The Aurender Conductor is a solid app that is easy to use and rock solid. If someone is having issues with connectivity it is probably their network, not the Aurrender.
OP… you want to purchase an N level streamer only product. Then you can choose the DAC separately. This gives you great flexibility.
I own both an N100 and W20SE streamer. They are world class and cost effective. I have owned and auditioned others. This is the brand to get. My systems are under my UserID.
