Short answer: the Sonus Faber Lumina II. It ranks #91 of 130 bookshelf speakers by sound quality at $1600; the ATC SCM19 ranks #119 and costs $3750, which makes this an easy call rather than a real tradeoff.
What the Sonus Faber Lumina II offers: Handmade in Italy with a gloss-finished front baffle and black leather-wrapped cabinet - genuinely nice-looking speaker with real brand cachet. Bass extension is competitive for the size, reaching about 50 Hz in-room with mild compression and good distortion figures, so higher output levels and greater listening distances aren’t a problem down to that point. About 20 dB of dynamic range at typical listening levels (73 dB at 4m), which comfortably covers most music without the tonal balance shifting as instruments and vocals peak. Off-axis behavior is consistent - toeing the speakers 20-30 degrees out doesn’t meaningfully change the in-room high-frequency character, so placement flexibility is good once you’ve dialed in the tonal balance. Watch for: 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. A slightly nasal quality traced to a resonance around 1 kHz that EQ can address. The reviewer needed to trim treble by about 4 dB on his preamp to get the tonal balance he wanted, meaning most listeners will want equalization available to fully enjoy this speaker. At roughly the same $1,000ish price point, alternatives like the Ascend Acoustics Sierra 1 V2 measure more linear (with a tradeoff in distortion and crossover-region directivity), and the Dynaudio Emit 20 offers deeper bass extension and lower compression at the cost of a more deliberately colored tonal signature.
What the ATC SCM19 offers: Harmonic distortion at 96dB SPL/1m stays generally low across the range aside from the spike tied to the 700-800Hz resonance. Sealed (unported) cabinet avoids port noise and resonance, and the extremely dense, heavy-duty enclosure (17.8kg/39lb each) reflects ATC’s pro-audio build standards. Watch for: Some stored energy resonance around 500-700hz, 4dB bump around 700hz. Not recommended for the price. CEA2034 spinorama and predicted in-room response both show a very uneven overall balance - a broad accentuation from midrange to treble paired with too little bass - along with directivity error. At 96dB SPL/1m, harmonic distortion tied to the 500-700Hz resonance rises to a level the reviewer says “should not be there.”
Buy the Sonus Faber Lumina II. It ranks higher for sound quality than the ATC SCM19 and costs less, so there is no real case for the other one.
The ATC SCM19 is not a sound-quality pick. It sits near the bottom of the 130 bookshelf speakers; there are better options higher up.
