And I guess to contribute more to this thread I shall add in my impressions as well. I used to own the D2000 and recabled it with some Kimber 4TC (never again, eventhough there is an improvement but the cable is too stiff for HP use) and performed a variant of the markl mod.
I especially liked the bass response, versatility and comfort. However, the mids were a little bit too recessed for my liking and no matter what I did, I could never truly get rid of the annoying sibilance issue that seemed to occur around the 10kHz spectrum. In the end I sold it to fund for the HF2 which I hope will be worth it.
