Short answer: the Polk R200. It ranks #69 of 100 bookshelf speakers by sound quality at $799; the Sonus Faber Lumina II Amator ranks #77 and costs $2000, so there is not much of a tradeoff to weigh.
What the Polk R200 gets right: Two-way design with a 6.5” midwoofer and 1” ring radiator tweeter, giving reasonably tight, well-defined imaging. The catch: A resonance and associated distortion increase around 800Hz-1kHz creates a “tinny,” occasionally glaring quality on certain instruments and vocals.
On the Sonus Faber Lumina II Amator side: Solid bass extension for a bookshelf (F3 63Hz, F10 43Hz), reaching about 50Hz in-room. Set against that: 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 Polk R200. It ranks higher for sound quality than the Sonus Faber Lumina II Amator and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip the Sonus Faber Lumina II Amator. It ranks near the bottom of the 100 bookshelf speakers, so look higher up the list instead.

The Two Speakers In Full
Polk R200: $799.00 Amazon
Pros: Two-way design with a 6.5” midwoofer and 1” ring radiator tweeter, giving reasonably tight, well-defined imaging. Neutral through most of the midrange (roughly 200Hz-1kHz). On-axis response holds within about 1.5dB up to 10kHz. About 20dB of usable dynamic range (76dB to 96dB) before more significant compression sets in. Reasonably close to a 4-ohm nominal load, giving some flexibility with amplifier choice, though a dedicated 4-ohm-capable amp is still recommended.
Cons: A resonance and associated distortion increase around 800Hz-1kHz creates a “tinny,” occasionally glaring quality on certain instruments and vocals, confirmed both by ear and in the frequency-response and distortion measurements. Above about 10kHz, the ring-radiator tweeter takes on an artificial, “digital-esque” quality, then falls off quickly above 16kHz. F3 of 74Hz and F10 of 50Hz mean there’s essentially no meaningful bass “thump” below about 60Hz - a subwoofer is strongly recommended even just to restore basic kick-drum presence. The ring radiator tweeter’s dispersion narrows sharply above about 8kHz, so the speaker should be aimed close to on-axis (no more than 5-10° of toe-out). Vertical listening position is fairly critical - moving more than a few degrees above or below the tweeter line causes a noticeable timbre shift due to a gap in the crossover region. Multitone distortion spikes substantially (to around 10%) in the 600Hz-1kHz region at higher output levels (around 96dB/1m), meaning the glare gets worse the louder it’s played. At the highest tested output (102dB, 26dB of dynamic range), the woofer shows clear signs of struggling; crossing to a subwoofer around 80-100Hz helps prevent bottoming out but doesn’t fully eliminate the compression.

Sonus Faber Lumina II Amator: $2000 Crutchfield
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.
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.
