the utopias would be a logical step. much better than the mezzo. i went from utopias to novas, to martin logan ascents, odysseys, and now prodigys. i have owned the sound lab u1s a3s etc. i can tell you for around 6 to 7k used the prodigys set up properly, will compete with any speaker regaurdless of cost. i would in that size room go for the statememt e2s . they are as the other person mentioned around 30k. good luck. what kind of amps are you useing? at that kind of money you have no limits to what kind of great sound you will have.
