Which makes the biggest difference?


In your opinion which component make the biggest SQ difference in the chain of a digital playback system: the amplifier, the preamp or a DAC?
Or, is it impossible to determine?

I’m just referring to digital playback here.
I forgot to mention source, such as streaming or spinner.
DAC. Just remove the preamp. If it's better SQ it's a crappy preamp not worth consideration.
Well, yeah, the traditional analog electronic components truly get your system up 'n zooming. But when it comes to collecting and translating those digits into stuff the old school gear can recognize, for me the DAC brings to bear the biggest difference. Heck, my DAC even makes the YouTubes that come off my laptop sound pretty good.
