I agree with you. X.0 versions often has errors.  In a follow up response, among other things, Devialet said the following:

snip
..Rest assure that this is only the first version of firmware 8.0, so corrections will be implemented in version 8.1 and beyond....

I'd hope that 8.1 would not be too far away as Devialet is probably getting lots of critical feedback for 8.0.0 at the moment.

However, SAM has minimal effect on my Focal Scala V1. Sound stage opens up a bit with SAM, but not much changes in the bass. SAM 2.0 is even more subtle than 1.0, not sure if it's worth the trouble. I don't noticed much difference changing the SAM % either. I'm wondering if other Scala V1 users have the same experience?

Hello, I have older Focal Utopia speakers, a pair of Diva. Devialet borrowed my own pair to be SAMed, so I hope the correction is the right one!    I have a similar experience, SAM does not change completely the bass, and I think it's because we have speakers with already a good bass response without SAM. However if you look at the boomers while playing double bass for instance, SAM correction can be seen immediately at times, movements of the speakers' membrane have a much larger amplitude with SAM.

Thanks for the feedback Sylvian.

I've seen video's of other SAM'd speakers, like the B&W 802D, on YouTube. It looks like some kind of subsonic vibrations with SAM. Deviate's site claims 10mm excursion for the Scala V1 with SAM, (I thought it used to be 17mm with SAM 1.0 ??). I was hoping to see some visible evidence of SAM in action, but my Scala's woofers don't seem to move in & out with SAM like the others. I've tried it with Subsonic Filter On & Off, but I've not noticed any major visible difference in the woofer's behavior with or without SAM. I usually set the volume at -33dB to -20dB max, may be I'm not playing them loud enough?

  Well, I am quite surprised. On the video, the tune played is track 4 of this album http://www.qobuz.com/fr-fr/album/jacques-loussier-trio-the-best-of-play-bach-jacques-loussier-trio/4892843002596?qref=dac_7 (Gavotte in D major). I just tried at -20 dB the beginning of the track, SAM ON/OFF is obvious, the woofers move much more with SAM ON (100%) and if I reduce SAM %, movements of the woofer are smaller (subsonic filter OFF, I did no try with ON). I know that there is a big woofer on the Scala and 2 smaller woofers on the Diva, but B&W 802D has a big woofer too. I remember that someone who have a pair of Focal Diablo (one of the first speaker SAMed by Devialet) noticed these big movements too. What source are you using?

Thanks, I'll try that one out. I used Massive Attack's "Angel" to check SAM On/Off before, which is the reference track on the Scala V1 SAM webpage.

I made a test : I converted the lossless flac file into MP3 (Gavotte in D by Jacques Loussier). Even with MP3 file, SAM can be seen without problem.

As you've mentioned, I didn't noticed much change in the bass with SAM. The most obvious difference with SAM is the slightly expanded sound stage in my experience; and SAM 2.0 is even more subtle than 1.0. Maybe my hearing range has diminished at the low & upper end with old age.

Jeff Fritz, Editor of Soundstage.com, once evaluated the expert line (of course not V8.0.0) and said it was dead silent even in his sound-treated listening room. So what comes the problem of the low frequency heart-beat-like rumble and the sudden outburst of very loud noise we heard? Electrical interference from our home electricity network? The later firmware? Or any other factors? Saint0 did you plug the Expert line direct to wall socket or use a power conditioner?

I'm pretty sure power is clean. D250 is connected to PS Audio P5 with Shunyata Z-PC10 power cord, and the P5 goes to MIT 20A in-wall conditioner/surge protector. I'm surprised to hear the low frequency rumble & beating noise, as well as the glitches with SAM 2.0; both happened after the V8.0 update. Unit was clean and dead silent running V7 prior to the update.

I've contacted Devialet, they're supposedly looking into it. This is the first time I had problems with their F/W update.

I don't want to experience noise problem when supposingly  playing the most advanced amplifier in the world. Hope Devialet acts fast. All in all, the views towards V8.0.0 are dividing.

Turned my D400 up to plus 30 dB last night and there is absolute silence on all the inputs - except phone for obvious reasons, I even asked SWMBO to listen as well just in case I had gone temporarily deaf due to the volume !!!

The poll on this forum would tend to disagree
