Short answer: the March Audio Sointuva AWG. It ranks #5 of 222 bookshelf speakers by sound quality, rated 4.7/5, at $4,150. The MoFi SourcePoint 8 ranks #17, rated 4.5/5, at $2,594, $1,556 cheaper, not enough of a saving to outweigh the sound-quality gap.
The case for the MoFi SourcePoint 8: A bookshelf speaker with an 8 inch concentric driver, neutral sound, excellent imaging, and wide dispersion that forgives placement. The catch: Like other coincident designs, produces diffraction dips around 4kHz and 7kHz when pointed directly on-axis; needs about 10-15° of toe-out to smooth those out.
The March Audio Sointuva AWG is the more accurate, deeper-bass choice. A Purifi powered bookshelf speaker with extremely flat sound, very low distortion, and unusually deep bass for its size. Its measured preference score, a predictor of how neutral it sounds, is 6.95 against 5.15 for the MoFi SourcePoint 8. Its bass reaches about 40Hz before falling 3dB, against 52Hz for the MoFi SourcePoint 8. The tradeoff: Correct listening axis sits about 7° above the tweeter line, which means shorter stands (around 24”) than typical bookshelf stands are sold at: get the height wrong and the sound scoops out in the mid/high frequencies.
Buy the March Audio Sointuva AWG. It is rated higher for sound quality, and the $1,556 you would save on the MoFi SourcePoint 8 does not close the gap.
