Short answer: the ADAM Audio D3v. It ranks #3 of 48 powered bookshelf speakers by sound quality, rated 4.5/5, at $349.99; the Sovox MiniMax3 ranks #14, rated 3.7/5, and costs $650, so there is not much of a tradeoff to weigh.
The ADAM Audio D3v is the more accurate, deeper-bass option. 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 3.84 for the Sovox MiniMax3. Its bass reaches about 50Hz before falling 3dB, against 66Hz for the Sovox MiniMax3. The tradeoff: A rising upper-frequency balance and vertical crossover interference keep it from being uniformly neutral at every angle; aim the tweeters toward ear height.
The case for the Sovox MiniMax3: A tiny aluminum coaxial monitor with a wide sweet spot, deep bass for its size and placement presets for desk or wall. The tradeoff: Output tops out around 86dB, with heavy compression and very high distortion as it gets there, so it only suits nearfield listening at modest volume.
Buy the ADAM Audio D3v. It is rated higher for sound quality than the Sovox MiniMax3 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

- Tonal accuracy above the bass: with a subwoofer taking the low end, the ADAM Audio D3v scores 7.6 against 6.5 for the Sovox MiniMax3 on the Spinorama preference scale. Its frequency response and off-axis sound are smoother, so voices and instruments sound closer to the recording.
