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 134 bookshelf speakers, rated 4.7/5, at $4,150. The KEF Q Concerto Meta ranks #11, rated 4.6/5, at $1,399.99, $2,750.01 cheaper.
The case for the KEF Q Concerto Meta: Really good in-room neutrality with consistent horizontal directivity from seat to seat. Watch for: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment.
Why pick the March Audio Sointuva AWG: Purifi drivers deliver exceptionally low midrange distortion (the reviewer calls them “world class”) paired with bass extension unusually deep for a bookshelf (F3 40Hz, F10 30Hz), reaching down to about 30Hz in-room with some boundary reinforcement. The tradeoff: 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.

KEF Q Concerto Meta: $1,399.99 per pair Amazon Crutchfield eBay
Pros: Really good in-room neutrality with consistent horizontal directivity from seat to seat. Directivity holds remarkably steady from lower treble into upper treble, where many similarly-priced speakers narrow sharply as frequency rises: one of the reviewer’s top 10 picks under $1,500. Measured bass extension of 53Hz (-3dB), with a measured sensitivity of 84.2dB.
Cons: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment. Needs to be pointed closer to on-axis rather than heavily toed out: combined with its rolled-off, shelved-down top end, too much toe-out makes it sound noticeably dark.

March Audio Sointuva AWG: $4150 per pair March Audio eBay
Older model: the March Audio Sointuva (ranked lower, rated 4.6/5).
Pros: Purifi drivers deliver exceptionally low midrange distortion (the reviewer calls them “world class”) paired with bass extension unusually deep for a bookshelf (F3 40Hz, F10 30Hz), reaching down to about 30Hz in-room with some boundary reinforcement. Sensitivity tolerance band measured extremely tight at 1.6-1.73dB, indicating excellent build consistency. Estimated in-room response is exceptionally smooth and neutral: one of the flattest the reviewer has measured, with none of the usual coloration descriptors (bright, boomy, nasal, shouty) needed to describe it. Distortion stays so low even at loud volumes that there’s no audible warning cue before you’re playing dangerously loud: a backhanded compliment to how clean it sounds. At $4150/pair, ranked among the reviewer’s top three bookshelf speakers in that price range. Measured bass extension of 40Hz (-3dB), with a measured sensitivity of 82.4dB.
Cons: 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. Moderate-low sensitivity (~82dB) is roughly 3dB below a typical bookshelf speaker, meaning close to double the amplifier power is needed for the same output; low impedance also calls for a 4-ohm capable amp. Horizontal radiation holds a wide ±60° only up to about 3kHz before narrowing: tighter top-end dispersion than the reviewer’s preferred ±60-70° through the treble, and the reason he left the previous generation off his all-time top-five list. Multitone distortion rises above the reviewer’s personal 3% threshold in the 1-2kHz region, though it wasn’t audible in his listening. Not intended to be crossed over with a subwoofer at 80Hz: designed to play full-range down to 40-50Hz, so pairing it with a sub and cutting it off early wastes its bass capability. Best positioned about 3 feet from the rear wall, requiring more floor space than many bookshelf speakers.
