I pretty much did the same thing with mine. I went all out. I did the markl mod, d7k cups, jmoney earpads, and a recable. The end result was something that didn't sound anything like a d2k. The mids were much warmer, bass was tight, and sibilance was greatly reduced. But on the other hand, I lost a lot of the things I did like about the d2k's. I also wondered how close they would sound to the real d7k's. Well now since I own a pair, judging from memory, it's not even close. The modded d2k's did sound better than stock, but still no d7k. But it was a very fun project. Drake22 you did a very nice job on those. What cable did you use?
