Short answer: the Genelec 8330A. It ranks #7 of 108 powered bookshelf speakers by sound quality, rated 4.5/5, at $2,250; the KEF LS50 Wireless II ranks #19, rated 4.3/5, and costs $2,999.99, so there is not much of a tradeoff to weigh.
The case for the KEF LS50 Wireless II: An all in one wireless stereo system with accurate, consistent sound, HDMI eARC and built in streaming. It keeps a wired aux input, which the Genelec 8330A lacks. Watch for: The 3.0dB response span is good but not reference-leading, and dispersion still varies with frequency.
Why pick the Genelec 8330A: An accurate compact studio monitor with room calibration support and deeper bass than its smaller sibling. Watch for: The listening-window response has more local variation than the Genelec 8030C or KH80 in the selected measurements, so DSP capability should not be mistaken for superior native neutrality.
Buy the Genelec 8330A. It is rated higher for sound quality than the KEF LS50 Wireless II and costs less, so only choose the other one for a particular feature it does better.
