Spotify Connect Plugin + High Resolution

The Spotify Connect plugin works well, but is limited to 320, which is good for MP3. Will the plugin be updated for high-resolution files?

A subscription-based approach, like that of Qobuz and Tidal Connect, would be appropriate also. Is this being developed?

Spotify did indeed recently talk about Spotify Hi-Fi, but there aren’t concrete details yet.

For more discussions from the Volumio side, have a look at Will the new Spotify HiFi be supported? and I really hope Spotify Hifi won't be part of the paid Volumio subscription
