Thanks for the info and it does make sense. The Audison would be used to it full potential with the stock headunit. My own headunit doesn't have DSP built in I think. It does have some of the features you listed above.
From the little bit of research I did, the Audison takes sound customisation futher. e.g it has a 31 band eq while my own headunit has 7! Also, it maximises the power from the amp by only feeding the amp the frequencies it has to amplify e.g subwoofer amp gets only fed the subwoofer frequencies you choose. I think it's an elegant solution for people who want to retain their stock headunit and with an aftermarket headunit, gives another level of tweaking that takes the whole system to another level. Been watching a good few videos about it and I am still tempted lol
