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 Ascend Acoustics ELX Ribbon Tower ranks #12, rated 4.6/5, at $5,698, $2,297 cheaper, not enough of a saving to outweigh the sound-quality gap.
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 catch: Moderate sensitivity (~89 dB) means amplifier power requirements higher than many alternatives.
The Ascend Acoustics ELX Ribbon Tower is the more accurate option. Highly accurate three way bamboo towers with a ribbon tweeter, deep tight bass and a long warranty. Its measured preference score, a predictor of how neutral it sounds, is 6.97 against 5.00 for the MoFi SourcePoint V10 Master Edition. Watch for: Listening window smoothness measures a moderate 0.40 and on axis deviation runs 0.286dB average, both trailing the tighter figures posted by some smaller passive AsciLab and Ascend bookshelf models.
Buy the MoFi SourcePoint V10 Master Edition. It is rated higher for sound quality, and the $2,297 saving on the Ascend Acoustics ELX Ribbon Tower is not enough to make up the difference.
