Let Roon upsample vs let Lumin T2 do the work

I've reluctantly invested in Roon for my Lumin T2.  I read somewhere to turn off all the processing in the Lumin app and let Roon do all the upsampling.  What's the benefit of that?  I figure my Lumin is built specifically for making the best signal possible. 

Secondly, my Roon core is an Asus ROG desktop computer, is it doing any work?  It's certainly not audiophile grade.

@tuberist thanks for the input.  Why use the computer/Roon instead of the lumin though?
Also, why would one not like the DSD512 presentation?  Isn't that just higher quality or truer to the original?  Isn't it just a higher accuracy basically?

Remember that upsampling is not real DSD. I mean, you can make more data, but it's fake.  It's not actually carrying any more information, but it will tinker with the DAC's mechanics, and change the noise profile.

Then how does one get real DSD?  Download each individual song from some online music service?

DTX, Peter Lie, the head Lumin software engineer, specifically instructs to turn off upsample processing in the Lumin and utilize upsampling through Roon. "Real DSD" is simply a presentation of some music sources although I have yet to find any in my library or browsing. However, if "native DSD" is available the Lumin will process it. BTW, Erik was correct in his upsampling comment. I suggest you check the Roon website, "community" and peruse the Lumin hardware  section....lots of useful info there.
