Short answer: the Neumann KH420 on measured accuracy. Its spinorama is extended and flat on axis, matching Neumann’s published measurement to within 0.08dB, with well-controlled but narrow horizontal beamwidth at about ±55 degrees. The LP-8’s notes instead point to the newer V2 and concede the Eris 8 beats it by a little bit. The Kali Audio LP-8 is discontinued; its replacement is the Kali Audio LP-8 V2.
The case for the Kali Audio LP-8: Note the newer V2 is out which could be a little better. The tradeoff: Eris 8 has this beat by a little bit.
Buy the Neumann KH420. It is rated higher for sound quality, and the Kali Audio LP-8 is discontinued, so it is only available used.
