I have used Minidsp 4x10HD and three 2x4HD units for many years. I and my friends have never heard any degradation of sound passed thru them, be it analog or digital signal. Measured performance is very good in my eyes too, the imperfections are not audible to me at least. In some casest there has been some hum induced in too long and unshielded RCA cables.
These should be used only with competent measurements of acoustic output. It is too easy to eq. induce clipping in digital or analog domain with wrong settings. With subwoofers, running main speaker signal through minidsp enables to set delay to mains, which I have found very important!
