After using 7.1.3 for a few days, I swapped to 8.1.3 (beta) and believe that there is more bite, slighter better bass and clearer highs. Just spent a few hours listening to everything from Goldfrapp, Melanie De Basio, Air and Shelby Lynne and feel its just more involving than 7.1.3. I used the same configuration file with no DPM and no SAM (my speakers are not SAM friendly).
Going to stick with this for a while and might try swapping for the official 8.1.3 to compare next week.

did you use the same configuration files as for the official 8.1.3?
Yes, same config file

The rumour about amused Devialet people is a good one, maybe more of a fact
It's like engineers fixing the headrest of a car, and the customers claim that the car is driving better (or worse) and faster than ever.
I am sure Devialet's engineers are simply stunned and laughing about "audiophilia nervosa".

I'd say this rumor is worrying. If the engineers at Devialet can not hear the difference between, for example, 7.1.3 and other versions it is a problem. Then we can not rely on Devialet to create a specific quality in a newer firmware if they wanted to, simply because they can not hear it and hence do not know what created the difference..

Looking at the curves (http://fr.devialet.com/enceintes/atc/atc-scm-40) to my surprise I noticed that in comparison to a lot of other speakers that had already been SAMed,my speakers
sound pressure diagrams were almost identical or didn't correct much.I don't know if that means that my speakers are that good or SAM doesn't offer too much for my speakers.
Let's go to SQ now:
I agree more than 100% with what aisip Wrote:
"The series 8 FWs (all of them) sound clinical and hifi-ish in comparison".
Every firmware after 7.x.x that I tried including 8.1.2 and 8.1.3 with my speakers SAMed do not compete firmwares 7.x.x without the SAM feature in my speakers.
As I wrote in a previous post sound is hifi not hiend which also aisip wrote which absolutely explain the fact for the review here:

The poor guy tested our beloved Devialet with 8.0.0 firmware... and the comment by Frederic says it all:
""Attention le firmware 8.0.0 était moins bon que la dernière évolution du 7.
Le firmware 8.1.2 corrige les défauts que vous évoquiez" - traduction le firmware 8.0.0 était mauvais, le 8.1.2 est un peu moins mauvais ?
Je suis très sceptique... Cela me semble être une belle excuse pour affirmer que le produit n'est jamais testé comme il se doit... Devialet tient plus de l'informatique que de la Haute Fidélité, je me vois mal être client de cette marque et vérifier tous les deux jours si le concepteur a décidé de sortir une énième mise à jour, c'est pire que Microsoft et son Windows. Sachant qu'à chaque mise à jour le produit sera différent, quid de mon choix de départ affectué après de belles ou moins belles écoutes chez mon revendeur préféré ?
Une seule option, pour les "bobos", achetez Devialet les yeux et oreilles fermés, de toutes les manières la musicalité des produits de cette marque est très insuffisante et ce n'est pas un firmware non vérifié et non contrôlé qui va changer quelque chose... Attendez le firmware 12.2.1 avant de vous faire une opinion..."
and by using Google translate:
""Beware the 8.0.0 firmware was not as good as the latest evolution of 7.
Firmware 8.1.2 corrects the defects that you mentioned "- the translation was bad firmware 8.0.0, 8.1.2 is the slightly less bad?
I am very skeptical ... That sounds like a good excuse to say that the product was never tested as it should ... Devialet takes over the computer as High Fidelity, I see myself malaise customer that mark and check every two days if the designer has decided to release yet another update, this is worse than Microsoft and Windows. Knowing that each update the product will be different, what about my original choice after affectué beautiful or less beautiful plays at my favorite retailer?
One option for the "bobos", Devialet buy eyes and ears closed, in every way the musicality of products of this brand is very inadequate and it is not an unchecked and uncontrolled firmware that will change anything ... Wait 12.2.1 firmware before you have an opinion ..."
So let us hope and wait for 12.2.1 firmware...
This explains some things at least for my speakers
I sent an email yesterday to Devialet support:
Dear Sir,
I see that recently you have added SAM feature for my speakers and I thank you for this.
By observing the sound pressure diagrams (
http://fr.devialet.com/enceintes/atc/atc-scm-40) I notice that the diagrams are almost identical.When I observe sound pressure diagrams of other manufacturer speakers with SAM in the list I notice big difference between sound diagrams without SAM (before) and with SAM (after).Just out of curiosity what does that mean?
Are my speakers that good or the benefit of SAM to them is negligible?
Kind Regards
and the answer today:
Devialet Support (Devialet)
Dear Sir,
Thank you for your message.
We reached out for Maxime, our SAM engineer who toured in Asia last month with his SAM LAB, and did the SAM profile for the ATC SCM 40.
He clearly remembered the ATC SCM40 and
he stated that it is an impressive loudspeaker.
The performance were already good without SAM, and with SAM it became one of his personal favourite.
However, please note that while the sound pressure curves can give an idea about loudspeaker performance,
it is not an absolute criterion on which one can compare one loudspeaker to the other.
Best regards
Then they must be hysterical about my complaints of slathering the floors, walls & ceilings with magnetic & thermally inefficient 'bling' while simultaneously coating all binding posts and inputs/outputs with magnetic material which is fine with me... their future's riding on it, not mine!
flyer - you got a decent reply there! I logged a ticket a few days ago saying SAM for my Raidho C-1.1 has been rather unimpressive since the 8.x firmware came out and the reply basically was that no-one else has reported any problems, and because SAM v2 is better (the speakers were done when SAM was v1) then they will sound better than with firmware 7.x. Also SAM v2 adds protection to the speakers. Well hang on, I though SAM v1 did that too? And is SAM v2 better sound quality? It's now marginal with my speakers whether SAM is actually adding anything positive and I'm listening more and more with it off, and only 0% SAM if I have it turned on.
Anyhow going back to firmware, Linn and their DS have the same shenanigans each time a new firmware comes out and have done since they brought the products came out quite a few years ago. I have to admit I found most of the Linn firmware sound quality differences more subtle than the Devialet ones, but still many people swore blind there were differences and Linn denied any possibility of it, though occasionally an engineer would sheepishly confess they could hear a difference. Interestingly Linn DS is built on a similar platform to Devialet with FPGAs where it's possible to change the circuit topology of the processor so there's an added layer of complexity over a standard processor there.
The 8.1.3 beta and 8.1.3 official is a good example I think. I confess I'm a fruitloop and loving 8.1.3 beta but 8.1.3 official is giving nothing extra to me over 8.1.2.

Maybe this is why the Sound Quality has meandered from FW release to release.
Who listens to rumours?? Plus it is quite possible that NickB has been at the Cider again .........
Please...I think he just made that "little rumour" up to get under our skin.
edit: it seems Confused beat me to it, just mere seconds!
