My experience with Bluesound vault2 for near 2 years.
I consider it to be a stunning bargain at $1000 and the Node2 at $500 should give the same streaming experience. If you do not need the CD ripper go with the Node2.
Imho the sq via its own dac through analog outs is considerably worse than as via spdif to my Brooklyn DAC. It’s not even close in my system.
Others report different experiences but just my notes here.
The Bluesound app on android is a joy to use and handles tidal, Quboz,Deezer, Spotify and many more direct in its own interface. I have found it to be much better than say Tidal own android app.
And Bluesound are constantly updating both the app and the players, all done seamlessly over the net.
I do not think you could go far wrong with a node2 at $500.
