Proper format choice

Let's say that I have a 7.1 audio system. I buy a disk that has 3 audio tracks. They are:

Auro-3D 9.1
Atmos
DTS-HD MA 5.1

If my processor can do Auro, Atmos and DTS-HD MA, which is the best track to choose that will maximize the quality of the audio?

Office: Emotiva mini-x A100, Geek Pulse, (2) KEF LS-50, Goldenear FF 4, PC, NAS 130TB

Each of those sound processes has varying speaker setups, so it would be dependent on your speaker positions, i.e. Atmos above the head, Auro requires Front overhead channels, etc., DTS is probably the more flexible of the three, IMHO. Hope this helps, I'm sure others will chime in.

It is a standard 7.1 horizontal plane layout... Left front, Center, Right Front, Subwoofer, Left Surround, Right Surround, Left Rear surround, Right Rear Surround.

If i choose the 5.1 track, the rear surrounds will not be used at all of course. So the question is, are the Atmos and Auro down-mixers worthwhile and trustworthy enough to make good use of the rear surrounds without muddying the original quality and intent of the creator. While less enveloping, will the 5.1 mix sound better because the imaging is not left to a down-mixer?

Then DTS would probably be the best option, just make sure your audio is properly calibrated. You could always test each one and see which sounds better to you, but again proper speaker calibration is important, prior to evaluation.

The Atmos track should decode basically as a normal dolby trueHD track which are usually 7.1. There is no downmixing as such, it just doesnt decode the extra atmos information without atmos speakers.
Atmos can be dolby digital+ based but thats mostly for streaming, not common on bluray.

So, am I missing some of the audio if I choose the Atmos track? This is an audio only disk.

No you wont miss anything. What they do for the last full atmos is more or less move sounds to the upper/top layer. All sounds are in the dolby trueHD track you will hear.

But try them all, all mixes are not created equal so might be one of the others sound better to you on that disc. It may be different on another disc.

They will adapt to fit your speaker configuration, each one in a different way. Listen to all of them and decide what you like best.

I'm not as familiar with Auro but Atmos and I believe Auro require height speakers. You have a traditional 7.1 floor level speaker configuration. If you try to play the Atmos soundtrack, you will get Dolby TrueHD 7.1.

DTS-HD MA 5.1 will replicate the Side Surround channels to the Rear Surround speakers. So you end up using all your speakers.

Not sure what Auro will do

I expect Dolby TrueHD would be the preferred soundtrack.
