Short answer: the Genelec G Two. It ranks #21 of 108 powered bookshelf speakers by sound quality, rated 4.3/5, at $1,390. The KEF LSX II LT ranks #36, rated 4.0/5, at $749.99, $640.01 cheaper, a saving that is not big enough to make up the sound-quality gap.
Why pick the Genelec G Two: A compact home speaker built from a studio monitor, with natural, uncolored sound and an RCA input for consumer gear. It has an adjustable EQ, which the KEF LSX II LT lacks. The tradeoff: Bass reaches only about 54Hz (-3dB) and fades by about 48Hz (-10dB), so it needs a subwoofer for full-range music or movies.
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. Watch for: The 3.4dB midrange response span and treble-region dips keep it below more neutral monitors.
Buy the Genelec G Two. It is rated higher for sound quality, and the $640.01 saving on the KEF LSX II LT is not enough to make up the difference.

- Close enough not to matter: bass extension (48 Hz vs 46 Hz, 10 dB down).
