13.2, 5.1 and so on. "the best seat in the house"

This is why there is home theater and two channel audio for music. Completely different experiences. 
 

While it is true live concert hall venues have reflections from the sides and behind… the degradation of signal by incorporating all those extra channels are generally not worth it. So two channel audio is by far the best for music… concerts.

Movies… bullets flying behind… 5 or more channels sound great. You are distracted by the video so you don’t knotice the poorer sound quality. 
 

I have a separate 2 channel audio and home theater… you can see them under my UserID.

I tried for years to use a 5.1 system for stereo, spent big money on speakers and electronics (Macintosh-Anthem-Lexicon), that had "2-Channel Stereo" as an option, never sounded good unless video was playing. Finally gave up and got a nice two channel dedicated system for way less then what I paid for the 5.1 system. Glad I never tried to go up to 7.1 or 9.1 or whatever they are up to now to solve the problem.

Actually I went through the same song and dance until I bought an integrated amp with a home theatre bypass option. This allows a AVR that has the ability to pre out the front channels separately to use the integrated to power the front left and right speakers in a 5.1 system.

Best of both worlds.

When you get a system that replicates a live performance start a new thread. Until that happens it is ALL BS. Everyone buying it, everyone selling it KNOWS it ain't a live performance. It is simply how you like your BS served, with two speakers or 22, take your pick.

When you got 22 speakers you serve your BS in stereo, surround sound, or immersive. When you only got two speakers you got no options, take your BS straight up and that's all she wrote. 

I get a glimmer of reality when my wife plays piano, beyond that LOL.

FWIW, I watch concerts recorded in high definition in Dolby Vision on my 120 inch screen while I am listening in 9.2.7 immersive audio and I still know its BS. Good luck with two speakers pointed at your head, you can smell that BS from a mile away with your eyes closed. At least I can see what they were doing when it wasn’t BS and an actual live performance.
