Just cannot seem to get my dialog blended correctly

Home theater set up is Marantz SR7600 powering my center CS250
SDA 2Bs are running off of my Yamaha AV 34 via pre outs from the receiver but I just cannot seem to get the dialog to blend well. Always seems too low so I have to crank it up, then with the dynamics hit the whole place is shaking (not good for apartment living). I have tried bumping up the center all the way to +10db, tried a different speaker, replaced cables etc.

I can set it to dolby pro logic and it seems well but I feel like I lose a lot of dynamics from the SDAs when the action hits.
