My set up is currently 7.2.4. I love the movies but this post is about the Music. I have a big collection of 5.1 surround sound discs. I don’t collect them, I got them to play them. When I compare my receiver’s Dolby surround logic or Neural X upgrade from stereo, to an actual 5.1 disc, there is a huge difference to me. The 5.1 mix was always better. Now I’ve listened to 5.1 discs digitally upgraded to 7.2.4 through Dolby surround. To me a few were better, but most were not. Aerosmith Toys in the Attic SACD 5.1 was worse. I won’t name everything, but softer things like The Carpenters and Tchaikovsky sounded better. Dream Theater was worse. YES Close to the Edge, better. I've yet to try my Fragile DTS 5.1. Rush Signals in Atmos from disc didn’t seem any better than the 5.1 Signals disc. So is it the type of music that just isn’t good for Atmos? Some Atmos songs from Apple music aren’t impressive and sound like a digital upmix gone wrong. Some are perfect. I don’t think anything can beat Heart Barracuda in Atmos. It tops my list as the best Atmos music I’ve heard. In one YouTube video, Steve Guttenberg says music should only be Stereo. I do know good stereo can be better than 5.1. Some songs where guitars or vocals pan from Right to Left and back, present a key emotion of the song. Then 5.1 versions often remove that, but are good to get more detail from instrument separation from different areas and more emotion when it's purposefully done, like "On Air" from Alan Parsons. which blew me away. So now we have ATMOS! I do feel with Atmos there is nothing better when it's properly panned. It is sometimes indistinguishable where some sounds are coming from, which makes it less about finding the sound and more about the experience. I guess there is good and bad in everything. I would love to hear your thoughts on The Best of Atmos and then why some are just "quick change it to something else!" Again, listen to Heart Barracuda in Atmos!
