That is interesting and new over the previous SAM version. Why would you need a SAM profile for the left and right speaker to be identical unless this is the pre-requirement for future room corrections maybe?

I don't think it is for left and right speaker as the values are different for both value sets. I think it is for bass (SAM V1) and for a new additional correction of the upper frequencies.
Otherwise my left and right speaker would now sound totally different...what they do not of course.

  
I tend to not agree. See below the SAM values. Assumption I do is that left column is left speaker, right column is right speaker. Why? Prior to the SAM fix only the left column was in the config file. After the fix the right column was added (actually it is in one list but for convenience and comparison reasons now in columns) as a result we also had sound in the right speaker. This was the only change they made so good reason for assuming.

SAM values, although with an offset are identical for left and right. Why have a separate SAM profiles for left and right speaker? In individual measurements this may correct small deviations in left and right speaker but these are generic profiles for a specific speaker type. From a room correction perspective this would definitely make a lot of sense so this could be a first step towards it.


For SAM v1 the profile is also still included in the config file logically for 'legacy' support. The old SAM only uses 64 values (for both speakers I'd say).

My guess is that adding a separate lookup table for each speaker may be a preparation for room correction.

'The power supply adapts continuously to the music playing for greater energetic efficiency..'

I'm trying to decipher the quote above. If all it does is save power by varying the power supply depending on the music, i'm not interested. If it actually improves/increases sound quality then i'm definitely up for it..

Is there any further detail anywhere regarding the new changes?

DYNAMIC POWER MANAGEMENT:
Dpm on:
Normal music: 26W / silent turned up to maximum volume: 49W / Standby:  12W / Off: 4W
Dpm off:
Normal music: 26W / silent turned up to maximum volume: 49W / Standby:  12W / Off: 4W
So, no differences at all! Can anyone confirm?
 
TEMEPRATURES:
Remarkably lower compared to 7.1.3 while listening at normal volume (-38db to -20db, in my case). I’m talking about 5-6°, a difference that you not only can see on the sensor readings, but something you can immediately feel when touching.
 
SOUND QUALITY
Without SAM enabled, the chances to 7.1.3 are subtle. Maybe a little bit smoother overall and maybe a little bit more detail and loudness at lower volumes. But probably I wouldn’t be able to tell the difference in a ABX-Test, I have to be honest here.
 
INTELLIGENT CINEMA MODE – HOW DOES IT WORK IN PRACTICE?
While playing normal music, enabling it immediately reduces the volume by about -2db. This can be clearly heard, also when I “blinded” myself if it was on or off. While playing a movie or a FLAC-File with a conversation (not singing) the volume stayed exactly the same, if I pressed the button or not. I immediately thought it’s just a kind of dumb equalizer, maybe boosting frequencies between 125hz and 500hz, but this is clearly not the case. I generated test tones for all kinds of frequencies  and tested the effect of ICM, there was always this volume reduction, also for sinus test tones in the human voice spectrum.
So my theory is that it is indeed a kind of “intelligent” algorithm. But actually working in the opposite direction by slightly reducing the volume when no voices are detected, instead of increasing the volume for voices into potential clipping territories. I think it was a clever idea of Devialet because it is not deteriorating normal music and the effect is not exaggerated. But please Devialet, just let me assign ICM permanently to my optical input only, with which I’m watching all my movies. No need of having a button assigned on my remote control.
 
SAM
Since my speakers (Boenicke W8) are not SAM profiled, I should probably not talk about SAM at all. But since I’m curious I have tried different SAM V1 –Profiles on them in the past and have done so now again with SAM V2. Here I have heard big differences between the firmware versions, mostly reducing the bass boost effect in the new firmware. For my speakers the bass boost effects of other speakers profiles are way too much, and since my bass driver runs without crossover, my speakers probably wouldn’t benefit from SAM either to correct crossover weaknesses. A little more bass (+2db) below 50hz sounds nice, but is not really necessary with my speakers.
 
REMOTE CONTROL
If you assign ICM to the tone button, then treble and bass will be automatically available by a long press on the mute button.
 
Happy testing :-)
