  1. iPod, Pure i20 and jitter

    (I’m still just getting up to speed on computer audio, so forgive me if my terminology is a bit shaky.) For reasons I’ll explain below (if you’re interested), I’m thinking of using an iPod Classic with an iPod dock, probably a Pure i20. I’d like to run the digital output of the Pure i20 into a separate DAC (probably a Micromega MyDac, Musical Fidelity V-Dac II or Arcam rDac). But I’m wondering what this means in terms of jitter or other potential pitfalls I may not be aware of. As I understand it, an asynchronous DAC takes over the timing function from a computer when the two are connected via USB. But I don’t understand whether this is a concern running an iPod into a Pure i20 and then into a separate DAC (or for that matter, the implications of jitter using the Pure i20 by itself, without a separate DAC). Is the connection between the iPod and the dock a USB connection? Do I even need to worry about this stuff? Most of my music is Apple Lossless redbook, but I’d also like to try the occasional high-res download in the future. So my questions are, will using an asynchronous DAC fix any jitter concerns, and are there any other considerations I need to take into account with a setup like this. Sorry to be so long-winded. And thanks if you’ve stuck with me. -Bob OPTIONAL BACKGROUND INFO: I’d rather use my MacBook Pro running to a DAC and then on to the Arcam integrated amp of my main audio system. But my MacBook Pro is waaaay far away from my audio system, meaning really long runs of a USB cable from the Mac to the DAC and then long interconnects from the DAC to the Arcam. I'd also have to hook it all up every time I want to listen. It would also be a PITA to move the Mac every time I want to listen to music. So that’s why I’m thinking of the iPod dock system.
