I received the Arcam and it sounds great. I run it into my Dac. You install the PlayFi app on an IOS device to access music services, Tidal, Spotify etc. as well as internet radio and a NAS. I'm using wifi but it can also be connected to an ethernet cable.
I looked at the Auralic G1 and I fail to see what it offers over the Arcam. Thoughts?
