BV11 if you want the option to turn the TV on its stand or on a wall hinge. I guess that with 55” plus screens and improved viewing angles there is less need to turn the screen so a fixed screen and fixed soundbar will be a good option in many cases, albeit with the risk that everything does not integrate perfectly and multiple remote controls have to be used.
It is still a mystery to me as to why B&O didn't produce a motorised stand or hinged soundbar with PUC control for any TV screen mounted above, but maybe they have also concluded that big screens don't need to be moved (or are impracticable to move in domestic environments.)
