I should have added Size and Shape...
Works for what though?...
DTS/DD recorded for 5.1 or 6.1? or DVD-Audio? or DPLII/DPLII-EX for music?
7.1 might sound great regardless of the shape and size of the room when listening to 6.1 recorded sound track.
But in reality, most of the movies and DVD-audio are recored 5.1 and the two back channels are 'matrixed'.
If you stuff in 7.1 in a small narrow room and listen to 5.1 recorded sound track, it may not add any value or even effect negatively... Well postioned 5.1 in a proper size room may work best for 5.1 recored sound tracks including movies or DVD-A/SACD
