Short answer: the Dynaudio X14 for better sound quality, the ELAC Uni-Fi 2.0 UB52 for the lower price. The Dynaudio X14 ranks #32 of 56 bookshelf speakers at $1500. The ELAC Uni-Fi 2.0 UB52 ranks #37 at $599, $901 cheaper.
What the Dynaudio X14 offers: 1” silk-dome tweeter and 5.7” magnesium-silicate-polymer woofer in a compact two-way stand-mount, rated at 85dB sensitivity. Watch for: CEA2034 spinorama shows an uneven on-axis response from the lack of a waveguide to control tweeter beam width, plus a port resonance that boosts the lower midrange and imperfect crossover matching between the drivers.
On the ELAC Uni-Fi 2.0 UB52 side: Wide, smooth horizontal directivity - beamwidth holds to about ±60 degrees up to 8kHz before narrowing. Set against that: Dipped 3db from 1.5-3khz.
Buy the Dynaudio X14 if sound quality matters more than the price. Buy the ELAC Uni-Fi 2.0 UB52 if the price matters more than sound quality.

Dynaudio X14: $1500 Discontinued
Pros: 1” silk-dome tweeter and 5.7” magnesium-silicate-polymer woofer in a compact two-way stand-mount, rated at 85dB sensitivity.
Cons: CEA2034 spinorama shows an uneven on-axis response from the lack of a waveguide to control tweeter beam width, plus a port resonance that boosts the lower midrange and imperfect crossover matching between the drivers. Too much energy in the lower and upper treble reads as bright, and directivity narrows at higher frequencies rather than staying controlled. The reviewer’s verdict: out of the box, the objective performance isn’t that great, though EQ can make it a satisfying speaker. Discontinued.

ELAC Uni-Fi 2.0 UB52: $599.00 Amazon
Pros: Wide, smooth horizontal directivity - beamwidth holds to about ±60 degrees up to 8kHz before narrowing. Vertical directivity is substantially better than average, giving more listening-height leeway than most two-way bookshelf speakers.
Cons: Dipped 3db from 1.5-3khz. On-axis response shelves down above 1.5kHz along with multiple resonances, leading the reviewer to predict it will “likely sound dull.” Nasty resonance at 600hz - audible as an actual buzzing artifact on some recordings (the reviewer demonstrated it with an Eva Cassidy track), and it shows up as a sharp distortion spike exceeding 4% at 585Hz when driven to 96dB SPL/1m. Not recommended.
