Short answer: the Audio First Cadentia 3 if sound quality matters most, the Ascend Acoustics CMT-340 SE2 if price matters most. The Audio First Cadentia 3 ranks #8 of 130 bookshelf speakers at $7199. The Ascend Acoustics CMT-340 SE2 ranks #23 at $798, $6401 cheaper.
What the Audio First Cadentia 3 offers: 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. Watch for: 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.
What the Ascend Acoustics CMT-340 SE2 offers: High-quality manufacturer Klippel NFS data shows 0.295dB on-axis average absolute deviation, 0.531 listening-window smoothness, and a strong 7.17 preference score with a subwoofer. Its dual 6.5-inch woofers, 92dB anechoic sensitivity, and 240W continuous power rating support high output and dynamics. Watch for: Bass rolls off early for the cabinet size, measuring 77.6Hz at -3dB, 64.5Hz at -6dB, and 48.3Hz at -12dB; the preference score without a subwoofer is only 4.51. The 4.35 sound-power directivity-index standard deviation also indicates more off-axis variation than the strongest designs, and the rear port needs placement clearance.
