currently I use the built-in soundcard in my Numark Mixtrack Pro, but I was wondering if there would be a noticeable difference in sound quality if I used an Audio2? (the Native Instruments one).

Now I have a gazillion midi controllers and am starting to get more into it, I want to make sure I'm not putting out sub-par sound, for the sake of $100 (which, compared to say, even just my midifighter pro, is not that much to spend)
