From previous post "Also,, what kind of room are you placing this piano in? The room is very important,, because even in a small room, a concert grand would sound the same as a studio grand. I wouldn't base my decisions on size." Couldn 't agree more with the comment. We listened to several BBs and AAs at our dealer but a BB in our friends home sounded very different. Consideration of the final playing enviroment should be a signficant factor into what size you pick.. Unless I'm total off that size scales with volume...
