I am certain it's the size of the rooms in my case. There is just so much you can do with a huge open space like my main system is in. My office is very small so it's easy to fill with sound.
Same here, I know I haven't posted pics of my main system, but the downstairs is completely open, the living room, kitchen, dining room, stairwell, it's all wide open, but my bedroom is just one room and it sounds so good in there.
