Short answer: the KEF R3. It ranks #15 of 131 bookshelf speakers by sound quality, rated 4.5/5, at $2,200; the MoFi SourcePoint 10 Master Edition ranks #68, rated 3.8/5, and costs $3,799, so there is little reason to consider the other one.
What the KEF R3 does well: True three-way stand-mount with a 6.5-inch woofer below KEF’s 5-inch Uni-Q midrange/1-inch tweeter. Watch for: The low-frequency alignment rolls gradually rather than delivering high-output sub-bass; KEF specifies 58Hz +/-3dB and Erin’s high-level data supports using an 80Hz subwoofer crossover.
The case for the MoFi SourcePoint 10 Master Edition: A high-sensitivity 10-inch concentric design with a refined crossover, adjustable treble and amplifier-friendly impedance. Watch for: The cabinets are unusually large and heavy for stand-mount speakers, and suitable stands add expense and floor space.
Buy the KEF R3. It is rated higher for sound quality than the MoFi SourcePoint 10 Master Edition and costs less, which makes it the one to get unless you need something the other one does better.

The Two Speakers In Full
KEF R3: $2,200 per pair Amazon eBay
Pros: True three-way stand-mount with a 6.5-inch woofer below KEF’s 5-inch Uni-Q midrange/1-inch tweeter. Erin measured approximately 86-87dB/2.83V/1m sensitivity, exceptionally low sub-1% distortion at 86dB and orderly directivity in both planes. The coaxial geometry maintains image stability across seats, while Flexible Port Technology avoids the strong midrange port resonance common to rear-vented competitors. A 110W Parasound drove it successfully in Erin’s listening. Measured bass extension of 35.2Hz (-10dB), with a measured sensitivity of 87dB.
Cons: The low-frequency alignment rolls gradually rather than delivering high-output sub-bass; KEF specifies 58Hz +/-3dB and Erin’s high-level data supports using an 80Hz subwoofer crossover. Narrow high-frequency features and natural Uni-Q narrowing toward the top octave make toe angle audible, although off-axis tracking remains smooth. Sensitivity is moderate, the cabinet weighs almost 30 lb, and this original R3 lacks the Meta successor’s MAT absorber.

MoFi SourcePoint 10 Master Edition: $3,799 per pair MoFi Electronics eBay
Pros: A high-sensitivity 10-inch concentric design with a refined crossover, adjustable treble and amplifier-friendly impedance. Local Spinorama scores of 4.76 raw and 6.77 with a subwoofer combine with 42Hz extension and broad controlled radiation. Measured bass extension of 56.4Hz (-3dB).
Cons: The cabinets are unusually large and heavy for stand-mount speakers, and suitable stands add expense and floor space. A mild response contour remains despite the premium Master Edition crossover.
