Guillaume, I could not agree with you more, especially, as far as classical music is concerned. I spent hours testing with my Cremona M speakers, switching SAM on and off, to the point of not remembering the current setting (so, this was pseudo blind testing

(I disabled SAM in the Configurator, but noticing that the config file still retained the SAM settings for Cremonas, I hoped I'd be able to turn SAM on when desired, if I left one of the Remote's buttons to toggle SAM on/off. No such luck: if you disable SAM through the Configurator, you won't be able to turn it on by a button press - the music goes silent.)
BTW, for those who prefer to listen with SAM on, you should upgrade to the new version of Firmware 7.1.1, which allegedly fixes SAM temperature issues. I noticed my 250 was getting very hot to the touch with SAM on.
Finally, let me again mention that (at least, for my speakers, ears, and the type of music I listen to) the differences with SAM on and off are very subtle. That's why I consider Devialet's statement about the "SAM revolution" (on par with their ADH technology) an unfortunate exaggeration: SAM's effects (whether you like them or not) are in no way comparable to the quality of sound provided by Devialet proper.
