Headphoneus Supremus
I have the Audioengine D1 and the creative E5. Both should be able to drive them, but I don't know if they're a good match though.
I know that the AKG 700 are hard to amp and that's why I didn't consider them for my choice.
I'm a bit conflicted about the DT880. I read that they sound dry/harsh and the treble is peaky. As I said before, I don't mind treble as long as it's not too much.
The DT880 have a nice balanced sound, the sound is slightly on the bright side.
I own the two DT880 (250-Ohm and 600-Ohm) headphones.
But I'm currently using the HP200 (listening to Maxi Trusso Nothing at all) and feel that I have no need or want to switch over to the DT880.
