Short answer: the March Audio Sointuva AWG if sound quality matters most, the KEF Q Concerto Meta if price matters most. The March Audio Sointuva AWG ranks #5 of 222 bookshelf speakers, rated 4.7/5, at $4,150. The KEF Q Concerto Meta ranks #11, rated 4.6/5, at $999.99, $3,150.01 cheaper.
The case for the KEF Q Concerto Meta: A neutral three way bookshelf speaker that sounds consistent from seat to seat, with smooth treble that many rivals at its price lack. Watch for: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment.
The March Audio Sointuva AWG is the more accurate, deeper-bass option. A Purifi powered bookshelf speaker with extremely flat sound, very low distortion, and unusually deep bass for its size. Its measured preference score, a predictor of how neutral it sounds, is 6.95 against 6.01 for the KEF Q Concerto Meta. Its bass reaches about 40Hz before falling 3dB, against 53Hz for the KEF Q Concerto Meta. The catch: Correct listening axis sits about 7° above the tweeter line, which means shorter stands (around 24”) than typical bookshelf stands are sold at: get the height wrong and the sound scoops out in the mid/high frequencies.
Buy the KEF Q Concerto Meta if the price is the priority over sound quality, or the March Audio Sointuva AWG if sound quality is the priority over the price.
