Agree 100%. If you think as front to back as anchor points, adding another overhead speaker in between them stabilizes the imagery more.
Speaking of .6, out of curiosity, over the weekend I did a test of a front height/top front/top middle .6 setup to determine how much separation there was between content on FH and TF (no remapping), using the first scene in Rampage set on a space station. With a FH/TM/TR setup (my current layout due to overhead angles), when I soloed the overheads, the breathing of the scientist, rotation of the station, and structural/metal sounds tend to be up front above the mains.
However, when I kept my FH where they were, but switched my TM to TF, and TR to TM on the Atmos speaker configuration, you could better separate out the rotation effect and the breathing to be separated, with more discrimination across the front around to the wides above the speakers. Very loosely, kind of like "stereo" vs. "surround" above and in front and to the side.
Granted these are #firstworldproblems
, but now I'm thinking of putting a pair of overheads between my Front Heights (about 30-35 degrees) and Top Middles (about 80-85)
in the 50-55 degrees range. The only downside is that I'll have to free up channels on the Altitude, since I only have one channel free of my 24 right now. I'll have to offload the individual subs from separate channels managed by Trinnov to management on a MiniDSP or Xilica (not sure I'd want to spend for the Q-Sys Core).
Of course, that opens up more possibilities - a second pair of rear centers (LOL) or if I seriously cared about Auro (further LOL), surround heights...I know some won't agree, but sometimes quantity has a quality of its own...
I think Adam is running 13.1.8 in his Lab for Atmos, but that could be counting Auro-specific speakers as well.
I do like the wides even though there is not a ton of material that uses them effectively, but my preference would be the 6 overheads first. If you decide to do wides later its easy enough to matrix your side surrounds into the wides when upmixing to give them something to do.
Or the mains copied to wides at a lower level. How much IMO that works depends on your room.
