I'm going to go out on a limb and suggest that for $2k, the best thing out there is likely to be a musicserver rather than a CDP. I am still figuring out which way to go, but for $2k, I would be leaning towards a Mac mini + a Buffalo DAC from twistedpearaudio.com. $2k would get you a dedicated MacMini, lots of hard drive space, a Buffalo DAC and the trimmings, and a cable between the two. Depending if you got your MacMini used, how much HDD space you got, the cost of your USB cable, and what trimmings you put on the DAC, you could probably also get an iPod Touch to use as a remote control for your system, in which case you'd have the coolest and upgradeable $2k CDP out there... The other way to go might be to build a cMP music server - recipes are available on the PC Audio forum on AudioAsylum. When I did the math, it came in under $2k. Both look like excellent solutions.
Disclosure: I have used Macs for several years, and have an iPod Touch, which I think is great. I also have a CDP in a second system which I bought for just under $2k several years ago.
