So I don’t think the issue has been robustly solved, and I think it’ll be a couple of weeks until I’m fully relaxed. However here are the options for the route cause:
1) Incorrect SAM profile effecting higher frequencies and causing ringing that fries the tweeter: as confused says, I’ve never heard of this before, though in the context of the correspondence with Devialet, they seem to be suggesting that SAM can have an effect on the higher frequencies, even if that’s not the intention of SAM. …

I don't use SAM, I hear a difference in the lower mids with SAM and most noticeably with some female voices which become a little heavier in tone. I don't think SAM is actually changing anything in the lower mids but I do think what it does in the bass changes the transition from bass to lower mids and we end up perceiving things a little differently in that area. I really can't see how SAM could make an actual change in the highs but I have also noticed at times that a change in the highs can affect how I perceive the bass and a change in the bass can affect how I hear the highs. We don't hear highs or lows in isolation, we hear them together in music and the combination creates a different perception than what we get when we listen to one without the other in my experience.
Yes this is so true. Biggest difference I noticed in mids was when adding a sub operating below 30hz.
So I can’t perceive any changes in the highs with SAM on - this is just what Dev support mentioned. I’m going to follow up with them for clarification I think.

Just don't use SAM on current firmware version (Firmware 13.1.3 + DOS 2.2.4)! This could endanger your speakers. Please see my previous post here (#19).
Just wait for next firmware version...
