See T90. What DT990(pro) wishes to be, I believe, although the 600-ohm version of DT990 Premium already fixes everything I dislike about DT990pro's sound while remaining oh so very fun, and then T90 goes even farther. I love my T90, but if it weren't around, I would gladly have a DT990-600ohm instead. This one may turn out to be "DT1880" in the sense that you're thinking, for all we know.
