Hi all, I've been wondering about the feasibility of changing my DT990 600 ohms drivers for a pair of T1 drivers. They both seem to have the same cup size and the same locking ring. The only differences are that the the DT990 is fully open while the T1 is semi-open and the DT990 has damping on the back of the cup (easily removable) while the T1 doesn't have any damping. Some people mod their T1 to add damping so keeping the DT990's stock damping could be a good idea.
I am really tempted to try it out and order a pair of replacement T1 drivers from Beyerdynamics. What do you think about this?
