I didn't think S/PDIF was capable of 96K, but it would be nice :)
At least I'd be able to get/send 96K in stereo to/from other gear,

??? If you're meaning the Digiface here, wouldn't it also be
8+4+2 == 14, because for every 8 channels at 96K, you need a
*pair* of ADAT i/o; the Digi only has three.

BTW, does the headphone socket work? I seem to remember Paul Davis
saying (when he first wrote the driver) that the only things not
supported (yet) were the headphone/line out socket and the LEDs.
