Short answer: the KEF LSX II LT. It ranks #36 of 108 powered bookshelf speakers by sound quality, rated 4.0/5, at $749.99. The Edifier M90 ranks #24, rated 3.3/5, at $369.99, $380 cheaper, not enough of a saving to outweigh the sound-quality gap.
The case for the Edifier M90: A desktop pair with HDMI eARC, optical, USB-C and LDAC Bluetooth, plus a remote and subwoofer output for TV or PC. It keeps a wired aux input, which the KEF LSX II LT lacks. It has an adjustable EQ, which the KEF LSX II LT lacks. The tradeoff: No independent anechoic or Spinorama measurements have been published yet, so its tonal balance and directivity can’t be compared with ranked speakers.
Why pick the KEF LSX II LT: Compact wireless speakers with HDMI and optical inputs, made for a TV or desk, with sound that stays even across a sofa. The catch: The 3.4dB midrange response span and treble-region dips keep it below more neutral monitors.
Buy the KEF LSX II LT. It is rated higher for sound quality, and saving $380 with the Edifier M90 does not make up for the sound-quality gap.
Worth knowing: the Edifier M90 has not been measured yet. Its rating is estimated from related models, with a likely range of 3.1 to 3.5, so treat this verdict as provisional.
