I asked a similar question several months back when deciding whether to go all-in on Chord and add a Blu2 or not. (I did.) My question was, to paraphrase -- a pure DSD recording... with pure DSD processing... how can anyone argue that going to PCM and then to DAC will be better than a good DSD DAC based on the merits of PCM over DSD? I believe there were some replies around the issue, but I would have to say the answer is -- if you are in pure DSD land, then that is a tough argument to make. However, other than specialty productions targeted at the SACD market, most other commercial music has been processed in PCM on a DAW already, so going back to DSD would have the detriments you quoted. In my research, I could only identify two DAWs that process in pure DSD -- Sony (father of DSD) Sonoma and Merging Pyramix. Every other DAW I research may have DSD capability but actually convert into PCM. So I concluded that unless I go out of my way to find a demo SACD or demo DSD file, none of the music I actually listen to avoids an existence in the PCM world.... Thus, a system optimized for PCM works just fine for me!
