Depends on what you're looking for. 3000ANV has a unique coloration that can be a very seductive sound signature. Liquid-y is probably the way to describe the overall package. That being said, the 3000ANV presentation was a bit too outlandish and too heavily colored (IMO); the TH-900 toes the line in being overly bassy, but is in the just right-ish range of porridge for me when it comes to enjoying music. The TH-900 is the headphone for me when I want to groove to songs.
th-900 is awesome, its a bass monster and just as fun as D7000.
