Not yet. I am looking to replace 4 old regular speakers in our workshop and somebody recommended me Sonos, which would also remove problems with rotten cables.
Then I realized that the current Sonos devices come with Alexa or some Google equivalent installed, and you need an account at Sonos and probably at some stream providers to be able to use it. I don't really like that for privacy reasons.
Otherwise having an Amiga solution to control the speakers is really a great option! As far as I know the protocol is proprietary? Good work!
