I have been using an Auralic Aries for quite some time and continue to use the Lightning DS app. I have tried other apps as well including Linn Kinsky which isn't bad at all and Roon which was just too much of a bother as I didn't like how it catalogued my music library.
Auralic Lightning DS App
Would any current users please comment on their experience? I'm considering a Vega G1 Streamer-Dac and the app ease of use is very important to me. I don't own a Lumin device and their app looks fairly intuitive and featured.
