The optical output is still a bit confusing. One response I got says it
is a pass-through device but is limited to iTunes sampling rates, which
I think are 44.1/16 or 48/16. To me, pass-through implies any rate that
can be run over ethernet, and CoreAudio can do 96/24. I am trying to
acquire more information.

You might get reliable info at the Computer Audiophile forum.

I haven't tried my separate mini-DAC from the Airport--it runs into the
DAC input of my CD player--but I do seem to remember that it won't do
hi-res.

This is not a big deal for me 'cause 99% of my computer files are
redbook.
