Just moved back to my loft after a remodel and the system is sounding good. The room is 70 feet long and 22 feet wide with a 22 ft high ceiling. It used to be a beer brewery and they converted the place to lofts. Concrete floors and ceiling.
I use the AR LS-10 solid state pre, the Ref 2 mk2 tube pre for a change of pace and then the Pass pre. All three are excellent, just different in their own ways. I can't decide, so I keep all three in a monthly rotation.
Later this year, I'm going to get an Audio Research Reference 3 preamp.
The home theater portion really cooks....I plan to get the top of the line InFocus projector later this year.

Da** look at that space and speakers and those handsome amps...( as you know I am a Pass fan).. haved you tried Pass XONO phono amps? I do like your AR front end with Pass back end , I was thinking of trying the ref2 or ref3 preamps from AR what do you think? For your space I think you have the perfect speakers, how old are those Infinities? I would give up all my system for the space you have !!!
