I just did new tests on SAM% impact, using ear perception and monitoring the membrane movement of the speakers. I used pure frequencies between 10 Hz and 300 Hz.
The results were some expected, as well as some unexpected.
The expected result: the impact of SAM% decreases with increasing frequency. I think it was expected to be so, as the value of the correction needed and introduced by SAM decreases with frequency.
Unexpected results:

Unexpected results:
- SAM% impact is major in the range 10 Hz - 30 Hz and very small outside this range (30 Hz - 300 Hz).
- Even if SAM% is set to "0", an audible bass boost is made. As stated by Devialet, this setting should only effect phase correction and speaker protection, and not bass boost.
