Well, mainly insights concerning DACs I will take from interviews of Ken Ishiwata. Plus, his Japanese colleague, Ryuichi Sawada—because he too speaks authoritatively with reporters. Okay, I've already delayed starting this Thread, which may help readers, for nearly a week since coming across Ken's Polish Q&A and it's English email exchange. Let's just begin : « As you are well aware, DA converters (IC Chips) have changed so much from the time of introduction… Today, you can have very high specification DAC to fulfill all High Resolution Audio formats!! However, do they sound good??? That’s the pertinent question… Personally, I love old non-CMOS DAC like old Philips types (BiMOS) but unfortunately you won’t get those anymore and they are not compatible with new High Resolution Formats… If we can keep everything in Analog, then of course we would stick with Analog but, as you know, that’s not possible… DSD is indeed very popular but not many people know why… In my opinion, it’s related to your first question about DAC IC! Every DAC commercially available nowadays are using delta-sigma conversion for PCM… In other words, you are not getting same DA conversions we used to have with PCM!! Therefore, if you feed DSD signal to such DAC, then you bypass the delta-sigma stage!! Of course it sounds better!!! As you were remarking, Less is More applies here!!! » Yeah, I've left out the questions because I find them overlong, fatiguing. English isn't our first language So you can picture the man, here's a photo of Ken during a presentation (which I had once projected the CS4397 flowchart...) : More relevant quotes for your consideration another time
