considering.
Some of the other stuff I'm looking at is the HE-5/500/6 headphones, as well as the Beyer T1 and the Ultrasone 8s, but I don't really know how well they would compare.
Just looking for advise from people who have gotten to hear the D7000 against some of these.
Also, if you have any other headphones that I didn't list, I'm definately open to other ideas. I've not really been following any of the current releases as of late so I'm not sure what new stuff is out there.
