I have exactly the same problem with choosing between Sonos Move and B&O Beolit 20.
What about hifi codecs. Will the old versions of the codecs in Beolit 20 significantly affect the quality of the sound ? It seems that Sonos Move is better in this aspect, unfortunately it is also only a mono speaker and Beolit 20 plays stereo sound.
Which one should I choose considering sound quality only ???
Or maybe there is 3 better option?
