Short answer: the AsciLab C8C. It ranks #1 of 119 powered bookshelf speakers by sound quality (rated 4.9/5); the Neumann KH 310 A ranks #20 (rated 4.6/5).
The AsciLab C8C is the more accurate pick. Excellent large powered monitors, with extremely accurate sound and bass deep enough to skip a subwoofer. Its measured preference score, a predictor of how neutral it sounds, is 7.70 against 6.21 for the Neumann KH 310 A. The catch: The result applies to the revised measured configuration; confirm that the speaker’s tuning matches it.
The case for the Neumann KH 310 A: Sealed three-way studio monitors with balanced sound, useful deep bass, and low distortion even when played hard. The tradeoff: Its measured tonal balance is not as even as the Neumann KH 150 or the best coaxial alternatives.
Buy the AsciLab C8C. It is rated higher for sound quality than the Neumann KH 310 A.
