Does the DSP in JBL M2/Crown amp diminish the sound quality?

The Crown iTech amp that comes with M2 has BSS DSP for equalization. While this may give the listener option to change sound quality, I am thinking that the sound quality may diminish because it is taking your analog preamp signal to digital, to EQ and back to analog. This is kind of like taking a digital sound through a DAC and back to a digital sound. What do you think?
