what is the missing link?

I would recommend ROON, too as it will manage all your music files in your Synology well and allow you to use an iPad as a remote. I'm running RoonServer on a Intel NUC (Win10) and AIR-ed to my Le200. And, I can play all music type from 16/44.1 to 24/192 and DSD64.

Today I got a trial period of ROON and installed it on my computer ( Win 10) and runs AIR to my 400 and my tablet as remote, works flawless. And the sound is to my ears right now better than my Aries. This might be the start of a new streaming solution.

Glad to hear another user having AIR working flawlessly. Add JPlay + Fidelizer to your setup, and the SQ is even better. And, if you use Spotify Premium, you can even remote control it using your tablet or smartphone (via Spotify Connect).

I am thinking of geting a NUK and run ROON on that like you are. Audiophile optimizer is beta testing a program for Win 10 that is sounding very promising so that might be some for us that dont want to use MS Server 2012. I have Tidal and that works very good on ROON.
