Only just found this short lived thread - might just add a trailing note, abraxalito has heard it all before, 😀 : I have had, positive, experience with both the R2R and S-D architectures, both can do the job using conventional implementations if sufficient care is taken.
A top notch mid 80's player, Yamaha, using B-B chips has served me well over the years, still runs nicely -- gives me "invisible speakers" if up to speed ... . Yet, my latest "baby", Philips, is pretty rough and ready, uses a classic, cheap S-D chip from Cirrus Logic, and is also capable of delivering very impressive sound. Yes, there are differences: from cold the Yamaha is quite listenable, "smooth" some people might call it, the Philips on start-up has a rather dead, flat, lack of sparkle quality. Both benefit from extended warm-ups, but the Philips benefits particularly from being "thrashed", the circuit has to be exercised heavily over at least an hour or so. An easy method is to feed the DAC with a constant, maximum level, high frequency signal, I use 18kHz -- this brings the treble on song.
So, both technologies are able to produce satisfying results, but standard implementations won't perform adequately if simply treated as push button solutions; they need to be nursed, or tweaked to give of their best ...
