Now experience with what real instruments sound like in person is limited for most people.
In my experience the D2000 reflect reality more accurately more often than the HD650, which tends to be more accurate to the digital mixed version of the music. Which is why it's a more clinical boring pair of cans. It does not reflect as well the raw reality, but a restrained interpretation of the person in charge of mixing.
When I listen to my music (from classical, soundtrack, to jazz, rock, pop) I want to feel like I'm there amongst the instruments, not in a booth. Others like to hear what the person in charge of mastering and mixing decided to convey.
