I know the thread name won't mean much to most of you, but all that talking about McIntosh capable decoding of 360 Reality Audio is not that clear to me.
Sony and McIntosh claim that the MX123 is capable of doing that, but how?
I know that Tidal or Amazon Music could let us play that format only via headphones and smartphones, which means nothing to me.
The "old" simulated surround thing is like spending 100,000$ on a perfect mixed song at 384khz or even better only to hear it at "full quality" at mp3 128 joint stereo
I'm asking myself, and maybe Sony and McIntosh, how I can enjoy 360RA on that 15,000$ receiver.
I know for sure that Tidal/Amazon/Deezer stream those files in stereo with no real bitstream.

I suppose it could be done via HEOS but actually it's not.

I also downloaded the user manual from McIntosh and there is NO mention of 360 or MPEG-H, so no luck.


BTW, I forgot to say I'm a proud owner of a Marantz SR7015 that could handle mpeg-h audio as well but the question remains the same

the failure to get 360 Reality Audio decoding into more gear other than a couple of their own Soundbar and wireless Speaker systems is really quite palpable at this point.

also (and i'm not complaining about it but it is intriguing!) how comes Sony's Quad and 5.1 offerings on Apple Music are in discrete (albeit Lossy) Dolby Audio and not the 360 Reality Audio format as they are on Tidal, Deezer, Amazon, etc...? 🤔

Well, it wouldn't seem quite right if there were no format wars going on now would it. Apple and Tidal/Amazon just had to do things differently and likely slow the rollout of proper quad streams even 50 years after the fact.

I can stay positive for now just knowing some very difficult Q mixed masters to license have now appeared. Some of my most desired quads finally did show up. We'll get there.

Anyway, 360 RA is a process that can create a spherical effect on headphones, just like Apple Spatial Audio. The stream of the 360 material is encoded in MPEG-H that McIntosh and Marantz/Denon should manage (but they don’t. I never read or see any test about that feature). Actually the 360 RA material is available only on apps via smartphones or pads, IIRC.
Once apps are implemented in some form in those receivers MAYBE we will hear it in multichannel as it was created

Out of interest...

Can those of you with MPEG-H capable AVR's try playing the attatched (zipped) 'MPEG-H Test Sample' via a USB flash-drive and report if it works?

I have a Marantz SR7015 which added MPEG-H (360RA) decoding through a firmware update. But it only accepts/plays stereo through the USB input infuriatingly! Same applies with FLAC/WAV/DSD etc...

This is the issue right now. There is no software that can pass MPEG-H through and link up to compatible hardware. It's bloody annoying. I've tried to ask J River about implementing it but they don't even do Atmos audio files so not holding my breath. @HomerJAU has tried to reach out to KODI developers to see if they could implement it there, but so far not had anyone engage. You'd think something like Roon would look at it considering the retail price.

There is the MPEG-H production format player from Fraunhofer IIS but that would only accept the BWF/ADM master file rather than anything from Tidal etc...

Hopefully something changes soon... 🤞:)
