Short answer: the B&O Beoplay A2 active for better sound quality, the Marshall Kilburn II for the lower price. The B&O Beoplay A2 active ranks #16 of 77 large speakers at $400. The Marshall Kilburn II ranks #36 at $257.97, $142.03 cheaper.

What the B&O Beoplay A2 active offers: B&O’s True360 sound from both sides. Set against that: Not stereo.
The case for the Marshall Kilburn II: 20W Class D amp + dual 8W tweeters. The catch: Boosted upper bass, not very detailed, not as deep bass as competitors, upper mids peak.
One note: the B&O Beoplay A2 active is discontinued, but it still ranks #16 of 77 large speakers by sound quality, ahead of most of what is still sold new, so it is worth considering used.
Buy the B&O Beoplay A2 active if sound quality is the priority over the price, or the Marshall Kilburn II if the price is the priority over sound quality.
