To get best sound quality, roon or lumion app?

To get best sound quality which way is the best to go, us the Lumin app in my Lumin T2 or use Roon to make dsd512 -> T2?
spinaker01 -> are you using upsampling to dsd or anything?
rossb -> do you use upsampling to dsd?
I have the Lumin U1 and detect no difference in the sound between the Lumin and a Roon apps.  You can tweak Roon to change equalization and DSP settings, but I leave Roon settings alone.
