Extremely well said guys. The concept of the pre-pre amp and the importance of the analog stage.. also what about R2R dacs... the chip does it all argument falls apart there.
My experience is that dacs can make a big difference sonically and I could easily hear differences in many of the dacs I had. Right now my ANK 4.1x has a very distinct sound relative to my denafrips terminator or PS DS mk1.
Its weird to me how you could make such a big mistake by simplifying everything to 'a chip is a chip'. When I posted about this on head-fi surprisingly many people were actually agreeing with the guy in the video and it left me scratching my head.
