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. ASR’s revised measurement combines an 8.48 ideal-subwoofer preference score with a 1.7dB response span from 300Hz to 5kHz, supporting highly even vocal and instrumental balance. 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: The sealed three-way design combines 35.2Hz measured -3dB extension with low distortion in the review’s demanding playback tests. 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.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared.
