That wasn't my question. Haha.
Then you’re asking to compare the best Atmos mix to best DVD or SACD?
I’m a big fan of discrete mixes and there’s not many discrete Atmos release yet (or for that matter, many Atmos releases at all). So I’d be comparing a hand full vs a truck load. Also content is king, and my favourite surround albums aren’t in Atmos either. Content is a big influencer.
Short answer: Currently I get more out of my best 5.1 and quads than my Atmos albums.
But I still stand by my original comment. I’d rather get an Atmos new release than 5.1 if I had a choice.
