Short answer: the Devialet Phantom Ultimate 98dB, if you are buying new. The Devialet Phantom II 98 dB ranks higher than the Kali Audio LP-UNF (#11 vs #45 of 105 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.
Why pick the Kali Audio LP-UNF: A practical compact desktop system with USB-C, analog inputs and Bluetooth, plus extensive placement switches. Watch for: The 2.9dB midrange span masks local response ripples; listening-window narrow-band deviation of 0.467 is behind the best monitors.
The Devialet Phantom II 98 dB is the more accurate, deeper-bass choice. 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 4.60 for the Kali Audio LP-UNF. Its bass reaches about 30Hz before falling 3dB, against 54Hz for the Kali Audio LP-UNF. The catch: 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 LP-UNF.

The Two Speakers In Full
Kali Audio LP-UNF: $349.00 per pair Amazon eBay
Same family: the Kali Audio LP-6 V2 (smaller bookshelf, rated 4.4/5) and the Kali Audio LP-8 V2 (smaller bookshelf, rated 4.1/5). See every Kali Audio LP generation.
Pros: A practical compact desktop system with USB-C, analog inputs and Bluetooth, plus extensive placement switches. Erin’s Klippel data gives -3dB bass around 54Hz and scores of 4.60 standalone and 6.67 with an ideal subwoofer. The low crossover and waveguide provide useful freedom of listening height for a two-way design, and moderate-level distortion is well controlled in the review. The 1.9kHz crossover gives vertical coverage of about ±30 to 40°, well beyond the typical ±10 to 15° of a two-way. Measured bass extension of 54Hz (-3dB), with a measured sensitivity of 88.1dB.
Cons: The 2.9dB midrange span masks local response ripples; listening-window narrow-band deviation of 0.467 is behind the best monitors. The review finds limiting around 91dB/1m per speaker. No dedicated subwoofer output means integration requires suitable external routing or bass management. Its strength is affordable close listening, not top-tier tonal accuracy or high-output room playback.

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. See every Devialet Phantom generation.
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.
