Short answer: the Marshall Kilburn II. It ranks #39 of 82 large speakers by sound quality, rated 3.8/5, at $279; the B&O Beosound Level ranks #65, rated 2.8/5, and costs $2,250, so there is little reason to consider the other one.
What the Marshall Kilburn II does well: 20W Class D amp + dual 8W tweeters. Watch for: Boosted upper bass, not very detailed, not as deep bass as competitors, upper mids peak.
The case for the B&O Beosound Level: Premium Scandinavian design with elegant domestic sculpture aesthetic. Watch for: Not very deep bass, peaks in midrange.
Buy the Marshall Kilburn II. It is rated higher for sound quality than the B&O Beosound Level and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
