Short answer: the Ascend Acoustics Sierra-LX. It ranks #37 of 222 bookshelf speakers by sound quality, rated 4.3/5, at $1,598. The KEF Q3 Meta ranks #156, rated 3.4/5, at $764.97, $833.03 cheaper, a saving that is not big enough to make up the sound-quality gap.
Why pick the KEF Q3 Meta: Coaxial bookshelf speakers with very wide dispersion, punchy kick drums and bass tuning that works close to a wall. The catch: Not well suited to high-output use: compression and strain in the 1-2kHz region emerge above about 90dB at 10 feet, so a high-output home theater setup isn’t the best application.
The Ascend Acoustics Sierra-LX is the more accurate choice. A compact bookshelf speaker with very neutral, flat sound, a wide soundstage, and surprisingly deep bass in a bamboo cabinet. Its measured preference score, a predictor of how neutral it sounds, is 6.63 against 4.66 for the KEF Q3 Meta. Watch for: Very low sensitivity at about 81dB, so it needs a genuinely powerful amplifier to reach normal listening levels.
Buy the Ascend Acoustics Sierra-LX. It is rated higher for sound quality, and the $833.03 you would save on the KEF Q3 Meta does not close the gap.
