DAC for iPad and USB?

[kiteohoi]

I am making a tripath 25w amp, and I have an idea I could make a DAC that I can connect my iPad to (via a camera connection?) or a computer via usb.

Does anyone know if there is an ebay component I can use? I am basically looking for an already assembled board I can build a box around, and add power supply if needed.

Not quite what you want but...

For about a hundred bucks (USD) a company called "Pure" makes a nice iPad/iPod dock that has a pretty good DAC in it. Have a look at this :

i-20 - Hi-Fi Quality Dock for iPod/iPhone.

Best,
