What it says in the title: Could someone explain to me, in a simple-enough way, the real difference between the two, and exactly why everybody seems to think that R-2R/Multibit is so much "better?" And if delta-sigma does in fact suck so very much, why the heck are all the major manufacturers leanign towards using it in almost all their DAC chips these days? Finally: Are there any CHEAP options out there for DAC's (with USB input) which use R-2R instead of delta-sigma? Like, below 300 or 400 dollars? Edit: I changed the title of the thread, at @x RELIC x's suggestion, to better reflect what I was actually trying to ask.
