Short answer: the Genelec 8330A. It ranks #7 of 108 powered bookshelf speakers by sound quality (rated 4.5/5) at $2,250 and is still sold new; the Devialet Phantom II 98 dB ranks #11 (rated 4.4/5) and is discontinued, so it is only an option used. The Devialet Phantom II 98 dB’s replacement, the Devialet Phantom Ultimate 98dB, is rated 4.4/5 at $3,998.
The Devialet Phantom II 98 dB is the more accurate, deeper-bass option. A compact wireless streaming speaker with startlingly deep bass for its size and an even, well balanced sound. Its measured preference score, a predictor of how neutral it sounds, is 6.87 against 5.54 for the Genelec 8330A. Its bass reaches about 30Hz before falling 3dB, against 55.7Hz for the Genelec 8330A. Watch for: Small-enclosure bass extension at the measurement level does not guarantee the same response at high volume.
Why pick the Genelec 8330A: An accurate compact studio monitor with room calibration support and deeper bass than its smaller sibling. The tradeoff: 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, and the Devialet Phantom II 98 dB is discontinued, so it is only available used.
