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.
As in 320, 192kbps? Yah, I even tried on podcasts. Next time it happens I might pop a CD in and see what happens. Hmmm I wonder if its DAC related. I just got a new DAC (Fostex HPA8C). Ill try switching that off and on instead of the laptop next time.
