Room correction with Phantom

[Snoopy8]

What is best way to go with my system if i want room correction. I have now 2x Phantom Golds with Dialog, Source Mac Mini (late2014 sp/dif out upto 24/192) miniplug-toslink to dialog and i use spark/tidal hifi. I have dirac room calibration software with umik-1 mic and dirac au and vst beta-plug ins. Phantoms are connected with plc, dialog and mac are same network with lan. Should i use Audirvana or is there better options in my case? 

My own tests suggest that you should use Upnp to the Dialog rather than optical in.  But since you are using optical, the ideal situation using miniDSP:
  Mac Mini -> optical/coax RCA -> miniDSP DDRC-22D -> optical -> Dialog/Phantom

I think you have a miniDSP running Dirac with analog output?  If that is the case, then your will need to convert the miniDSP analogue output to optical (yuk!!!).

I am not familiar with Audirvana.  Does it have Upnp and room correction?  If so, you can do room correction in Audirvana and cast to the Phantoms using Upnp.
