Short answer: the JBL Studio 630. It ranks #78 of 131 bookshelf speakers by sound quality at $699; the Sonus Faber Lumina II Amator ranks #107 and costs $2000, so there is not much of a tradeoff to weigh.
What the JBL Studio 630 offers: Excellent directivity linearity: harmonics of the same instrument stay collocated in the soundstage instead of drifting between positions, giving precise, stable imaging that holds up well into higher frequencies where many speakers start to beam and narrow. Good compression behavior - mid-bass stays taut and controlled from low to high volume without the sound falling apart or distorting as you turn it up. A pleasant, controlled mid-bass bump in the 60-100 Hz range adds punch to kick drums without bleeding into an uncontrolled boom on bass guitar. Horizontal radiation holds steady off-axis (about ±60°), so toe-in isn’t fussy. Compared directly to its predecessor, the JBL Studio 530, the reviewer would pick the 630 - smoother trend line through the upper mids and treble, and likely more dynamic headroom - as long as you’re willing to EQ. Watch for: Noticeable mid-range dip/scoop relative to the higher frequencies - not dramatic, but audibly “missing” something by the second or third track. Some tracks read as forward or aggressive around 2 kHz, like the upper frequencies are jumping out at you rather than sitting in stage depth. Needs EQ to bring the mid-range back up to be fully recommendable; without EQ available, the reviewer says he’d look at a different speaker entirely. Measured sensitivity (about 83.2dB) runs noticeably below the 85dB manufacturer spec, likely a byproduct of the mid-range dip skewing the average downward.
What the Sonus Faber Lumina II Amator offers: Solid bass extension for a bookshelf (F3 63Hz, F10 43Hz), reaching about 50Hz in-room. Decent sensitivity and wide, consistent horizontal dispersion (~60-70 degrees) - better directivity than expected for a two-way design. Gorgeous, luxury-grade cabinet design. Watch for: 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. Causes audible sibilance and a forward, grainy character. Notably the brightest of three Sonus Faber models Erin’s Audio Corner has tested, even brighter than the brand’s own Sonetto II G2. A mechanical resonance/ringing artifact shows up around 1kHz in measurements. Needs a subwoofer for anything below about 50Hz.
Buy the JBL Studio 630. It ranks higher for sound quality than the Sonus Faber Lumina II Amator and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip the Sonus Faber Lumina II Amator. It ranks near the bottom of the 131 bookshelf speakers, so look higher up the list instead.
