That sounds like an expensive way to go... do you mean for your in-wall speaker wire? I'm just gonna throw it out there because it might save you a good deal of money. If you bought boutique speaker cable to run in the wall, and don't have a seriously high end system (with the wallet to match), there's a good chance you're overspending. Any half decent speaker cable should do fine, and if in-wall, it should be in-wall rated. You can get MUCH cheaper than that for arguably no loss in performance.I went with a van den hul clear waters cable enough to wire for 7.2.
This just sounds flat out crazy. If you're building the room now, and you have access behind the walls and ceiling, run wires now. If you think there's a chance you'll possibly be using Atmos in the future just do it now, it will be WAY easier than having to try to snake wires through finished walls and ceiling later.We also touched on Dolby atmos, he told me it's not a necessary to pre wire as it pretty easy to wire ceiling speakers.
I have found this to be true also. The extra 2 rear speakers have added very little to the viewing/listening experience for me. I had higher expectations. I do believe overhead speakers will EVENTUALLY be worth the effort, however.No reason to not go 7.1 but you're not going to gain a whole of a lot compared to 5.1.
