Sorry vut my final question is do any of these headphones mentioned make good music producing cans. I forgot to point out that I don't care about open or sealed and these headphones will be mostly for home use.
Thank you for the help
I have the 7100 and the T1 and find the T1 to be a very good hi-end all-rounder with the right amp. I just got an Onkyo integrated amp in for some insight into the Onkyo house sound and was blown away when I plugged the T1 in it. The bass quantity and quality was insanely good, almost as much rumble as my D7000. My Asgard couldn't do this to the T1, not even close. The Onkyo amp also controls the T1's treble quite nicely, not nearly as much sibilance as with the Asgard. The 7100, while very good with mainstream music, is not so brilliant with classical and instrumentals - the sound stage, albeit wide, is too 2D-ish and lags behind the T1 by a bit.
I'd have kept the amp if this sucker didn't weight 23 Ibs though (it drives speakers after all), planning to return it and get something else less heavy.
