There is a big difference in the beggining of the album, from original stereo and Quad mixes to new ones.Sounds fantastic, but for now I wouldn't say it's deserving a 10 in Atmos category of mixes. As a 5.1 is really good, but for any reason I find it lacks something in Atmos (but please don't get discouraged by this very first impression).
I'm still on track 2
The older mixes have loud, bright piano right up front. Thew new mixes have lots of reverb on piano so it is far away/ in background. Quite a departure.
