Short answer: the Audio First Cadentia 3 if sound quality matters most, the Ascend Acoustics Sierra-LX if price matters most. The Audio First Cadentia 3 ranks #7 of 222 bookshelf speakers, rated 4.7/5, at $7,199. The Ascend Acoustics Sierra-LX ranks #37, rated 4.3/5, at $1,598, $5,601 cheaper.
The Audio First Cadentia 3 is the more accurate pick. A large three way bookshelf speaker with near textbook accuracy, a big enveloping soundstage, and deep, punchy bass that stays clean when loud. Its measured preference score, a predictor of how neutral it sounds, is 7.55 against 6.63 for the Ascend Acoustics Sierra-LX. The catch: 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).
What the Ascend Acoustics Sierra-LX does well: A compact bookshelf speaker with very neutral, flat sound, a wide soundstage, and surprisingly deep bass in a bamboo cabinet. Watch for: Very low sensitivity at about 81dB, so it needs a genuinely powerful amplifier to reach normal listening levels.
