My experience with the D2000 was very disappointing. Lumpy bass and mid-bass, very recessed mids, and too forward, grainy treble. Very much a "V" response headphone. If you like that sort of sound, they may appeal to you. I just bought the Kenwood from another HFer, they are supposed to arrive later today and I'll report on them. The JVCs, Edition 8/9 and Signature Pro have a pretty good reputation. I'm not that familiar with the Audio-Technica woodies but from what I've read most have pretty heavy levels of coloration in the midrange, and range from bass light to bass non-existent. You tend not to hear much about the aluminum versions like the A1000X, though Headfonia did review them. I haven't heard the Lawton mods so I can't comment on how much better they are to the stock Denons.
I'm surprised nobody has yet mentioned the Headphile Terminator or Smeggy Thunderpants.
By the way, Bluetin Japan sells the Kenwood for $360 US.
