I vote lcd2, I can give more opinions with my new amplifier on Wednesday, I recommend buying open box LCD2 from "razor dog audio" for 795$ it has fully warranty etc
I went from he500 to LCD2 because the comfort levels were a big difference for me, and the lcd2 fits and feels like an expensive headphone, you definitely feel glad to own them. They're easier to take care of as well.
Sound was also a difference, they image better and have way better bass and mids. Treble is just as good as well
