I thought the DT880 had a very nice bass, with good power and impact, and this is coming from a guy who mainly listens to heavy metal. In fact I liked the sound all around, it seemed very balanced, detailed, and accurate. My only complaint would be that it is like the anti-DT531 in that it just doesn't get you into the music, I spent more time analyzing each part of the sound, no matter the system I stuck it in. If I had infinite funds, I would buy a DT880, simply because of their accuracy, they look to be a great tool for testing out other gear, and seeing how it changes. I also liked the typically great Beyer build quality and comfort. I get a more musically fufilling experience, whether listening to metal/rock, classical, or techno, from the CD3K woody, but I can definitely see the proper place in one's lineup for a DT880. It did do quite well with my Gilmore V1, I actually liked the sound of that better than the Grace 901 with these cans, though a great tube amp really brings out the mids (of course that goes for any cans) for the best overall sound I've heard from them.
