Short answer: the Audio First Cadentia 3. It ranks #7 of 203 bookshelf speakers by sound quality, rated 4.7/5, at $7,199. The Sonus Faber Lumina II Amator ranks #172, rated 3.0/5, at $2,000, $5,199 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Audio First Cadentia 3 is the better-sounding, deeper-bass pick. Near-textbook measurements: excellent on-axis linearity, listening window, and directivity, with only minor deviations. Its bass reaches about 43Hz before falling 3dB, against 63Hz for the Sonus Faber Lumina II Amator. The tradeoff: A mild scoop through the upper midrange/lower treble slightly softens the attack of snares, hand claps, and sibilants: fixable with a single-band EQ (2.5kHz, +1dB, Q~1).
What the Sonus Faber Lumina II Amator does well: Solid bass extension for a bookshelf (F3 63Hz, F10 43Hz), reaching about 50Hz in-room. The catch: Very bright treble, running 3-6dB above the midrange depending on measurement angle: independently corroborated by other owners online, not just one reviewer’s opinion.
Buy the Audio First Cadentia 3. It is rated higher for sound quality, and the $5,199 you would save on the Sonus Faber Lumina II Amator does not close the gap.

Audio First Cadentia 3: $7199 per pair Audio First Designs eBay
Pros: Near-textbook measurements: excellent on-axis linearity, listening window, and directivity, with only minor deviations. Extremely low distortion and compression, holding steady even at 102dB with barely any loss. Very wide, consistent horizontal dispersion (~70 degrees) gives a big, enveloping soundstage with strong image specificity outside the speaker boundaries. Strong bass extension for a bookshelf (F3 43Hz, F10 26Hz) with a punchy, guttural mid-bass. Measured bass extension of 43Hz (-3dB), with a measured sensitivity of 86.4dB.
Cons: A mild scoop through the upper midrange/lower treble slightly softens the attack of snares, hand claps, and sibilants: fixable with a single-band EQ (2.5kHz, +1dB, Q~1). High-frequency dispersion narrows quickly above about 4kHz, so off-axis listeners lose some air and detail. Very high asking price for a bookshelf-class speaker, and the complete (finished) version has a long lead time; the loaner kit version ships as an unfinished cabinet you assemble and finish yourself.

Sonus Faber Lumina II Amator: $2000 per pair Crutchfield eBay
Pros: Solid bass extension for a bookshelf (F3 63Hz, F10 43Hz), reaching about 50Hz in-room. Decent sensitivity and wide, consistent horizontal dispersion (~60-70 degrees): better directivity than expected for a two-way design. Gorgeous, luxury-grade cabinet design. Measured bass extension of 63Hz (-3dB), with a measured sensitivity of 86.9dB.
Cons: Very bright treble, running 3-6dB above the midrange depending on measurement angle: independently corroborated by other owners online, not just one reviewer’s opinion. Causes audible sibilance and a forward, grainy character. Notably the brightest of three Sonus Faber models Erin’s Audio Corner has tested, even brighter than the brand’s own Sonetto II G2. A mechanical resonance/ringing artifact shows up around 1kHz in measurements. Needs a subwoofer for anything below about 50Hz.
