Roon - streaming only...where'd you get your NAS?

I use a Synology NAS and converted my old INTEL NUC to a Roon Rock.  I didn't shell out the 499, but decided to do the 120 per year to give it a full test.  I think it is a great app and provides liner notes and artist info that otherwise I would never see when streaming.  I do wish they developed an APP for Apple TV to stream the current song's info. 

For endpoints I use my Sonos connects and I have one ultra Rendu I bought to experiment with Hi-REZ files from Quboz and Hi-rez downloads. I am not sure the Hi-Rez files by themselves are worth it, but found to be very recording dependent. Quboz didn't have enough of the titles I wanted and too few Hi-Rez.  I am using tidal, but will eventually cease once I fill in my library with a few genres I neglected for many years - mainly early punk and progressive rock.

I am curious on the Innous - if that is tremendous improvement over NAS to DAC, or NAS, to Ultra Rendu to DAC.  I am guessing marginal, but I am nonetheless curious.  Just a lot of money to drop.

One thing to note I would not post your looking for free music - coping someone else's music etc.  as that goes against recording industry law. Pirating. Keep that stuff to your self

Reviving this with new question.  

I have the Anthem STR Integrated amp and Bluesound Node 2i.  Am i correct to say, if I want to use Roon, I have to have an endpoint?  Or a computer nearby always on?

I still have no NAS so it would only be for streaming.

I cannot figure out any benefit from Roon without a NAS.  BluOS is awesome, would Roon really be better?

Again - NON NAS user here..
