Short answer: the MoFi SourcePoint 888. It ranks #8 of 228 floorstanding speakers by sound quality, rated 4.7/5, at $5,495; the Ascend Acoustics ELX Ribbon Tower ranks #12, rated 4.6/5, and costs $5,698, so there is little reason to consider the other one.
What the MoFi SourcePoint 888 does well: Excellent floorstanding speakers for the money, with near full range bass and effortless dynamics. The tradeoff: A significant investment, best ordered from a dealer with a good return policy.
The Ascend Acoustics ELX Ribbon Tower is the more accurate choice. 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 6.09 for the MoFi SourcePoint 888. 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.
