Does it worth a upgrade to Dolby Atmos?


It seems Dolby Atmos is getting more steam recently. I have a 7.1 set up with Krell S-1000 processor and C-J multichannel amp. The sound quality is great. S-1000 doesn’t support anything beyond Dolby Digital. I am wondering if it worth to upgrade to Atmos processor (eg. Marantz AV770x, Anthem AVM60 used ). I don’t want to sacrifice theater sound quality ( I have dedicated 2-ch system for music listening. so I don’t care 2-ch performance). I have 4 ceiling spks and i can add 2 floor level surrounding spks w/o issue. That will give me 5.1.4. I have used Onkyo, Rotel, Krell Showcase and HTS before S-1000. HTS or S-1000 are big step up from Onkyo and Rotel. Will Marantz have same performance as S-1000 on home theater listening? I don’t want to spend over $2500 for the upgrade. Thank you.

Beyond yes! Atmos is to home cinema what 5.1 was to Dolby Prologic , the upmixers will even take a standard TV show and breath new life into the audio. No 5.1 processor no matter it's pedigree will outmatch a properly setup native 7.1.4 or 5.1.4 playback system.
Do it!
ATMOS is the first 3 dimensional playback format that has music creators excited.  There is a ton of work going to remix records into the ATMOS format.   For film, ATMOS makes perfect sense to create motion, create the environment and space.  For music, it is a creative opportunity for composers and mixers alike.  I've heard quite a few mixes in ATMOS that were mind bending. Abbey Road remixed in ATMOS by Giles Martin is like hearing it for the first time all over again- so exciting!   Amazing experience if played back on a proper discrete channel ATMOS rig (not a sound bar that says it can do ATMOS).

Where can I get Atmos music downloads ?

Tidal has some , I am a subscriber but I would need eArc feature on my processor.
I do not have a BlueRay player.I have Apple TV 4K.
I’ve used receivers as prepro’s since the begining dolby surround mid 80’s. I have never seen or heard a reason to do it any other way.
My 7.1.4 system transports me with the right soundtrack, even that Atmos that AppleTV sends to my Denon. You got me thinking maybe Tennet tonight 

i have a seven speaker diy build from HT Guide for the surfounds and mains, little SVS satilites for the Atmos channels.

def worth it when done right
