I didn't try Atmos or boosting the surrounds - good ideas, both - but I did notice that is sounded somewhat indistinct, compared to the CD I know well, until I freaking CRANKED it. Fairly loud, I was hearing everything I expected, plus elements of the album I never knew were there. And everything sounded well-balanced.I gave this one an eight. Love the music and the surround mix, while certainly not reference, is very serviceable. I play this alum with the Dolby Surround upmixer to ATMOS and bump up the side surrounds a couple of db. IMO, this really helps bring out the surround mix.
I'm not really hearing a muddy mess as others have stated. Not to dismiss those opinions but it 'sounds' great to me.
