How are Soliloquy's in HT?

I've read many reviews on these speakers and many owners seem to be happy? On the HT side, how do they perform? The reason I ask is last week, I listened to the 6.5 and 5.3. On the music side, I had no complaints but something was missing when viewing a movie in HT? One thing I should mention, on the music side they were hooked to a marsh amp(A400), in HT they were hooked up to the Cary Cinema 5. Detail and dynamics just weren't there. It was hooked up to a AAD sub. Could it be the Sol center channel isn't up to par? Could it be the Sol's are good on the music side but not in HT?

I was hoping to listen to the 6.3 but they didn't not have any to listen to.

thanks
