Short answer: the MoFi SourcePoint 10, because the Zu Audio Method has a severe midrange suckout. The Zu measures about 90-90.7dB average through the 300Hz-3kHz vocal range, but a suckout in the 1.5-3kHz range drops as much as 19dB below the mean and removes attack and clarity from brass and woodwinds. The SourcePoint 10 delivers best-in-class sound power and directivity, though it is bright on-axis and costs $3,095 more.
The MoFi SourcePoint 10 is the more accurate, deeper-bass option. 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 measured preference score, a predictor of how neutral it sounds, is 4.16 against 0.25 for the Zu Audio Method. Its bass reaches about 56Hz before falling 3dB, against 92Hz for the Zu Audio Method. 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.
Buy the MoFi SourcePoint 10. It is rated higher for sound quality, and the $3,095 saving on the Zu Audio Method is not enough to make up the difference.
