You know, neither of those speakers are really dynamic with HT period! the Aerials are even lower sensitivity/more anemic dynamically! Of all the speakers you just mentioned, unless you have a small room, I'd sell the the others, and do 3 CC3's if you must! (set-up standing up!) You'd get much much better dynamics with those Diappolito speakers!..really! Anyway, its a thought.
However, if you absoutely must, you should get a cc3 for the CDM2's if you plan on keeping em..but for dedicated HT, why would you?...they're music speakers!..not HT speakers
Good Luck
