Study: Is I²S interface better for DACs than S/PDIF or USB?

Marantz A-10 and newest Yamaha. Marantz is expensive but well-made and has 8K passthrough, an HDMI 2.1 , Dirac and 16 channels outputs . Would be ideal if ;
1. the digital volume was in 32 bits ( I don't know if it is ) in order to not decrease bit depth
2. There was a way to bypass the digital to analog conversion , bringing the digital channels to the xlr,s directly ( analog from the manufacturer)

I think this should be an option offered by the manufacturer as it is in the Datasat AP-25 and Trinnov.
However waiting for this to happen would mean that I would be deaf by then...
So hopefully, there is a way to do it yourself ( if y are good at these things) or have a tech doing it for you.
But, I don,t know how to do that ,so I ask this forum if there is already a solution to this vexing problem as I can,t afford a Trinnov/Storm/Datasat given the low value of the Canadian dollar and Canadian taxes on goods ( 17% in Quebec, Canada).
Best, R
 
Marantz A-10
My google does not seem to find A-10, only AV-10 or AMP-10 or SA-10.

The real-world DACs cannot utilize full 24 bits anyway, volume control at 24bits yields the same result as that at more bits.

I am afraid I do not understand what you mean by bringing digital channels to the XLR - like AES/EBU balanced digital outputs?

Yes, AES/EBU digital outputs with volume .
Also, sorry about the Marantz A-10, you are right I meant the AV-10. I thought that most AV or Preprocessor would take the HDMI audio stream and and amplify it in the digital domain before converting it to analog and sending it to the AES channels in analog. Was wondering ,if it was possible ( and hopefully not too expensive ) to take the digital steam ( before it's conversion to analog ) and route it directly to the AES channels making them outputting digital channels with volume ?
It is because I would want to have in the near future all of my speakers ( 16 or 22 ) to be digital ,like Genelec or Neumann KH 150 and 120 AES67 . The computer would have Dirac live for correction and output to the Marantz ( or any other cheaper product suitable) that would do the digital AES/EBU volume control .
However, the ideal would be a computer with Dirac plus a Dolby Atmos license able to receive the HDMI 2.1 ( maybe 2.2 by then) pass it to a sound card that could then output 16 to 32 channels with digital volume control to the speakers , maybe via a Db-25 or other ? I don't know much about the pro-world of audio except that some card can go up to 128 channels and more . Likely, I would need a lot of time to learn how to properly use such a device and software.
Alternatively, there are 2 devices that appear to make it simpler maybe ; Arvus H2-4D and Audient Oria.


With h2-4d and Oria, one need a computer with Atmos license , Dirac if desired and maybe a video-card if one wants to thinker with video stream .
I would prefer that Prepro came with the option of analog or digital outputs options. Likely it would be simpler ,cheaper and more robust.

So .... What is one to do ?
