Dialog replacement for device independent music

[mvrlondon]

Does anyone know if I can stream to the Phantoms with https://volumio.org?

Yes, that will work. 

You'll need a optical output HAT for the raspberry Pi - https://www.hifiberry.com/shop/boards/hi...d-version/

Then plug the output of the HAT into the optical input of one of the Phantoms.

Volume control will still be via the Devialet app
