I've read about SAM1 to SAM2 profile migration problems. However, for fun, I've tried V8 profiles from 804D3 as well as profiles from other manufacturers such as Focal and thumping is present in all if SAM2 is on and volume is raised to moderate levels.
No thumping on any pre V8 profiles and SAM1.
It will be interesting to see if lowering SAM2 % will solve the problem, once I get the remote.

I have a pair of Vienna Acoustics The Music floor standing speakers. The SAM profile for the speaker just came out a year and a half ago I think. Without the SAM engaged the speaker sounds just fine. Soon as I engage the SAM I get the loud thumping even at moderate volumes when there is a strong bass passage; for instance in the Eagles Hotel California track. It’s an excellent recording in 24 bit 192K which really tests your system thoroughly I think.
I went back-and-forth with the Devialet support team for several weeks and they even sent me two profiles which they said were tweaked and perfected for the speaker. The problem just didn’t go away and I gave up and decided to leave the SAM off. By the way I don’t use the phono stage as I don’t have a turntable.
The other thing is that my speaker never had a V1 SAM, by the time they came out with the SAM profile it was the V2. So essentially I can’t compare the two. I could go back to version 7.1.3 but then a lot of the newer features would be lost that come with the current firmware.
Not being able to engage SAM is a downright shame, because the thumping sound aside, it greatly widens the soundstage and the vocals definitely image better. It’s a pity
Does any one have link or file for version 7.1.3 by any chance?
Thanks

I have a copy of v7.1.3 beta firmware (not sure whether it ever got to a non-beta release). I'd be happy to send it to you if you'd like to PM me with your e-mail address.

After I upgraded my 250 to CI I have not noticed the 'thumping' problem. It was quite frequent and reproducible before. Is this related to 10.1.0 and earlier?
