Short answer: the March Audio Sointuva AWG. It ranks #5 of 131 bookshelf speakers by sound quality, rated 4.7/5, at $4,150. The MoFi SourcePoint 8 ranks #17, rated 4.5/5, at $2,594, $1,556 cheaper, not enough of a saving to outweigh the sound-quality gap.
The case for the MoFi SourcePoint 8: 8” twin-drive concentric driver paired with a 1.25” soft dome tweeter, in a diffraction-reducing baffle design; rated 47Hz-30kHz. 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.
The case for the March Audio Sointuva AWG: Purifi drivers deliver exceptionally low midrange distortion (the reviewer calls them “world class”) paired with bass extension unusually deep for a bookshelf (F3 40Hz, F10 30Hz), reaching down to about 30Hz in-room with some boundary reinforcement. The catch: Correct listening axis sits about 7° above the tweeter line, which means shorter stands (around 24”) than typical bookshelf stands are sold at: get the height wrong and the sound scoops out in the mid/high frequencies.
Buy the March Audio Sointuva AWG. It is rated higher for sound quality, and the $1,556 you would save on the MoFi SourcePoint 8 does not close the gap.

The Two Speakers In Full
MoFi SourcePoint 8: $2594 per pair Crutchfield eBay
Pros: 8” twin-drive concentric driver paired with a 1.25” soft dome tweeter, in a diffraction-reducing baffle design; rated 47Hz-30kHz. Notably more neutral and true-to-source than its sibling SourcePoint 10, which the reviewer found a bit too bright in the treble by comparison: measured about 4-5dB less high-frequency output. Excellent imaging: passed multiple stereo-panning and depth tests, including smooth continuous left-to-right pans without wobble and correct front-to-back layering of vocals versus percussion. Wide horizontal dispersion of about ±60°, broader than the reviewer expected from a coaxial design, and forgiving enough in placement that about 10° of toe-out variance and moving above or below the tweeter axis both still sound good. Excellent dynamic range and compression linearity: about 26dB of headroom up to 102dB/1m equivalent, with issues only appearing below about 60Hz. 8-ohm nominal impedance made it easy to drive on everything from a budget Denon AVR to a high-end Macintosh amplifier. No significant evidence of woofer-cone modulation distortion affecting the tweeter, even at 96dB/1m. Measured bass extension of 52Hz (-3dB), with a measured sensitivity of 86.3dB.
Cons: 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. The rear-ported cabinet (two ports) means it can’t be placed too close to a wall without the bass becoming overblown: the reviewer settled on about 2 feet of clearance. F3 of 52Hz and F10 of 43Hz mean genuine deep bass tops out in the mid-40s Hz in-room: a subwoofer is still needed for true low-end extension. Harmonic distortion crosses the reviewer’s 3% threshold at 96dB (though it’s second-order and less audibly significant), and multitone distortion becomes noticeably more audible at that same output level. Vertical response doesn’t perfectly mirror horizontal, since the cabinet is a rectangle rather than a perfect square around the driver.

March Audio Sointuva AWG: $4150 per pair March Audio eBay
Older model: the March Audio Sointuva (ranked lower, rated 4.6/5).
Pros: Purifi drivers deliver exceptionally low midrange distortion (the reviewer calls them “world class”) paired with bass extension unusually deep for a bookshelf (F3 40Hz, F10 30Hz), reaching down to about 30Hz in-room with some boundary reinforcement. Sensitivity tolerance band measured extremely tight at 1.6-1.73dB, indicating excellent build consistency. Estimated in-room response is exceptionally smooth and neutral: one of the flattest the reviewer has measured, with none of the usual coloration descriptors (bright, boomy, nasal, shouty) needed to describe it. Distortion stays so low even at loud volumes that there’s no audible warning cue before you’re playing dangerously loud: a backhanded compliment to how clean it sounds. At $4150/pair, ranked among the reviewer’s top three bookshelf speakers in that price range. Measured bass extension of 40Hz (-3dB), with a measured sensitivity of 82.4dB.
Cons: Correct listening axis sits about 7° above the tweeter line, which means shorter stands (around 24”) than typical bookshelf stands are sold at: get the height wrong and the sound scoops out in the mid/high frequencies. Moderate-low sensitivity (~82dB) is roughly 3dB below a typical bookshelf speaker, meaning close to double the amplifier power is needed for the same output; low impedance also calls for a 4-ohm capable amp. Horizontal radiation holds a wide ±60° only up to about 3kHz before narrowing: tighter top-end dispersion than the reviewer’s preferred ±60-70° through the treble, and the reason he left the previous generation off his all-time top-five list. Multitone distortion rises above the reviewer’s personal 3% threshold in the 1-2kHz region, though it wasn’t audible in his listening. Not intended to be crossed over with a subwoofer at 80Hz: designed to play full-range down to 40-50Hz, so pairing it with a sub and cutting it off early wastes its bass capability. Best positioned about 3 feet from the rear wall, requiring more floor space than many bookshelf speakers.
