Short answer: the KEF Q Concerto Meta. It ranks #11 of 223 bookshelf speakers by sound quality, rated 4.6/5, at $1,399.99; the Sonus Faber Lumina II Amator ranks #189, rated 3.0/5, and costs $2,000, so there is not much of a tradeoff to weigh.
The KEF Q Concerto Meta is the better-sounding, deeper-bass option. A neutral three way bookshelf speaker that sounds consistent from seat to seat, with smooth treble that many rivals at its price lack. Its bass reaches about 53Hz before falling 3dB, against 63Hz for the Sonus Faber Lumina II Amator. Watch for: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment.
The case for the Sonus Faber Lumina II Amator: A luxurious Italian bookshelf speaker with a gorgeous cabinet, solid bass for its size and wide, consistent dispersion. 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 KEF Q Concerto Meta. It is rated higher for sound quality than the Sonus Faber Lumina II Amator and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
