Short answer: the Ascend Acoustics Sierra-2EX V2. It ranks #41 of 222 bookshelf speakers by sound quality, rated 4.3/5, at $1,748. The Dynaudio Emit 20 ranks #133, rated 3.6/5, at $1,049, $699 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Ascend Acoustics Sierra-2EX V2 is the more accurate pick. A ribbon tweeter bookshelf speaker with hand matched pairs, a frequency response printout for each unit, and a long seven year warranty. Its measured preference score, a predictor of how neutral it sounds, is 5.88 against 4.22 for the Dynaudio Emit 20. The tradeoff: On-axis response is relatively uneven, with an average deviation of about 0.45dB, so a listener sitting dead center may notice more unevenness than with smoother AsciLab or Ascend towers.
The case for the Dynaudio Emit 20: Bookshelf speakers with unusually deep, low distortion bass for a two-way design and wide, consistent dispersion. The tradeoff: A resonance around 600-800Hz gives snares and similar percussion a muffled, flat quality lacking impact: confirmed as originating in the woofer itself (isolated via measurements of the raw driver out of the cabinet), and attempts at constrained-layer damping didn’t resolve it.
Buy the Ascend Acoustics Sierra-2EX V2. It is rated higher for sound quality, and the $699 you would save on the Dynaudio Emit 20 does not close the gap.
