Short answer: the Philharmonic BMR Monitor for better sound quality, the Sonus Faber Lumina II Amator for the lower price. The Philharmonic BMR Monitor ranks #76 of 130 bookshelf speakers at $2200. The Sonus Faber Lumina II Amator ranks #106 at $2000, $200 cheaper.
What the Philharmonic BMR Monitor offers: Three-way design combining a 6” SB Acoustics mid-woofer, a 2.5” Tectonic balanced-mode radiator (BMR) for the midrange, and a ribbon tweeter - premium component choices relative to the asking price. A clear improvement over the V1: the earlier version’s overly hot, plateauing treble has been resolved, leaving a genuinely good in-room response outside of one specific area. Extremely wide horizontal radiation of about ±70-80°, creating an enveloping, wide soundstage that illuminates the sidewalls. Well-built, attractive cabinet. Midrange and tweeter show no stress or elevated distortion even at higher output - all the compression and distortion issues trace back to the mid-woofer alone. Watch for: A 1-2dB bump around 2-3kHz creates a “glare” on vocals, guitars, and strings that the reviewer noticed consistently across many tracks. The extremely wide radiation trades off against imaging precision - instrument placement became noticeably more diffuse and harder to pinpoint in a narrower, more reflective room, though it improved substantially in a larger, more open room with less sidewall interaction. A suspected resonance around 500Hz shows up as an imbalance in sound power and horizontal directivity measurements, loosely correlating with a vague sense of resonance the reviewer heard subjectively. Moderate sensitivity (about 84.1dB anechoic) and a mid-woofer that runs out of steam under real stress - distortion exceeds 3% even at 100Hz at 96dB, and the reviewer notes SB Acoustics’ published excursion specs tend to overstate real-world linear excursion by nearly 2x. Significant compression appears at 102dB: the woofer audibly unloads around 120Hz, and the ribbon tweeter also compresses heavily at high output - not well suited to very loud two-channel listening (above about 90dB at 4 meters). In-room bass rolls off around 50Hz, so a subwoofer is recommended for most music. Benefits noticeably from a few bands of EQ if available.
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 Philharmonic BMR Monitor when sound quality outweighs the price for you, and the Sonus Faber Lumina II Amator when the price outweighs sound quality instead.
The Sonus Faber Lumina II Amator is not a sound-quality pick. It sits near the bottom of the 130 bookshelf speakers; there are better options higher up.
