About Avantrec

Avantrec Ltd is a startup company based in Bristol in the UK. SonoPlus is one of our development projects.


We love our Sonos systems, and the idea for SonoPlus emerged from some home projects to make our Sonos experience even better. The results were so good that we decided to experiment with productising and simplifying them, to make them available to everyone without needing any technical know-how.

If you know your way around a Raspberry Pi, we offer a popular Docker packaged version of AirConnect optimised for Sonos speakers:
