All true.
First I must say, Mountain Jam is The Allman Brothers Band at perfection, a purely great piece of music.
I think between the 5.1 SACD and this Atmos mix they are two different listens.
With the Atmos mix you get no better or worse than the 5.1. Everything seems equal to me.
1. The Dolby Atmos signal is very strong in the heights which is good. but if you could imagine take a block of wood say 4" tall and trim 1" off the top and put that in the heights, what you get is a mirror image of the bottom surround, albeit weaker.
I know this because I turned off all my floor amps just leaving the heights on and that is what I heard.
2. So it makes me wonder for Eat A Peach, I think the listening experience of the 5.1 SACD would be a little better as nothing is taken from it.
3. As Dave~~Wave said and I will add this Eat A Peach Atmos is definitely a keeper, even if you have the 5.1, I like both versions as they are different experiences. Atmos done well, not always has discreet placement of the music, vocals/instruments, but the envelope of sound can be a great experience
