For me, even though I have reasonably good quality equipment capable of a full 7.2.4 with channels to spare for Bi-Amping or separate stereo music speakers, I find it's just not feasible to have a setup in my house without making it look like an electronics showroom. I think for a large segment of people, that unless you have a dedicated home theater room that's suitable for a proper Atmos/DTS-X setup, most of us don't have that extra space in our homes, and the rooms we do have can barely accommodate 5.1 systems. I personally can't put anything in the ceiling due to blown in insulation making it too much hassle to run wires up there. So I've gone with just a 5.2 plus using front wides since I can't get anything behind the seating area without disrupting the decor of the attached room they would be in. Could possibly add front heights on front wall, but again hard to hide the wires. And would it really add that much difference most of the time. I think not. So I would say buy the best equipment you can afford that best matches the setup your really going to have, and don't dilute your quality so you can buy bells & whistles your probably never going to use. So for me, my 7.2 is still pretty good sounding without the height effects, and I don't really think I'm missing much.
