Short answer: the ELAC Debut 3.0 DB63. It ranks #50 of 203 bookshelf speakers by sound quality, rated 4.2/5, at $499; the Aoshida Audio Musician Knight I V2 ranks #120, rated 3.6/5, and costs $2,099, so there is little reason to consider the other one.
The ELAC Debut 3.0 DB63 is the better-sounding, deeper-bass pick. 1” aluminum dome tweeter with a distinctive partial-lens waveguide design paired with a 6.5” third-generation aramid fiber cone woofer, in a robustly built cabinet for the price. Its bass reaches about 76Hz before falling 3dB, against 105.5Hz for the Aoshida Audio Musician Knight I V2. The tradeoff: A dip in the lower midrange (300-600Hz, about 1.5dB) reduces vocal warmth and can make voices sound slightly hollow.
What the Aoshida Audio Musician Knight I V2 does well: A substantial 6.5-inch standmount with unusually high measured sensitivity of 88.7dB. 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 ELAC Debut 3.0 DB63. It is rated higher for sound quality than the Aoshida Audio Musician Knight I V2 and costs less, which makes it the one to get unless you need something the other one does better.

ELAC Debut 3.0 DB63: $499.00 per pair Amazon Crutchfield eBay
Older model: the ELAC Debut 2.0 B6.2 (ranked lower, rated 3.5/5).
Same family: the ELAC Debut 3.0 DB53 (smaller bookshelf, estimated 3.9/5), the ELAC Debut 3.0 DF53 (smaller floorstanding, estimated 4.2/5), the ELAC Debut 3.0 DF63 (larger floorstanding, rated 4.2/5), the ELAC Debut 3.0 DC53 (smaller center, estimated 3.4/5) and the ELAC Debut 3.0 DC63 (larger center, estimated 3.5/5).
Pros: 1” aluminum dome tweeter with a distinctive partial-lens waveguide design paired with a 6.5” third-generation aramid fiber cone woofer, in a robustly built cabinet for the price. Shallow bass rolloff (F3 76Hz, F10 40Hz) allows placement close to a wall without excessive boominess, useful for smaller living rooms. Solid measured performance for the price: on-axis linearity within about 2.5dB, impedance dipping only to about 4.4 ohms (easily AVR-driven), and roughly 20-26dB of usable dynamic range. A clear improvement over its sibling ELAC DB62, which has a sibilance issue tied to the crossover that can’t be fixed with EQ. Wide horizontal radiation of about ±60°, giving a spacious soundstage. Distortion looks good at a moderate 86dB and still reasonable at 96dB. Takes well to EQ correction: the reviewer provides a specific filter set (a low-shelf boost at 650Hz plus peaking cuts/boosts at 550Hz, 660Hz, and 3kHz) that meaningfully smooths out its known deviations. Measured bass extension of 76Hz (-3dB), with a measured sensitivity of 86.2dB.
Cons: A dip in the lower midrange (300-600Hz, about 1.5dB) reduces vocal warmth and can make voices sound slightly hollow. A high-Q resonance around 650-750Hz shows up clearly in measurements, though the reviewer couldn’t reliably hear it in his own A/B testing. A dip around 2-3kHz (roughly 1-2dB) slightly reduces speech intelligibility and attack in the upper midrange. Directivity droops above about 2kHz as the midwoofer narrows toward its beaming frequency while the tweeter’s pattern behaves differently: an inherent trade-off of physically separated drivers that can’t be fully corrected without introducing other issues. Multitone distortion crosses the reviewer’s 3% threshold in the 200Hz-1kHz range, and adding a subwoofer at an 80Hz crossover only modestly reduces it. Toeing the speaker away from the listener loses noticeable top-end air and cymbal energy, giving a softer upper register. Practical loudness ceiling is around 90dB at typical listening distance before midrange distortion and bass attack begin to degrade. Still needs a subwoofer for extension below about 40Hz.

Aoshida Audio Musician Knight I V2: $2,099 per pair Aoshida Audio eBay
Pros: A substantial 6.5-inch standmount with unusually high measured sensitivity of 88.7dB. ASR’s Klippel data shows excellent sound-power smoothness of 0.125 and a well-damped bass alignment Q of 0.69, with useful in-room extension estimated at 43Hz. Measured bass extension of 105.5Hz (-3dB), with a measured sensitivity of 88.7dB.
Cons: The response tilts upward by 0.37dB per octave, so it will sound bright, and predicted in-room smoothness is a poor 0.16. At $2099/pair it is expensive for a little-known direct-sale brand, and each unusually deep cabinet weighs 35.3 lb.
