Short answer: the MoFi SourcePoint 8. It ranks #17 of 223 bookshelf speakers by sound quality, rated 4.5/5, at $2,594. The Sonus Faber Lumina II Amator ranks #189, rated 3.0/5, at $2,000, $594 cheaper, which does not close the gap in sound quality.
The MoFi SourcePoint 8 is the better-sounding, deeper-bass option. A bookshelf speaker with an 8 inch concentric driver, neutral sound, excellent imaging, and wide dispersion that forgives placement. Its bass reaches about 52Hz before falling 3dB, against 63Hz for the Sonus Faber Lumina II Amator. 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.
What the Sonus Faber Lumina II Amator does well: A luxurious Italian bookshelf speaker with a gorgeous cabinet, solid bass for its size and wide, consistent dispersion. The catch: Very bright treble, running 3-6dB above the midrange depending on measurement angle: independently corroborated by other owners online, not just one reviewer’s opinion.
Buy the MoFi SourcePoint 8. It is rated higher for sound quality, and the $594 saving on the Sonus Faber Lumina II Amator is not enough to make up the difference.
