Short answer: the MoFi SourcePoint V10 Master Edition. It ranks #4 of 228 floorstanding speakers by sound quality, rated 4.8/5, at $7,995; the Radiant Acoustics Clarity 66 ranks #11, rated 4.6/5, and costs $7,998, so there is not much of a tradeoff to weigh.
The Radiant Acoustics Clarity 66 is the more accurate, deeper-bass pick. Highly accurate floorstanding speakers with Purifi woofers and bass deep enough to skip a subwoofer. Its measured preference score, a predictor of how neutral it sounds, is 6.01 against 5.00 for the MoFi SourcePoint V10 Master Edition. Its bass reaches about 32.2Hz before falling 3dB, against 38Hz for the MoFi SourcePoint V10 Master Edition. The catch: Vertical directivity is narrow and horizontal coverage is uneven, so listening height and placement affect tonal balance.
The case for the MoFi SourcePoint V10 Master Edition: Big floorstanding speakers with a 10 inch coaxial driver, precise imaging and bass deep enough to skip a subwoofer. The tradeoff: Moderate sensitivity (~89 dB) means amplifier power requirements higher than many alternatives.
Buy the MoFi SourcePoint V10 Master Edition. It is rated higher for sound quality than the Radiant Acoustics Clarity 66 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
