It's not intended or designed to modify or correct room caused frequency anomalies which is what systems like ARC, Room Perfect, and Dirac are intended to do. SAM can't do what they do and they can't do what SAM does. SAM and those systems are designed to address different problems and Sweet Room, not SAM, is the room correction system Devialet has implemented in order to do the same sort of thing as ARC, Perfect Room, and Dirac do.
Yes, SAM is not a room correction as well as Sweet Room that is a nine bands parametric equalizer.
DRC (I use Dirac in my system), is something completely different that also intervenes on the phasing and the gain of the speakers.
Looking at measurements posted by the opener, SAM modifies heavily the frequency response of the low end. I would be curious to take a look to the spectrogram with SAM 100% and without.
