I disagree that a rooms size or shape is a reason to stick with 5.1. Have you heard of anybody going back to 5.1? Without room correction this could be an issue but after running room correction my small corner screen placed system simply came to attention with an incredibly balanced output. Room size may dictate the size of the speakers themselves, even that would be subject to personal preference.
7.1 offers better dialog placement for the L C R channels. The surround effects are now pinpoint accurate and do not rely on room reflection or the the front L and R speakers to convey the effect. The first thing I noticed is just how important the side channels are. It's simply more theater like. While the 7.1 media is slow in coming I find the effect on earlier soundtracks more enjoyable IMO.
Room correction software is a must and I'd stay away from dipole enclosures. Matching your current speakers with either used or discontinued speakers can make this one of your easiest audio upgrades.
