Thanks for the replies!
For the TV I am going with the Sony 83" A90J. I have the 65" and love it, so I don't think I can go wrong with the larger one.
This is all being done with a basement remodel, so I have the blueprints all ready. You can take a look at the movie area at

@shadyJ, that is a good point about the Center channel. I was led to believe the Founder's series has a much warmer/neutral tone than the premier series and my only concern would be mixing the two. I'm also not sure about larger subs as I've always enjoyed the sound of smaller subs a bit more, although I'm sure tech has changed since I formed that opinion over 20 years ago. I'm also still debating sub placement, but am thinking against the couch on the long side to the left and somewhere under the bar behind the couch on the right. Or perhaps I should reverse it since most people will likely be sitting on the other side of the bar?
Appreciate all the input!
