Short answer: the Genelec 8320A. It ranks #8 of 67 powered bookshelf speakers by sound quality, rated 4.5/5, at $1,700; the Devialet Phantom II 98 dB ranks #9, rated 4.4/5, and costs $2,998, which makes this an easy call rather than a real tradeoff.
The case for the Genelec 8320A: A measured 1.6dB span from 300Hz to 5kHz and preference scores of 5.52 standalone and 8.04 with an ideal subwoofer support accurate close-range monitoring. The tradeoff: The -3dB point is about 67Hz, making a subwoofer important for lower bass and giving the larger 8330A a practical advantage without one.
What the Devialet Phantom II 98 dB does well: The manufacturer-supplied measurement shows unusually deep bass for the enclosure size: -3dB at 30Hz. Watch for: Small-enclosure bass extension at the measurement level does not guarantee the same response at high volume.
Buy the Genelec 8320A. It is rated higher for sound quality than the Devialet Phantom II 98 dB and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

Genelec 8320A: $1,700 per pair B&H Photo Video eBay
Pros: A measured 1.6dB span from 300Hz to 5kHz and preference scores of 5.52 standalone and 8.04 with an ideal subwoofer support accurate close-range monitoring. The waveguide helps control the balance between direct and reflected sound. GLM room calibration is useful for matching levels and placement in a compact setup. Measured bass extension of 67.4Hz (-3dB).
Cons: The -3dB point is about 67Hz, making a subwoofer important for lower bass and giving the larger 8330A a practical advantage without one. Calibration hardware is sold separately. The small woofer limits its intended listening distance and bass output; a favorable response-fit parameter is not evidence that it has uniquely well-damped bass or unusually high headroom.

Devialet Phantom II 98 dB: $2,998 per pair Devialet eBay
Pros: The manufacturer-supplied measurement shows unusually deep bass for the enclosure size: -3dB at 30Hz. Scores of 6.87 standalone and 7.95 with an ideal subwoofer suggest that its appeal is not limited to bass quantity. Integrated amplification and network playback can replace several components, and its 2.3dB midrange response span is reasonably even. Measured bass extension of 30Hz (-3dB).
Cons: Small-enclosure bass extension at the measurement level does not guarantee the same response at high volume. Stereo requires two units, and the integrated architecture offers less system flexibility than conventional monitors.
