I used my Martin Logan at work today (I let the SR325e take a rest) and I still love them. I had not used M90 since I bought the Grados a couple of months ago.
I also have 325e. They are my favourites. I can hear the similarities between them. I got the Momentum over ear 2.0 for a very good price. But I got a hard time to stand the top that is lacking so much. They a like opposite of the Mikros. The ting is that Momentum does isolate sound better so aothers aurand don't get disturbed.
I'm really glad for the Makros 90 right now with only ten hours on them. And a got them for 64$.
