Short answer: the MoFi SourcePoint 10. It ranks #27 of 222 bookshelf speakers by sound quality, rated 4.4/5, at $3,795. The Sonus Faber Lumina II Amator ranks #188, rated 3.0/5, at $2,000, $1,795 cheaper, which does not close the gap in sound quality.
The MoFi SourcePoint 10 is the better-sounding, deeper-bass pick. A large bookshelf speaker with a 10 inch concentric driver that acts like a point source, with a huge soundstage and strong, clean dynamics. Its bass reaches about 56Hz before falling 3dB, against 63Hz for the Sonus Faber Lumina II Amator. The catch: Like virtually all coincident designs, sounds notably bright pointed directly on-axis due to a deliberate treble lift (meant to compensate for the 28mm tweeter’s earlier beaming versus a typical 25mm/1” tweeter) combined with a diffraction dip/peak from the waveguide edge; needs about 15° of toe-out to sound neutral, and even then benefits from an extra 1-2dB of treble EQ.
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 10. It is rated higher for sound quality, and saving $1,795 with the Sonus Faber Lumina II Amator does not make up for the sound-quality gap.
