Short answer: the Audio First Cadentia 3. It ranks #7 of 203 bookshelf speakers by sound quality (rated 4.7/5) at $7,199 and is still sold new; the Philharmonic BMR (v1) ranks #41 (rated 4.3/5) and is discontinued, so it is only an option used. The Philharmonic BMR (v1)’s replacement, the Philharmonic BMR Monitor, is rated 3.6/5.
The Audio First Cadentia 3 is the more accurate, deeper-bass option. Near-textbook measurements: excellent on-axis linearity, listening window, and directivity, with only minor deviations. Its measured preference score, a predictor of how neutral it sounds, is 7.55 against 4.86 for the Philharmonic BMR (v1). Its bass reaches about 43Hz before falling 3dB, against 62Hz for the Philharmonic BMR (v1). The tradeoff: A mild scoop through the upper midrange/lower treble slightly softens the attack of snares, hand claps, and sibilants: fixable with a single-band EQ (2.5kHz, +1dB, Q~1).
Why pick the Philharmonic BMR (v1): Large three-way combining a Scan-Speak 7-inch paper/carbon woofer, 2.5-inch Tectonic balanced-mode midrange and RAAL 64-10 ribbon. The catch: The measured 83dB sensitivity and roughly 4-ohm load demand meaningful external amplification.

Audio First Cadentia 3: $7199 per pair Audio First Designs eBay
Pros: Near-textbook measurements: excellent on-axis linearity, listening window, and directivity, with only minor deviations. Extremely low distortion and compression, holding steady even at 102dB with barely any loss. Very wide, consistent horizontal dispersion (~70 degrees) gives a big, enveloping soundstage with strong image specificity outside the speaker boundaries. Strong bass extension for a bookshelf (F3 43Hz, F10 26Hz) with a punchy, guttural mid-bass. Measured bass extension of 43Hz (-3dB), with a measured sensitivity of 86.4dB.
Cons: A mild scoop through the upper midrange/lower treble slightly softens the attack of snares, hand claps, and sibilants: fixable with a single-band EQ (2.5kHz, +1dB, Q~1). High-frequency dispersion narrows quickly above about 4kHz, so off-axis listeners lose some air and detail. Very high asking price for a bookshelf-class speaker, and the complete (finished) version has a long lead time; the loaner kit version ships as an unfinished cabinet you assemble and finish yourself.

Philharmonic BMR (v1): $2,395 per pair Discontinued eBay
Newer model: the Philharmonic BMR Monitor, ranked lower, rated 3.6/5.
Pros: Large three-way combining a Scan-Speak 7-inch paper/carbon woofer, 2.5-inch Tectonic balanced-mode midrange and RAAL 64-10 ribbon. Erin measured approximately +/-1.5dB linearity from 80Hz upward, very broad +/-40-degree-or-better horizontal coverage and about 83dB/2.83V/1m sensitivity. The port is tuned in the mid/low-30Hz region without audible chuffing, the midrange provides unusually expansive staging, and distortion remained subjectively unobtrusive. Measured bass extension of 62Hz (-3dB), with a measured sensitivity of 83dB.
Cons: The measured 83dB sensitivity and roughly 4-ohm load demand meaningful external amplification. A 1-2dB shelf below about 300Hz reduces warmth unless corrected, while a response/impedance feature near 250-300Hz corresponded with Erin’s sense of resonance. The ribbon produces narrower vertical than horizontal radiation, and second-order high-frequency distortion plus dynamic enhancement near 3kHz appeared in testing. This was an earlier cabinet/version, not the current v2. Discontinued.
