B&O would be good in there. The Beolab 5, I believe it is called, is a 4 way speaker system with a mono ICE amp for each driver, digital inputs and a built in room correction system. Also, really large spaces needn't be as concerned about room treatment. My only concern about living there, aside from Illinois weather, would be cleaning something that large. A window washer service would be very pricy. Perhaps someone on this site would know about that.
