AppleTV work with USB DAC?

Wow the AppleTV has a fan? I didn't know that. I only saw
it at the Apple store and I really liked the small size and
of course the killer GUI.

I was reading that the AppleTV can be hacked to the point
where you could install a full version of OS X. Somehow
I was figuring if the USB could be enabled for USB harddisks
then the next step would be to copy over Audio Midi Setup,
start it up, and then select the USB port for Audio output.

Gherrera1: I will have to check into that capacitor mod
on the AppleTV. We emailed a year ago when I bought my
Krell 400xi and SACD3. You were considering the AppleTV
or MacMini back then.. I guess you picked the AppleTV..

Has anyone tested various glass Toslink cables to find
out which one sounds best with the AppleTV ?? The 3
Toslink cables mentioned often seem to be:

Van Den Hul Optocoupler
Wireworld Super Nova 5
AudioQuest Optilink-5
