UPDATE: The email arrived that annouced my opportunity to purchase an XDA-1, but I decided not to buy it. I thought I could use the XDA as a pre- and as a source, if I could pipe sound into it from my laptop, but with all the techno garbage I'd have to deal with (audio over USB, iTunes vs FooBAR vs XP64, low hard drive space, driver conflicts, bleh), I'd have to update my OS or buy a new laptop to use as a music server. In the end, if I don't get shot down by tech conflicts, I'll have spent enough to have bought a pre-/CDP, if not in $$$ than certainly in time. I'll DAC the CDP I buy later. Keeping it simple for now.
