Wow I just read through this whole thread and I am very impressed!
A few questions:
-Are those klipsch towers in the theater? If so do they voice match with the goldenears? Or is this temporary until you can get the Goldenear 5 that you mentioned earlier? If you are leaning toward the Goldenear 5 I suggest you go with the 7s and save some money especially since you are running an external sub.

-How will the granite counter top accommodate the pilars?

-I see you have a pretty extensive server system for media which is awesome for movies, did you consider Sonos Connects for music? With the separate music zones I find nothing is easier than Sonos and guests can easily use the system (emphasis on easily) with just the app on their phone. I have 5 Sonos Connects in my house, each hooked up to its own stereo/HT setup and it couldn't be easier to use and the sound quality is excellent (especially when run through a nice DAC).

I don't think it is a huge deal but considering all you spent on sound proofing the room I would have matching speakers. I owned a pair of Goldenears and I thought they were over-hyped. If you like the klipsches just swap out the goldenears with klipsch replacements.
