Short answer: the KRK Classic 5. It ranks #72 of 100 powered bookshelf speakers by sound quality (rated 3.4/5) at $319.99 and is still sold new; the NHT Pro M-00 ranks #98 (rated 1.7/5) and is discontinued, so it is only an option used.
The KRK Classic 5 is the better-sounding option. ASR’s Klippel data gives -3dB bass around 60Hz and a 5.99 preference score with an ideal subwoofer. The tradeoff: The native standalone score is 3.47 and the midrange span is a large 6.5dB.
What the NHT Pro M-00 does well: A sturdy metal enclosure, analog studio/consumer connections and selectable nearfield/farfield voicing give it practical features as an older powered monitor. The tradeoff: The review identifies a pronounced upper-bass cancellation, treble peaks and problematic vertical response, and strongly prefers the JBL 305P MKII in direct listening.
Buy the KRK Classic 5. It is rated higher for sound quality; the NHT Pro M-00 is no longer sold new.

KRK Classic 5: $319.99 per pair Amazon eBay
Pros: ASR’s Klippel data gives -3dB bass around 60Hz and a 5.99 preference score with an ideal subwoofer. Broad tonal correction can improve it, so it may be useful to someone willing to measure and EQ a basic studio setup. Measured bass extension of 60.1Hz (-3dB).
Cons: The native standalone score is 3.47 and the midrange span is a large 6.5dB. Excess treble and crossover/directivity errors keep it from being neutral out of the box, while low-bass distortion limits loud playback. Modeled EQ scores are not stock performance and do not demonstrate corrected distortion or dispersion.
