Default USB to I2S?

I was thinking about building a Hag USB.... I could use it's audio out for awhile, and then I could switch over to an external DAC (Peter's premium probably). Well Peter's DAC accepts I2S which is not confentational with Jitter right?

Here is a double check

Does this unit run off of I2S?

No. It only outputs the standard S/PDIF format. No machine out there has I2S outputs. Or inputs, for that matter.





My understanding is this is the only way to go for getting a digital signal out of USB with out jitter issues...

That is a popular myth floating around the DIY forums.

The only chips I know of that output i2s from usb are the pcm2706 and pcm2707. They are pretty simple to use: here are a few projects I've done.

As for the jitter myth, there has been some good discussion over at diyhifi.org

USB-I2S with PMC2707:

Works like a charm on my older TDA1543 DAC, and you can use it on its own, although I wasn't very impressed with the built-in A-D.
