Mark Waldrep, aka Dr. AIX, has been producing and engineering music for over 40 years. He learned electronics as a teenager from his HAM radio father while learning to play the guitar. Mark received the first doctorate in music composition from UCLA in 1986 for a "binaural" electronic music composition. Other advanced degrees include an MS in computer science, an MFA/MA in music, BM in music and a BA in art. As an engineer and producer, Mark has worked on projects for the Rolling Stones, 311, Tool, KISS, Blink 182, Blues Traveler, Britney Spears, the San Francisco Symphony, The Dover Quartet, Willie Nelson, Paul Williams, The Allman Brothers, Bad Company and many more.

    . . . until you *hear* DSD on a DSD-capable DAC that does not convert to PCM somewhere along the way. Then you understand why people want DSD and will pay a premium for it.

      John, thanks for the comment. I have heard lot of DSD and can’t say that I agree it sounds better than high-resolution PCM. I would ask though knowing that virtually everything you’ve ever heard in DSD went through a PCM or analog tape stage…doesn’t that say something about the better sound of DSD?

    “I have a hard time understanding why the world needs or wants DSD when practically every production (85% of them) involves analog tape or PCM encoding. Doesn’t it just add to the confusion around computer audio and delivery formats?”

    Of course it does! And I disagree with “John” above who tries to imply that audiophiles are lined up to abandon PCM and rush to DSD. It seems to me that many DSD supporters (numerically not that many actually) are old vinyl guys who were digital nay-sayers when CD’s first came out, and now DSD/SACD gives them a way of saving face in the current digital age. This is not to say that many great SACD’s haven’t been produced, but this continuing DSD fetish seems so redundant and useless.
