Are more details about DOS3 and hardware changes available?

[Guqin_32]

1) The processor on the new Phantom Ultimates is listed as NXP i.MX 8M Nano which based on 

https://www.nxp.com/products/processors-...MX8-SERIES

comes with 64-bit ARM-A53 cores whereas previous generation had 32-bit ARM-A9 cores. I don't have the details of the SoC from the prior generation to compare these side by side, so insight on that would be helpful. What I'm looking for is whether in terms of processing power the new generation will have room to support things it doesn't seem to have support for out of the box like surround sound / multispeakers beyond just stereo. I couldn't find other details like size of RAM on new generation

There's no DSP on the new generation's SoC, I wonder if the speakers may have a dedicated DSP chip outside the SoC or do the processing on normal processor cores?

2) Is the standard TOSLINK optical input port replaced with a mini-TOSLINK 3.5mm round port? That's best guess from pictures and what's in the 2 page user manual.

3) I recall during upgrade from DOS1 to DOS2 there were a ton of communication from Devialet about feature updates, what works, what doesn't and what will be addressed in future revisions. I haven't been able to find anything of sorts regarding DOS3, how it compares with DOS2, will it be only available for the new generation devices or will any of the older devices be able to upgrade to it and what would the consequences be.

DOS3 is only available for the new generation devices, and I doubt that will change.

As for the inputs, did you see the "compare speakers" page? https://www.devialet.com/en-us/phantom-speaker/compare/ It looks new, I do not remember seeing it before! Very well done, too. Anyway, it says 1x TOSLINK (optical) for the Ultimate 108 and 1x mini-TOSLINK (optical) for the Ultimate 98. So I guess it's standard on the big ones and mini/round on the small ones, as before.

Hm there are some 'new' features with Dos 3.1.2. FIRMWARE (As reported by the DOS API as "available features" not found on previous gen Phantom speakers)

-Chromecast 
-standby
-streamQuality 

The 'device web app' configuration web page is updated, UX is new has a new function to set the startup volume, and an option to select channel mix as Left Front, Right Front, or Mono. As well in the app for the Ultimate some Sound options and settings that are new.  Thats probably the biggest change so far, the Android App updated and looks very different and has some new options for the Ultimate.  for some sound settings, tunings, profiles.  from an android device, Chomecast  just worked as the output from an android to the Ultimate 98.. that was kind of nifty...(but still only 16/44 near as i can tell)  

For me so far DOS 3 just worked with existing APP using the DOS2 (IP Control interface v1) [i use this: https://halrad.com/slPhantomRemote/]

Out of the box updated Firmware - Restarted and so far, just has just worked as expected, via ETHERNET.

it showed up as an IP control endpoint and so far, works better (Ultimate98 seems a bit more responsive) than the Dos2 phantoms from an IP control standpoint...

and the Ultimate 98 optical is a mini-Toslink (round) 

So far so good on what i have tried (chromecast)....and optical.  mono and stereo. 

though i would miss the Dialog/ARCH but not sure if i will, though that is a HEAD SCRATCHER the old sources are not supported.  engineering team, you can do it...

i guess the realities is MANY (most even) probably just have nothing LOCAL and STREAM everything so it works. (meaning they can get away with it) probably some challenges in using the old code too... it all had to be PORTED to the new CPU for sure.. 

FWIW i have never seen the arch outputting anything other than 44/16. (as reported by the Devialet API)
but the Ultimate98 via SPIDF reports it as 96/20 (as reported by the Devialet API) probably not new but since my phantoms are on the wall and a pain to move never put the optical cable in... 
so far noted these operational differences:

interesting the optical source is being reported as 20bit. (not sure where that 20bit is coming from yet) ... i think the source is 96/24 and its saying 96/20.?

Bluetooth shows x2 up for both endpoints in a pair. as in i see both LEFT and RIGHT Bluetooth sources but not tried to use either.
