I recently tried this setup myself for my home.
Over the years I have not been very happy about Autonomics reliability at my client's home so I wanted to see how this would work as an alternative.
?
I use it the same way you described. I only use it as a 4 zone media player.
?
I have not used it for very long, but so far its been reliable.
I have only tried Tidal , Podcasts and TuneIn.
?
I have not used it for weeks and before writing this and tested it out and its still going.
?
I think the price point / features vs Autonomics is worth looking into.
