Listening to Apple Spatial audio atmos mixes are like anything else, some good, some not so good. I like "We Take Requests" atmos mix by Oscar Peterson, all of the Beatle atmos mixes, and Kraftwerk in atmos is really good, play it loud and it just pressurizes the entire room.

@Kota1 Say you have a speaker at 135 degrees to your right behind you and say you have a signal from 225 degrees on your left behind you. You can’t perceive a phantom center channel between them but that is how Atmos works, Atmos creates phantom channels that are moveable. To me the only way to fix this is to not have the surround channels symmetric. A much clearer example is where you have Atmos speakers in the ceiling behind you at equal angles they nearly reach your ears at the same time not allowing your brain to position them well at all. Other than using a very dead room it doesn’t seem like there is an answer other than making the speakers non symmetrical, playback would still work because no two systems would be the same about of non symmetricalness, if that’s even a word. What do you think?
@kota1 So I discovered something that I thought I knew but didn't know for sure. In acoustics and photography and many other arts there is something called the rule of thirds, well I panned (actually I entered the info) to have the front speakers ⅓ of the way back and ⅓ of the way in, when I did that it felt like I moved into the stage a bit. It was interesting that when these numbers were exact and my head was right in the sweet spot the effect was very strong. I'm not sure panning in the traditional sense would have achieved the same effect. The only other satisfying speaker position was full blown stereo 100% left and right which felt more natural.
It is an odd thing to set up music this way, I was a musician and a monitor mixer for bands when you are in the listening position and you are facing the band looking at speakers you are engulfed in it but facing the wrong way, even with side fills as a musician is used to it feels wrong.

My room treatments are not symmetric, worked fantastic for me. See "Anthony Grimmani's acoustic recipe.

My room has a setup less than ideal for back surround speakers so I chose a specific speaker that uses a Harman proprietary technology (HST) to deal with it. It makes it seem like the entire back wall is a speaker in my room:

I can't say what will work for you. What worked for me was following the Dolby specs for speaker setup, measuring, treating my room, using a calibrated mic and upgraded audyssey for DSP, measuring, tweaking and listening, until it met or exceeded what I wanted (both objectively and subjectively). Now I just got that tip about top middle speaker placement from the Trinnov guide so I will tweak.

I prefer Fibonacci ratios

Talk about a sweet spot. Some of my favorite tracks are sound board mixes from concerts you can get at nugs.net and wolfgangs.com
