Schiit Ragnarok 2 (Fully-Loaded) / Digital USB input / No optical


Greetings All, I've just received my new Ragnarok 2 and am excited to set it up later this week. I didn't realize until after I ordered the R2 "fully-loaded" that the internal DAC card requires a USB input. My mistake obviously. This was surprising since almost all of the Schiit DACs are equipped with Toslink/Optical inputs. This currently puts me in a pickle because in addition to playing vinyl, I like to stream lossless files from my Mac to an Airport Express utilizing it's optical output. I haven't found a device / adapter to convert an optical audio signal to a USB, so I may be forced to use an external DAC rendering my purchase of the R2's internal DAC pointless. I may decide to exchange this fully loaded R2 to the "Just an Amp" version, but prefer an all in one box solution since our space is limited. Any thoughts, suggestions etc are most welcome. I have 14 of 15 days left with Schiit's return/exchange policy.

I have no current plans to use the internal phono section because I'm moving the turntable is moving to another system (with ample space for it).  I've been using the internal DAC on my 12 yr old Cambridge Audio's Azur 740. The player includes an optical in which has been super convenient, lovely, transparent,  dynamic etc. this was great for several years, but it developed a 'shearing' sound at certain frequencies, I'm not sure why. If it was related to the Airport Express, it would've been there from the start. The internal Cambridge DAC doesn't make this sound when being fed by the internal CD transport of the unit but streaming from the Airport Express causes it. I've tried a couple other less expensive DACs, but wanted to have an integrated solution since so many components seem to include them these days. But I do like to stay updated, so idea of a stand alone DAC when I'm ready to pull the trigger seems like the best bet. And Schiit offers great upgrades at fair prices.  And I haven't even opened the RAG2 so an exchange will be simple according to Grover at Schiit. 
Will you be using the headphone section? If not, then maybe a vidar, a saga and a bifrost mb?
Yes, I’ll be using Focal Elears and now leaning toward a Bifrost MB for the DAC
