Yes, you'll get an improvement just because of the capability to adjust filters and an EQ. Whether or not you need the high quality output from the headunit too is really outside of my knowledge and a better question for KHA because he's probably listened to both low level and high level headunits.i am also interested in that,can someone provide more info about the topic will i receive with crappy head unit and dsp same effect like high end head unit or even better?
