Just sold my u12t after comparing it to the Phoenix.
I loved the u12t for the authentic sound signature, but the Phoenix is the best of all worlds, incl perfect dynamics.
I also have the EXT here and to my personal preference, the bass is a little bit too much (using the 3max). I also used a SP2k yesterday and the bass with the EXT was much more defined. But I missed the great dynamics of the 3max..
