That's NOT the USB version. The site lists only the standard studio version with S/PDIF and the optical connections, plus the unavailable FW version.
There is a LOT of confusion over what is now available, and what will be in the future in the entire Mini-DAC line. The last thing I was told by someone at Apogee in late July was that there would be no more USB versions produced.
Big, big problems otherwise, too.....Apogee ran out of a chip required to make Mini-DACs for a while and found that to have more fabbed would take at least 6 months. The claim was that they were scouring the world for what might remain in other stocks, and promised to have then in the hands of vendors by mid-July.......then by the end of August......and now it seems no vendors have them at all.
I have not received consistent info on this one, from either Apogee directly or from vendors--at first, it was supposed to affect only the FW versions, then all Mini-DAC's, and finally someone told me that it affected all Mini series components. Two of the vendors told me that, based on what their Apogee rep had told them, they wouldn't be surprised if they never, ever got another Mini series unit of any sort from Apogee. Seriously, that is what I was told, but it might have been a sales pitch to get me to buy something on hand.
It is probably worth a call into Apogee to get the real story at this point--personally, I didn't want to buy a piece that couldn't be repaired due to lack of a critical part. Seems to me if they can't make any new ones, that scenario might be possible--or a repair might take eons to complete.
