Short answer: the ADAM Audio D3v. It ranks #3 of 48 powered bookshelf speakers by sound quality, rated 4.5/5, at $349. The HiVi Swan X3 ranks #10, rated 3.9/5, at $179, $170 cheaper, which does not close the gap in sound quality.
The ADAM Audio D3v is the more accurate pick. Small desktop monitors with very accurate sound and surprisingly deep bass for their size, plus a simple USB connection. Its measured preference score, a predictor of how neutral it sounds, is 5.37 against 4.04 for the HiVi Swan X3. Watch for: A rising upper-frequency balance and vertical crossover interference keep it from being uniformly neutral at every angle; aim the tweeters toward ear height.
What the HiVi Swan X3 does well: An affordable small coaxial desktop pair with fairly balanced sound for the money. The tradeoff: Not a flat reference monitor: the response spans 5.0dB from 300Hz to 5kHz and trends upward toward the treble.
Buy the ADAM Audio D3v. It is rated higher for sound quality, and the $170 saving on the HiVi Swan X3 is not enough to make up the difference.
