Thank you very much to all of you. Indeed it sounds as I expected - altough JMLAbs 906 are very good the Twins are comparable and won't make sense to spend $500 more to move sideways. And indeed my Thule IA 60 B is very forward in revealing. I will wait for awhile to upgrade to something else (I have in head the Triangle Naia) or, maybe, I will build my own speakers and it will cost less and it will sound better.
Thank you again for your comments
