Short answer: the B&O Beosound A1. It ranks #9 of 134 medium speakers at $200; the KEF Muo gen2 ranks #72 and costs $249.99, so there is not much of a tradeoff to weigh.
On the B&O Beosound A1 side: Deeper bass than the A1 2nd gen. Set against that: Not stereo.
The case for the KEF Muo gen2: KEF seemed to have fixed the rolled off treble and overall balance. The tradeoff: Lacking deeper bass.
One note: the B&O Beosound A1 is discontinued, but it still ranks #9 of 134 medium speakers, ahead of most of what is still sold new, so it is worth considering used.
Buy the B&O Beosound A1 if the ranking matters more than the price. Buy the KEF Muo gen2 if the price matters more than the ranking.
