Can you go to a meet and try the LCD2s there?
I got rid of my HD650s as they did not have enough "bass satisfaction". I am also a bit concerned that there might be better, cheaper coices (say the Denon or Ultrasones) than LCD2s for bassy music.
I put some cotton wool around the inside of the ear pads and the comfort is better.
I must say, the ear pads are pretty bad. All wonky, its not a perfect circle, or any logical shape that I can determine.
