When I was auditioning headphones six weeks or so ago, I listened long and hard at the DT880 premium. I assume you have the premium...I think I read that the pro's only came in 250ohm model. I ended up buying the DT990 premiums for the thump, but it turns out they sold me the 32ohm version and it didn't match up right with the amp I bought, so they went back and since they didn't have the 600 ohm model, I opted for the sonic neutrality of the Sennheiser HD600. Then a week or two later I got a pair of used DT990 pro off of ebay. Those sound great too, but they don't have the shizzle of the 990 premium (which REALLY have an exciting low end thump if you're into that). I like electronic music so that's something I want more of even than the 990 pro which has a reasonable thump on it own, so I'm thinking about upgrading to the 990 premium. That said, I do enjoy having the sonically neutral phones for both listening enjoyment but especially for mastering and that would probably be the desert island pair if I had to select only one pair of high quality phones to use.
My ATH-M50 are what I haul out to the show now. I've kinda stopped listening to them at home because the open back phones just have a more airy natural sound that is great for mastering.
