Short answer: the Buchardt Audio E50. It ranks #16 of 222 bookshelf speakers by sound quality, rated 4.5/5, at $4,600. The MoFi SourcePoint 10 ranks #27, rated 4.4/5, at $3,795, $805 cheaper, which does not close the gap in sound quality.
The Buchardt Audio E50 is the more accurate, deeper-bass option. A bookshelf speaker with remarkably deep bass for its size, a very neutral midrange, and low distortion, with no need to sit near a wall. Its measured preference score, a predictor of how neutral it sounds, is 5.84 against 4.16 for the MoFi SourcePoint 10. Its bass reaches about 40Hz before falling 3dB, against 56Hz for the MoFi SourcePoint 10. Watch for: A roughly 3dB dip in the upper midrange/lower treble softens attack and dialogue clarity: the reviewer’s main complaint, and it’s baked into the crossover rather than a directivity artifact, so it’s audible both on and off axis.
Why pick the MoFi SourcePoint 10: A large bookshelf speaker with a 10 inch concentric driver that acts like a point source, with a huge soundstage and strong, clean dynamics. The tradeoff: 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.
Buy the Buchardt Audio E50. It is rated higher for sound quality, and the $805 you would save on the MoFi SourcePoint 10 does not close the gap.
