DAC on a wire

Definitely! We just put up a whole lot of technical information about the guts, if anyone's interested in the architecture / chipset, you might want to check out the new design section.

Well must admit I'm impressed that you've managed to cram all this in such a compact space.
Interesting dac choice

That is tight in there.

Has anyone heard one yet?

Cool devices those CPLDs aren't they, thats what I am using at the moment in my project to produce a differential i2s stream to drive a pair of 1541.

I should read up the link to the USB to i2s conversion links, not something I have looked at yet. Given that I listen to music at work on headphones using the PC as a source maybe its time I did

Yeah, very cool. Actually, I'm not sure how else to do it, at least in that small of a space. I think some DIY types of projects use re-clockers like the CS8420 or similar, but I'm not sure if this is a good solution, since it can add resampling artifacts (?), and it's sort of overkill (price, size, and power consumption) ...

There are some bit-shifting chips out there (shift registers), but you need quite a number of shifts, especially if you want to use one word clock for both channels ... not sure if anyone's had much luck with these, any suggestions? I think the CPLD stands, but I'm wondering what people do for breadboard / prototype types of project ...

I'm wondering what people do for breadboard / prototype types of project ...

At the momewnt I am using one of their Coolrunner II X boards, at $50 its hard to beat. The connections to and from the board are longer that I would hope, but it allows me to experiment with the vhdl. I plan to get a smaller board made wth just the clpd and a tentlabs clock source, enough IO and the JTAG pins, but that for later.

It certainly beats wirewrapping prototypes up (there thats me showing my age :-)).
