I recently went to 7.1 with rear surrounds. Originally was running 7.1 with my Denon using DSX front wides with my M2's. I am really enjoying my rear surrounds using PLIIx . I hung them from the ceiling with some AM25 pinpoint metal mounts I got off Amazon. Since the M2's are quite heavy I had to add another set screw to the mounts so they did not droop. I have the M2's tilted and angled toward the couch. I am considering in the future of adding M2's in place of my QS4's since I have found that I prefer the direct radiating surround speakers like I have set up in my bedroom 5.1. More subs are always good, so I would say go 7.2 if its in the budget . I will never go for ATMOS so this is the next best thing.
