I'm using mathaudio Room EQ which is also correcting the phase. I also think that SAM is already correcting the phase by itself, so the phase should be more correct with SAM on than with SAM off. Currently I'm using the REF10 with 2 MC-3 USB in a cascaded configuration, and SAM off is clearly better for imaging and details. I'm still using the Room EQ of course.
But the effect of SAM depends on the speaker, for the Giya I can only use it with the Room-EQ, otherwise it is too much bass, even with SAM at 0%.
