Short answer: the Audio First Cadentia 3. It ranks #8 of 130 bookshelf speakers by sound quality; the Mission LX-3 MKII ranks #80.
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 Mission LX-3 MKII offers: A large affordable standmount with a 6.5-inch woofer, 88dB rated sensitivity and useful bass. ASR measured 48Hz estimated in-room extension, a controlled Q of 0.60, a 5.52 subwoofer-assisted preference score and reasonable +/-55-degree horizontal coverage. Watch for: On-axis smoothness of 0.217 and predicted in-room smoothness of 0.344 reveal clear response unevenness, with a -0.46dB-per-octave downward tilt. The 345mm-tall, 8.4kg cabinet is bulky and current US availability is limited.
Buy the Audio First Cadentia 3 when sound quality outweighs the price for you, and the Mission LX-3 MKII when the price outweighs sound quality instead.
