Short answer: the Sonus Faber Lumina II Amator. It ranks #77 of 100 bookshelf speakers by sound quality; the Wharfedale Diamond 9.1 ranks #79.
The case for the Sonus Faber Lumina II Amator: Solid bass extension for a bookshelf (F3 63Hz, F10 43Hz), reaching about 50Hz in-room. The tradeoff: 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.
On the Wharfedale Diamond 9.1 side: The first design was a pretty good sounding speaker. Set against that: All current new ones sold today are the crap version.
Buy the Sonus Faber Lumina II Amator if sound quality matters more than the price. Buy the Wharfedale Diamond 9.1 if the price matters more than sound quality.
If sound quality matters at all to you, skip both of these and look higher up the 100 bookshelf speakers instead.

The Two Speakers In Full
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.

Wharfedale Diamond 9.1: Discontinued
Pros: The first design was a pretty good sounding speaker, the speaker was then outsourced to China and lost 1.5kg and was made with cheap parts and sounds much worse. Slightly rolled off in the treble by about 3dB
Cons: All current new ones sold today are the crap version. Discontinued.
