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.

    Thanks for the Pono update Mark, it will be interesting to see how the Pono player will compare to the Fiio and Astell & Kearn players when it comes out. Lets’s hope the Ponomusic downloads when they come are the real thing and we don’t end up with more HDTracks shenanigans.

    • Love the TurtleRustler name…LOL! The Pono people will deliver a very nice sounding unit, I’m quite sure of that. But it will be within the constraints of a portable, battery powered device…and that means it will only be so good. The recordings will make all the difference…and sadly, the download catalog will be exactly the same one that HDtracks offers.

    Please check the Sound & Vision magazine site at http://www.soundandvision.com/content/high-res-all-embracingly-defined.
    That is quite confusing! And about the provenance? With the HRA definition from DEG, CEA and RA , everything, but lossless, is HRA. I need to know about the recording source, how was it made. Is it HRA or not? Old recordings made originally in the analog domain are definitely not HRA. I am not saying that they are bad, simply they are not HRA. The audiophile community must be aware of the swamp it is navigating with these loose and inaccurate definitions, which were established to fit all of the interests involved. That is very sad!!!

    • I read the article…thanks for the link. I agree with some points but including analog sources as “high-resolution” is incorrect. CDs can actually provide better fidelity than analog tape.
