Short answer: the Sonus Faber Lumina II. It ranks #158 of 222 bookshelf speakers by sound quality, rated 3.4/5, at $1,600; the ATC SCM19 ranks #209, rated 2.4/5, and costs $3,750, which makes this an easy call rather than a real tradeoff.
The Sonus Faber Lumina II is the better-sounding choice. Handmade Italian bookshelf speakers with leather-wrapped cabinets, competitive bass for their size and flexible placement. The catch: Not a neutral speaker: has a persistent high-frequency boost/lift that makes it sound forward and bright, present whether pointed directly at the listener or toed out.
The ATC SCM19 is the more accurate pick. A heavy, sealed pro style ATC bookshelf speaker with a very dense cabinet and low distortion at high volume. Its measured preference score, a predictor of how neutral it sounds, is 4.61 against 3.81 for the Sonus Faber Lumina II. The tradeoff: Some stored energy resonance around 500-700Hz, 4dB bump around 700Hz.
Buy the Sonus Faber Lumina II. It is rated higher for sound quality than the ATC SCM19 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
