Short answer: the Moondrop M4P MTM for midrange clarity, the Klipsch RP-500M II for easier placement at a lower price. The M4P MTM ranks #14 of 179 bookshelf speakers at $920 and crosses a 1-inch aluminum-magnesium dome to dual 4-inch carbon-cone woofers at 1.8kHz, but vertical placement is very fussy within about ±20° of the tweeter axis. The RP-500M II costs $389.99 and adds about a 5dB fill-in between 1-3kHz, though its 92-93dB sensitivity is an in-room rating.
Buy the Klipsch RP-500M II when the price outweighs sound quality for you, and the Moondrop M4P MTM when sound quality outweighs the price instead.
