Well, I finally gave up on the Arsy Ne-2 plus. Despite power cycling and/or resetting the device, it's rarely able to receive an audio stream even though it may show up as an option in Apple Music, Spotify, Qobuz, etc. It's only gotten worse as the months go by.
I can rarely connect to the device to see its menu using the IP address to access the setup menu to check the firmware. It's become a hopeless endeavor.
My experience using it has been via wifi. If I'm ever able to situate it where I can try the wired ethernet connection, perhaps that will work better. But for now it's going back in the box.
I have the new Arylic LP20 on the way that will hopefully fulfill the promises of the Arsy. With their current offer, it's the same price the Arsy, more full featured, and comes with its own power supply.
