Curious why you would duplicate the Roon endpoint functionality of the shd studio with the auralic Aries?
@win You do have a keen eye
My stereo setup also doubles up as my tv sound system - I use apple tv to stream content and use airplay to send the audio to my stereo setup. In my experience, the airplay on the SHD studio isn't very stable. It works at times and doesn't work most of the times. So I added Auralic Aries to the setup - it works like a charm for both airplay and roon.
