Short answer: the MoFi SourcePoint 8. It ranks #17 of 203 bookshelf speakers by sound quality, rated 4.5/5, at $2,594. The Sonus Faber Lumina II ranks #144, rated 3.4/5, at $1,600, $994 cheaper, which does not close the gap in sound quality.
The case for the Sonus Faber Lumina II: Handmade in Italy with a gloss-finished front baffle and black leather-wrapped cabinet: genuinely nice-looking speaker with real brand cachet. The tradeoff: Not a neutral speaker: has a persistent high-frequency boost/lift that makes it sound forward and bright, present whether pointed directly at the listener or toed out.
The MoFi SourcePoint 8 is the more accurate, deeper-bass pick. 8” twin-drive concentric driver paired with a 1.25” soft dome tweeter, in a diffraction-reducing baffle design; rated 47Hz-30kHz. Its measured preference score, a predictor of how neutral it sounds, is 5.15 against 3.81 for the Sonus Faber Lumina II. Its bass reaches about 52Hz before falling 3dB, against 60Hz for the Sonus Faber Lumina II. The tradeoff: 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.
Buy the MoFi SourcePoint 8. It is rated higher for sound quality, and the $994 you would save on the Sonus Faber Lumina II does not close the gap.

The Two Speakers In Full
Sonus Faber Lumina II: $1,600 per pair Crutchfield eBay
Same family: the Sonus Faber Lumina I (smaller bookshelf, estimated 3.3/5), the Sonus Faber Lumina III (smaller floorstanding, estimated 3.5/5), the Sonus Faber Lumina V (larger floorstanding, estimated 3.6/5) and the Sonus Faber Lumina Center I (center, estimated 3.5/5).
Pros: Handmade in Italy with a gloss-finished front baffle and black leather-wrapped cabinet: genuinely nice-looking speaker with real brand cachet. Bass extension is competitive for the size, reaching about 50 Hz in-room with mild compression and good distortion figures, so higher output levels and greater listening distances aren’t a problem down to that point. About 20 dB of dynamic range at typical listening levels (73 dB at 4m), which comfortably covers most music without the tonal balance shifting as instruments and vocals peak. Off-axis behavior is consistent: toeing the speakers 20-30 degrees out doesn’t meaningfully change the in-room high-frequency character, so placement flexibility is good once you’ve dialed in the tonal balance. Measured bass extension of 60Hz (-3dB), with a measured sensitivity of 86dB.
Cons: Not a neutral speaker: has a persistent high-frequency boost/lift that makes it sound forward and bright, present whether pointed directly at the listener or toed out. A slightly nasal quality traced to a resonance around 1 kHz that EQ can address. The reviewer needed to trim treble by about 4 dB on his preamp to get the tonal balance he wanted, meaning most listeners will want equalization available to fully enjoy this speaker. At roughly the same $1,000ish price point, alternatives like the Ascend Acoustics Sierra 1 V2 measure more linear (with a tradeoff in distortion and crossover-region directivity), and the Dynaudio Emit 20 offers deeper bass extension and lower compression at the cost of a more deliberately colored tonal signature.

MoFi SourcePoint 8: $2594 per pair Crutchfield eBay
Same family: the MoFi SourcePoint 10 (larger bookshelf, ranked lower, rated 4.4/5) and the MoFi SourcePoint 888 (floorstanding, rated 4.7/5).
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.
