Very nice review! You did lots of work on this. A couple of things I know from use of the DX120, the back has a screen saver on it of plastic and that is why you see scratches. Under that is glass so nothing is really scratched except the screen saver. I use 2 400gb cards and thought the scanning was actually very good. Better than any of my other daps for speed. Lots of very good info here!
