Hey it works for the dogs! Regardless of how audible* I still find the theory and application interesting. I did email Ed Meitner's company asking why it was important that "DSD-Wide" kept the same sampling rate, but no answer so far. But again, all these things pale compared to the skill of the recording and mastering etc. And also everything ends up PCM if you're doing any room EQ (I supposed time alignment can be done in a 1-bit domain, and bass management analog). In the end if one team loves their DSD workflow and another their PCM, and another is still on analog tape, I could care less as long as the results sound great).
*even if most people can't hear a difference, maybe some on their particular setup can. I doubt I'll ever hear a "pure" comparison, and I run room correction so it matters not to me. I love SACD for some of the great titles, but detest it for the difficulty in ripping. I should probably buy one of those old PlayStation or whatever...
