Short answer: the Mission LX-3 MKII. It ranks #138 of 222 bookshelf speakers by sound quality (rated 3.6/5); the Sonus Faber Lumina II Amator ranks #188 (rated 3.0/5).
What the Sonus Faber Lumina II Amator does well: 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.
The Mission LX-3 MKII is the better-sounding choice. Large affordable standmount speakers with a 6.5 inch woofer, useful bass and easy to drive sensitivity. The catch: On-axis smoothness of 0.217 and predicted in-room smoothness of 0.344 reveal clear response unevenness, with a -0.46dB-per-octave downward tilt.
