I think I have the exact same opinion! I tried the HD800's, and while I appreciated the detail and certainly the comfort, I just didn't love them. I tried the HD700's too, and while an improvement (for me) from the HD800's, I still just didn't stop focusing on the headphones and listen to the music. I finally got to listen to some LCD-2's and completely drifted into the music, ignoring the headphones themselves.
So, I'll be really curious to read what you think. I had several Sennheiser headphones prior to the LCD-2's, and loved them all.
