Oppo 205?

HDMI Audio: up to 7.1ch/192kHz PCM, up to 5.1ch DSD64

HDMI Audio: up to 7.1ch/192kHz PCM, up to 5.1ch DSD64

So, 768kHz and DSD512 are only for stereo - I see. Thanks and good luck with your project.

good luck with your project.

Thanks

2. Routing. I would want to assign specific channels to specific DACS
...
5. The Driver needs to output to USB, and since we're talking multiple dacs, it would need to output certain channels to one usb outlet and others to a different output, and do it in LPCM, of course.

Correction to the previous answer.
All of this can be done as well.

Could you elaborate a bit on the formats you list on the thread title? Because I only see mentions to DSD so far in here. And while DSD is nice and all, you can easily play it back without losing anything important (imo) with a number of existing solutions. Atmos and auro 3d without an AVR though, now that's fresh and exciting. Are you using cavern for conversion?

Indeed, there's been too much discussion about DSD; it's just that people have been asking about it a lot.
But as you rightly noted, the topic is about multichannel music without an AVR. It's funny, but right now I only have a stereo amplifier and a couple of speakers. But I really wanted to hear Auro-3D. A friend asked if it was possible to replace the AVR with stereo DACs so could use high-quality amplifiers. So I took on this project.
Currently, I have five DACs, three different and two identical, which were sent to me. There's a working version of an app that outputs two stereo streams synchronously to two DACs via ASIO. Unfortunately, ASIO only allows simultaneous use of DACs from different manufacturers with their native drivers. So I switched to developing an app for WASAPI. I've already developed one for two DACs and tested it with both different and identical DACs. Now I'm working on four DACs. There are certainly many challenges, especially with the parallel operation of multiple native audio engines. Dynamic synchronization of audio streams is also a big headache)) And yet I hope for a positive result.

Some do, others don't. What I know from my education, knowledge, and practical experience in research and development is important to me, but I'm not trying to convince anyone otherwise.

You are trying to create a product to sell to 'audiophiles'. I get it.

That's not true. There will be no product for sale as a result of this research project. Ever. For anyone. Although I hope that eventually I'll be able to build an Auro-3D system for myself. And I'll help my friends do the same. I'll also share on this forum what's possible and what's unlikely. Knowing what's possible might inspire others to do something similar or even better.

In that case your great concern with sighted audio ephemera is not explained.

5.1-channel audio playback with 3-stereo splitting, upsampling and synchronous output via WASAPI Exclusive to three identical DACs.

A side branch of research: a small application for playing CD rips. It uses 64-bit sinc interpolation up to the maximum multiple of the active DAC frequency.
