C-B, perhaps you have access to better pricing but I see the Yamaha equivalents to play:1’s @ £120-150 vs £150 for the sonos so doesn’t seem to be a ‘huge cost difference to me, the Yamaha version of the connect is also £150 so not a massive saving once your connect is sold, though for transparency I do already have Sonos in two homes so could be biased.
Interested to hear which way you go.
