Short answer: the Neumann KH420 for the higher ranking, the Edifier R2850DB for the lower price. The Neumann KH420 ranks #2 of 20 powered bookshelf speakers at $10500. The Edifier R2850DB ranks #19 at $424.99, $10075.01 cheaper.
On the Edifier R2850DB side: 3 way speaker. Set against that: Quite large and heavy.
The case for the Neumann KH420: CEA2034 spinorama shows an extended, flat on-axis response that matches Neumann’s own published measurement to within 0.08dB at its one. The tradeoff: Horizontal beamwidth, while well controlled, is on the narrow side at about ±55 degrees.
Buy the Edifier R2850DB if the price matters more than the ranking. Buy the Neumann KH420 if the ranking matters more than the price.

Edifier R2850DB: $424.99 Amazon
Pros: 3 way speaker. Deeper bass and more of a fun listen compared to the neutral sound of the HS8. Shockingly close to the HS8 at half the price.
Cons: Quite large and heavy

Neumann KH420: $10500 Bhphotovideo
Pros: CEA2034 spinorama shows an extended, flat on-axis response that matches Neumann’s own published measurement to within 0.08dB at its one minor dip (around 60Hz), with excellent off-axis behavior. Predicted in-room response is smooth and rated “excellent” by the reviewer. Horizontal beamwidth of about ±55 degrees is very well controlled and stays consistent across frequency. Distortion is low at 86dB SPL/1m. Exceptionally high sustained output capability - the reviewer needed to “hold on for dear life” during extreme-level testing at 7 feet, with bass output described as making the entire house resonate. Reviewer’s overall verdict was “Great,” placing it on the recommended list and calling it a speaker “you could buy and forget about upgrading ever again.”
Cons: Horizontal beamwidth, while well controlled, is on the narrow side at about ±55 degrees. Vertical directivity is more limited than horizontal - the reviewer recommends staying within about ±30 degrees of the reference axis (just below the tweeter waveguide edge). Distortion rises noticeably in the bass region at 96dB SPL/1m, with an unusual 3rd-harmonic uptick appearing near 10kHz at that output level. At 106dB SPL/1m, the tweeter’s protection limiting engages and the clipping indicator activates - a real, measurable output ceiling despite the speaker’s otherwise very high capability. Very expensive.
