Short answer: the KEF LS50 Meta. It ranks #4 of 179 bookshelf speakers by sound quality, rated 4.5/5, at $1,599.99. The Avantone Pro CLA-10 ranks #124, rated 2.8/5, at $1,398, $201.99 cheaper, a saving that is not big enough to make up the sound-quality gap.
The KEF LS50 Meta is the more accurate, deeper-bass choice. An iconic compact KEF speaker with highly accurate sound, pinpoint imaging and a coaxial driver that keeps tone even across the room. Its measured preference score, a predictor of how neutral it sounds, is 5.74 against 2.23 for the Avantone Pro CLA-10. Its bass reaches about 68Hz before falling 3dB, against 159.7Hz for the Avantone Pro CLA-10. Watch for: F3 of 67Hz and F10 of 42Hz mean it doesn’t get much below 50Hz in-room; a subwoofer is recommended for real bass.
Why pick the Avantone Pro CLA-10: A rugged passive sealed studio monitor that recreates a classic nearfield mix-check speaker for studio workflows. Watch for: The local Spinorama score is only 2.23 raw and 5.87 with a subwoofer, with 101Hz extension: objectively bass-light and far from neutral.
Buy the KEF LS50 Meta. It is rated higher for sound quality, and the $201.99 you would save on the Avantone Pro CLA-10 does not close the gap.
