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'd like to add that V8.0 is running OK under "nominal conditions" playing music at -33dB to -20dB. The operating temperature is 4 to 5'C lower than V7.1.1.

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?

I used chrome. I love this product but the software is a pain.
Btw does anyone know how to unselect sub/pre out for inputs? Mine are grayed out.

Yes, if you use Safari, and have logged in and try edit your old confiriguration file, it fails when downloading and give error. If you dont login and start from scratch, it works.
To edit old conf-file without  download errors, use Chrome
