Interesting posts so far! If most of what has been said proves to be the case in my system, I think I'll very much like 10.0.2. However, I do have a policy of only changing one thing at a time, with a significant change I like to wait about a month before doing anything else. If you change two things, then notice something in casual listening, you might never know what exactly caused the change. Anyway, I added a Mutec to my system last week, so I will need to stick the inferior old firmware for a week or so yet.

I was taken aback with the sound-stage thing....
It is surprising how our brains 'fill in the gaps' when observing or listening... you don't notice it happening...
Comparison is the only method that can show up what we perceive as deficiencies between systems or setups...
so.. Mr Confused... methinks you are in for a treat!

It did not sound right in my system. I went back to v8.1.3 and immediately felt it was more natural with fuller bass textures and extension.
When v10.0.2 came out many people were saying it was just v9.01 with added tricks for the newer models. However rather than dismissing it without listening 
I thought I would try it at the weekend.
This is indeed different to v8.1.3. Soundstage more forward of the plane of the speakers - lots of air and sparkle but in no way aggressive or toppy (like 9.0.1). In fact I would go as far to say that this is the best yet in my system in that regard.
I think overall the bass is less extended than v8.1.3 however it has a bit more poise and grip - maybe v8.1.3 has less control? (this is minor and I suspect personal preference). I will need more listing but I'm pretty sure v10.0.2 holds a tune better - maybe more controlled bass. Kind of reminds me of the bad old days of my valve pre-power combos - balanced or unbalanced interconnects? The former gave bigger bass but could sound a bit diffuse, the latter had more control and rhythm but less extension - drove me nuts (thank you Devialet - 1 box and no wires!)
I've noted that some people are now having issues with ROON AIR3b. Me too. Plays no problem after start up but if I change source and come back to it later I can't get AIR and ROON to talk. Think I've found a cure (well, it has worked twice....) - start playing a track on ROON (no sound) then cycle through the sources on the Dev until you get back to WiFi input. The Dev then spends its usual 5-10 seconds locking on to signal and hey presto sound! Again, I've only done this twice and it worked both times.
Anyway, I like what I'm hearing with v10.0.2 and will persevere.

Follow your post I decided to upgrade to 10.0.2 .
From reading your post I understand that we had the same experience , As I am also back always to 8.1.3.
So I upgrade to 10.0.2 (30m ago) , One good thing is the low frequencies problem I had when I upgrade to 9.0.1 is disappear .
Initial listening to 10.0.2 is more "Audiophile" way ..it has more sparks on the highs ..and the lows are more controlled but more aggressive .
Somehow I love 8.1.3 in a way that on my system it sound more 'tube "like , definitely more "softer" then 10.0.2 . (Maybe 8.1.3 has less bass control but for me it has more spirit )
I am not sure that I will stay with 10.0.2 but surely I will give it a try .

We've discussed/hypothesized before what the IHM, which probably stands for 'Interface Homme Machine', does. I consider it the central 'brain'/director of the Devialet and it at least is responsible for the 'GUI' so the display contents and functionality in enabling/disabling functionality. Any changes in SQ (when one doesn't use WiFi and perhaps ethernet) must be because of changes in this file (or the placebo effect of course ).
The jury is still out for me as well. I too am a little more than skeptical when intangible gains are reported but the tangible evidence does not seem to support it. Tightly controlled evaluations are not trivial and they can be difficult to execute precisely.
looking at the online detailed specs of the 130 Pro vs my 120, they look almost 100% identical,.. From the dac to the master clock etc nothing appears to really have changed. I'd laugh if all the improvements to ADH etc where all implemented in the firmware (v10.x)
... remember as well that all the touted lower THD specs of the Pro series is all based around the '4x' improved control loop between the Class A amp and Class D in the ADH... that the 'algorithm' has been updated from 8bit to 10bit (256 levels --> 1024 levels, hence the 4x multiplier) ... This algorithm in the control loop is a software implementation...

OK. This is massively frustrating. How about telling us what you've done, why and why the hell we should upgrade? Nothing at all on the support site that I can see except a download link.
Hello
After some listening I decided to return to 9.0.1
IMO firmware 9 offer more analog sound than firmware 10. Listening give me pleasure for many hours. With 10 sound is thinner, crisper, bass is very tight, for me too much. There is a lack of sound aura around music notes. Music is faster, but more digital.

Well my very new Mutec has definitely sharpened the stereo imagery / sound stage. So this is a good example of why it's best not to change two things at once. I can wait, you're not going to temp me......
