Short answer: the Mesanovic CDM65. It ranks #2 of 119 powered bookshelf speakers by sound quality, rated 4.9/5, at $5,998. The Neumann KH 310 A ranks #20, rated 4.6/5, at $4,998, $1,000 cheaper, a saving that is not big enough to make up the sound-quality gap.
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.
The Mesanovic CDM65 is the more accurate pick. High end monitors with extremely accurate sound and deep bass, plus a cardioid mode that helps in difficult rooms. Its measured preference score, a predictor of how neutral it sounds, is 7.07 against 6.21 for the Neumann KH 310 A. The tradeoff: Cardioid operation and bass tuning affect placement and output, so use the appropriate mode for the room.
Buy the Mesanovic CDM65. It is rated higher for sound quality, and the $1,000 saving on the Neumann KH 310 A is not enough to make up the difference.
