Good review Frank I. Thanks. I've been so impressed with Beyer over the past year. Had a few days on their flagship T1 in April and yes, a special piece to own. Believe the hype. As well as their DT-990 (600 ohm)...not quite T1's equal but it's worthy in it's own right. Got the DT-880's (250 ohm) breaking in now with many sonic characteristics as the 990. I'm not saying I've road tested all phones available but all the Beyers I've had the pleasure of sampling (and owning) will keep me with them for quite a while.
