No answer here, ok, I answer by myself:
I have both now - the Devialet Soundbox (DS) and the Sonos Beam (SB).
All over I prefer the DS. It has a much deeper bass and the voice reproduction is a litte bit clearer. The special DS/Sky Sound is a very nice add-on, if you are a Sky client. Only if the SB is supplemented with two Sonos One, the "surround" feeling is better with the SB/Sonos One.
The DS is very good deal, if you can get the DS as a Sky client für 299 €.
