I had the exact same question for the exact same reason - wanted a Bifrost and Schiit being USB Nazi's.
The Juli@ isn't bad @$130 shipped and the drivers/software look great from pictures - I'm out of the country so can't install one yet.
I remember seeing somewhere that optical measured much higher jitter than coax. Otherwise, you won't hear a difference with 192kHz, but I wanted it, too, for the simple fact I've downloaded files that were only available in that resolution :)
