I had the 32ohm which the ONE person who compared every single DT770/880/990 of the recent years say sound closest to the 600ohm version. Better than even the 250ohm. I found my 32ohm very balanced, and wasn't particularly lacking anything. However like Rage said, the rear positioning in particular was lacking quite a bit vs almost every single headphone that I liked for gaming.
Sad to hear, though I have a feeling the DT770/600 (being closed) will sound pretty fantastic for gaming. If they have the positioning and large soundstage that the DT770 Pro 80's had for a closed headphone, but with the balanced sound I hear they have, they may as well be the best gaming headphones for the price, IMHO. I simply MUST hear them. I'd like to hear the DT990/600 as well. If they're bassy but not boomy, they may be the one of the best single player cans too. I dunno, I'd like to gamble on the DT990/600 as my ONE gaming headphone for all purposes, but I'd have to wait for the E9 for amping and sell my K701 and maybe even the CAL....which I rather not risk doing...
I no longer NEED a closed headphone (my computer is outside the bedroom).
From this thread:http://www.head-fi.org/forum/thread/...en-dt770-dt990
...it seems the DT990/600 has the largest soundstage out of all the Beyer DTs, and has either identical or better imaging than the DT880/600 too. That sounds like a winner to me. I'd really like to try it. I liked the DT880/32's soundstage, so even more than that sounds great. I may just end up getting the DT990/600 + E9 for this holidays, and keeping my K701 for the highly competitive stuff. Dunno about the CAL...but I will miss them if I give them up.
