Actually, to tell you the truth, the detail between those two headphones seemed pretty much the same. If I was to get really picky, I could hear more stuff with the D2000. But we are talking a game of inches here. The only thing I miss switching from the HD650 to the D2000 is the loss of mids. But don't worry, it's not as jaw dropping noticeable as one might think. Just don't worry at all about detail, and don't stress too much about the loss of mids. Once you hear it, you'll know what I'm talking about...
"Life" and "Energy" are two of the best words to describe the D2000. It really does put the life into your music. I've had the D2000 and the HD650 both twice, so I have a very solid impression of them both. And when switching to the HD650 to the D2000, music just starts to pop out at you. Anything along the lines you have mentioned will sound awesome with D2000, more so than the HD650. I even tested some Rammstein you mentioned, and D2000 presents it in a far more effective way than the HD650 does.
