Short answer: the Kali IN-UNF for a coherent nearfield system. Its desk-mounted bass module and time-aligned coincident satellites make it a specialized but ingenious ultra-nearfield setup. The NHT Pro M-00 has a cast aluminum-zinc enclosure that doubles as an amplifier heatsink plus RCA and XLR/TRS inputs, but Amir identified a sudden upper-bass suck-out that affects many commonly-used notes.
On the Kali Audio IN-UNF side: Ingenious ultra-nearfield system: a desk-mounted bass module uses two opposed 4.5-inch woofers below 280Hz, while the satellites use time-aligned 4-inch/1-inch coincident drivers. Set against that: This is a very specialized system rather than a general desktop-speaker recommendation.
Buy the Kali Audio IN-UNF. It is rated higher for sound quality, and the NHT Pro M-00 is discontinued, so it is only available used.

The Two Speakers In Full
Kali Audio IN-UNF: $699 per pair Kali Audio eBay
Pros: A specialized ultra-nearfield system with coaxial satellites and an opposed-woofer bass module designed to sit on the desk. Erin found it worked much better when positioned using Kali’s placement template, with useful agreement between the intended response and close-range moving-microphone measurements. DSP placement controls and varied inputs make it a thoughtful solution for the right desk.
Cons: The intended desk geometry is part of the acoustic design. The bass module and prescribed spacing occupy considerable desk space and may conflict with large monitors. It is not designed for arbitrary room placement.

NHT Pro M-00: $498 per pair (used market; originally $249 each) Discontinued eBay
Pros: A sturdy metal enclosure, analog studio/consumer connections and selectable nearfield/farfield voicing give it practical features as an older powered monitor. Measured bass extension of 83.3Hz (-3dB).
Cons: The review identifies a pronounced upper-bass cancellation, treble peaks and problematic vertical response, and strongly prefers the JBL 305P MKII in direct listening. Discontinued.
