AppleTV work with USB DAC?

Have a look at the above link Tom. They are the fellas over in Hong Kong who did the usb filter mod on the ATV. They also do comparisons using a DAC1 and Krell 400xi.

Tom, I've been extremely happy with a Van Den Hul Optocoupler connecting Airport Express to my DAC. The only thing that bugs me is having to use a cheap plastic mini-adaptor to make it work. The one I have came from Parts Express. The connection doesn't feel as solid as I want it to. If anyone can recommend a better solution, please let me know! I wish Apple would just add a standalone Toslink, but I doubt that will happen.

I'm 6ft away from a Mac Mini now and I hear nothing. How quiet do you need it?
