Best way to send digital to DAC

I have a. Synology NAS and there is some software on it but it didn’t seem to perform the “rendering “ function.  Since I already owned Bluesound and was interested in controlling my NAS with that I didn’t explore it much further.  A think the Node 2 or 2i is a great way to control the NAS, sounds very good, and offers every music service from Internet Radio and every streaming service.  I am listening to the new Andries Nelsons Boston Symphony recording of Shostakovich Seventh Symphony via on Qobuz with the Node2 and it’s highly satisfying.
btw, if you use a renderer such as Bluesound, you don’t need to connect the Synology to the DAC.

I have a Synology NAS and for years and years used Logitech Media Server (beta) to stream music to Raspberry PI DACs, SqueezeBox DACs, and AirPlay wireless speakers.  Using LMS plugins you can stream Tidal, Qobuz, Sirus, Pandora, AirPlay, etc, and play DSD, FLAC. iTunes, MP3, and other files. 

I now use Roon instead of LMS.  If you care about MQA, the Node2 is probably a good choice.  I use a Mytek Liberty DAC and an Innous Zenith MK2 for streaming/rendering everything.  Before Roon, I tried the BluOS app but found it too limiting because, unlike Roon or LMS, you can't consolidate all music sources into one interface.

Thank you.

I'm looking at the Aurender N100H because I heard the USB output is noticeably cleaner and more airy and the interface is good without having to pay extra for interface software like Roon.  Does that sound like I'm headed the best way?
