I was talking to a guy in Canada on Friday and had him to $310 including a fancy cable, but junk pads, and they were made in '13, but someone came in over me. Might as well sell my MD TH-X00 and buy another pair of 500's, I can level match the drivers to create a really good set. Funny 3 months ago they were running mid 300's/low 400's. If they are sound, have one of the good pads, and you take out the screen there is nothing new that can touch them under $700 - as long as you have an amp to drive them. They don't do much on portables.
