You also chose the Marantz AV7706 processor, which is an excellent choice as it has really nice power supply and discrete audio stage. However, it is voiced very slightly on the soft/warm side because it softens and rolls off the high frequencies.
For this reason, I would probably avoid the Parasound and Marantz amps. The Parasound are extremely clean in the midrange, but they have a dry type of sound and they do not have the highest resolution in high frequencies. The Marantz typical voice is on the warm side, so I would be cautious about that amp as well. You may end up with a HT system that is not exciting enough.
I would lean towards the Audio Control amp because I'm assuming it is going to be a faster responding and more transparent / exciting amplifier. Another amp you can look into are the ATI AT4000 or AT6000 series amps (ranging from 2 channel to 7 channel models). They are excellent quality and have a lot of current capability and fast response.
The Audio Control Savoy G4 is likely a very good amp, but it is very light at only 43 lbs. For a 5 channel amp, this means the transformer and power supplies are not that large and are not going to push as much current. The smaller size ATI AT4000 range from 77 lbs (2-channel model) up to 119 lbs. The larger AT6000 range from 107 lbs to 165 lbs. This weight tells you that it contains very large transformers and power supplies that can give you enormous amounts of current. The ATI amps are also fully differential/balanced amps. The Savoy is sort of balance for 2 of the channels since you can "bridge" them for double power.
