Sorry for chiming in this late.
Following the discussion here leaves a few questions about using SAM.
Firtstly, how are the SAM curves for the individual speakers established by Devialet? Since the room and speaker placement influences so much the sound, the curves must have been established by measuring them straight on the speakers, that means the mic points onto the woofer, correct? But doing it in this way, couldn’t this also introduce time incoherence with, say the the midrange driver/tweeter? Or are the SAM curves taken in an anechoic chamber?
Secondly, if SAM can kick in some room nodes, so why doing it altogether? I know one has to try, but to me the concept seems to be too much influenced by the speaker‘s environment.
Thirdly, I am asking myself how room EQing interferes, or is influenced, by SAM. Most rooms need some EQing in the range between 100-200 Hz, and, remembering Devialet‘s statement, that’s where SAM kicks in.
I did try SAM (40%) with my speakers (ATC SCM19) but it was strange in the sense that in most cases, I couldn‘t hear much difference, but in a few cases it kicked in and made the bass over-represented to an extent that made me jump. So in the end I disabled it altogether.
