Short answer: the Klipsch RP-600M II. It ranks #123 of 222 bookshelf speakers by sound quality, rated 3.7/5, at $449.99; the Aoshida Audio Musician Knight I V2 ranks #132, rated 3.6/5, and costs $2,099, so there is little reason to consider the other one.
The Klipsch RP-600M II is the more accurate, deeper-bass option. Bookshelf speakers with a large horn tweeter, wide soundstage, high efficiency and bi-amp ready terminals. Its measured preference score, a predictor of how neutral it sounds, is 5.64 against 4.50 for the Aoshida Audio Musician Knight I V2. Its bass reaches about 70Hz before falling 3dB, against 105.5Hz for the Aoshida Audio Musician Knight I V2. The tradeoff: On-axis, the treble runs notably hot (even hotter than the original Klipsch RP-600M in some respects) and needs about 20° of toe-out or the grille installed to sound balanced.
What the Aoshida Audio Musician Knight I V2 does well: Substantial standmount speakers with a beryllium tweeter, fairly high sensitivity and good bass extension for a 6.5 inch woofer. Watch for: The response tilts upward by 0.37dB per octave, so it will sound bright, and predicted in-room smoothness is a poor 0.16.
Buy the Klipsch RP-600M II. It is rated higher for sound quality than the Aoshida Audio Musician Knight I V2 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
