Short answer: the Devialet Phantom Ultimate 98dB, if you are buying new. The Devialet Phantom II 98 dB ranks higher than the Kali Audio IN-5 (#10 vs #26 of 100 powered bookshelf speakers) but is discontinued; its replacement, the Devialet Phantom Ultimate 98dB, is rated 4.4/5 at $3,998 and is still sold new.

What the Kali Audio IN-5 does well: The active three-way layout separates bass duties from the coaxial mid/tweeter, giving flexible listening geometry. The tradeoff: Local listening-window irregularities remain despite the small overall midrange span.
The Devialet Phantom II 98 dB is the more accurate, deeper-bass pick. The manufacturer-supplied measurement shows unusually deep bass for the enclosure size: -3dB at 30Hz. Its measured preference score, a predictor of how neutral it sounds, is 6.87 against 5.12 for the Kali Audio IN-5. Its bass reaches about 30Hz before falling 3dB, against 45Hz for the Kali Audio IN-5. The tradeoff: Small-enclosure bass extension at the measurement level does not guarantee the same response at high volume.
Buy the Devialet Phantom Ultimate 98dB, the replacement for the discontinued Devialet Phantom II 98 dB; it is rated higher for sound quality than the Kali Audio IN-5.

Kali Audio IN-5: $898 per pair Amazon B&H Photo Video eBay
Same family: the Kali Audio IN-8 V2 (larger bookshelf, rated 4.4/5) and the Kali Audio IN-UNF (larger bookshelf, ranked lower, rated 3.3/5).
Pros: The active three-way layout separates bass duties from the coaxial mid/tweeter, giving flexible listening geometry. Erin’s data shows a 1.8dB midrange response span and -3dB bass around 45Hz, with scores of 5.12 standalone and 7.13 with an ideal subwoofer. Placement switches and balanced inputs help integrate it into a studio; moderate-level distortion is well controlled in the existing review. Measured bass extension of 45Hz (-3dB).
Cons: Local listening-window irregularities remain despite the small overall midrange span. The review reports midrange distortion rising above 3% at 96dB and a brighter perceived balance at closer distances. Limiting makes it unsuitable for demanding farfield playback. Coaxial construction improves geometry but does not remove response errors or guarantee unlimited output.

Devialet Phantom II 98 dB: $2,998 per pair Discontinued Devialet eBay
Newer model: the Devialet Phantom Ultimate 98dB, ranked lower, estimated 4.4/5.
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. Discontinued.
