Lumin X1 with Innuous Zenith Mk3 Question

I have a Innuous Zenith Mk3 server and am considering a DAC upgrade.  I am wondering if I buy a Lumin X1, will I even need the Innuous anymore?  I have a NAS drive wired directly to my Innuous so onboard storage is not a high priority.  I know the Lumin offers streaming capabilities.  I do use ROON for streaming and run the ROON core on my Innuous server, so if I get rid of that how would be the best way to run ROON?  

By the way, I am only CONSIDERING the Lumin X1 as the DAC upgrade.  I am also considering other DACs in its price range.  The dCS Bartok is another I am considering.  While this post is not explicitly asking for high end DAC recommendations, I am also open to your suggestions.  

Thanks for your help.  I'm not extremely savvy with digital gear so I appreciate your suggestions.
