Short answer: the Sonus Faber Sonetto II G2. It ranks #183 of 222 bookshelf speakers by sound quality, rated 3.1/5, at $3,500; 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 Sonetto II G2 is the better-sounding choice. An Italian bookshelf speaker with a silk dome tweeter, a stylish concrete and metal base and evenly behaved dispersion. The catch: Sounds notably bright pointed directly on-axis; toeing the speaker out about 30° reduces treble energy and sibilance meaningfully.
Why pick the ATC SCM19: A heavy, sealed pro style ATC bookshelf speaker with a very dense cabinet and low distortion at high volume. The tradeoff: Some stored energy resonance around 500-700Hz, 4dB bump around 700Hz.
Buy the Sonus Faber Sonetto II G2. It is rated higher for sound quality than the ATC SCM19 and costs less, which makes it the one to get unless you need something the other one does better.
