Not today. And there are even a few academics on-list with ties to
electrical engineering departments, so that the design cost of a
converter package suitable for audio research work might be almost
negligible, too. Thrown into the free and open domain, a well-thought
out package like that could easily become a landmark piece in open
hardware, it'd make all of our lives much easier and less costly in the
still-experimental high multichannel space, and you might even be able
to get a couple of PhD's/EE's out of it and/or its applications. Spin
out a couple of startups in a startup-poor economy, and what not. What's
not to like there? ;)
I am ignorant of the economics, but perhaps it is worth considering an
FPGA-based implementation:
"An FPGA-based Re-configurable 24-bit 96kHz Sigma-Delta Audio DAC"
Ray C.C. Cheung et al.

In theory the USB transceiver and the DAC(s) could all be baked onto a
single FPGA.
