Default Is there a usb dac out there that does not need a pc

ie the dac itself contains a microcontroller
so that it can be a master. The input would be
a bunch of uncompressed wav files from say,
a usb thumb drive. This external thumb drive
would be slaved to the usb dac - a transportless
digital source with the possibility of minimal
transport induced jitter. A really low jitter clock
can then be used.

Does such a kit or project exist?

Or can the std usb receiver chips from TI etc be
used with some simple glue logic and clock to
accomplish this?

TIA

There are USB DACs that are master of the flow control and so are jitter immune, but they still rely on PC and won't work with the miniature USB drives.
