Should we expect the module will be as small as the current one on your website?

I guess the XMOS chip will already be supported in linux, but will the ALSA driver also be able to play music on 32/384?

Also, the MiniStreamer will not sample 88.2 kHz

Will this implementation be able to sample native 88.2 and 176.4 kHz?

I think to isolate the input from the output.

Leif: using USB bus power does not have to be a limitation if the power is handled properly. The Ayre QB-9 (product of the year, sounds incredible, blah, blah) runs its USB receiver off of the USB bus. And I am using a Wavelength Audio Wavelink USB-SPDIF interface into my B-II which runs off of the bus power, and it sounds amazing. The designer just has to make sure that the USB bus power is appropriately filtered, and regulated, and that some kind of isolation is employed between computer and DAC.
In any case, if you are paranoid about the USB bus power, it is a simple matter to break out the power and ground leads from a USB cable and apply the 5 VDC supply of your choice.

Barrows,
Be careful - you cannot break out the ground from USB - it has to be connected back to the PC for the USB D+ & D- reference. So no galvanic isolation with this method, I'm afraid!

I am well aware of what you are saying. You can still break out the ground and + from the cable and apply whatever supply you want, the ground reference has to stay intact between the computer and USB receiver, and your new supply just references the same ground. I was not suggesting that applying external power provides any (ground) isolation.
In any case, what Russ White/TPA is working on already isolates the computer from the DAC.
