Short answer: the Neumann KH 150 if sound quality matters most, the Adam Audio T8V if price matters most. The Neumann KH 150 ranks #8 of 113 powered bookshelf speakers, rated 4.8/5, at $3,398. The Adam Audio T8V ranks #92, rated 3.9/5, at $599.98, $2,798.02 cheaper.
Why pick the Adam Audio T8V: Measured -3dB extension of 39.6Hz gives useful bass depth for an affordable large monitor. The catch: The 6.31 ideal-subwoofer score and 3.0dB response span from 300Hz to 5kHz show less even tonal balance than stronger budget alternatives.
The Neumann KH 150 is the more accurate pick. An exceptionally tight 1.0dB response span from 300Hz to 5kHz supports neutral vocals and instruments. Its measured preference score, a predictor of how neutral it sounds, is 6.65 against 4.65 for the Adam Audio T8V. Watch for: A two-way nearfield monitor cannot match the largest three-way systems for deep-bass output at distance.
Buy the Adam Audio T8V if the price is the priority over sound quality, or the Neumann KH 150 if sound quality is the priority over the price.

Adam Audio T8V: $599.98 per pair Amazon eBay
Same family: the Adam Audio T5V (smaller bookshelf, rated 4/5) and the Adam Audio T7V (smaller bookshelf, ranked lower, rated 3.9/5).
Pros: Measured -3dB extension of 39.6Hz gives useful bass depth for an affordable large monitor. Analog inputs and basic shelf controls offer uncomplicated studio integration. Measured bass extension of 39.6Hz (-3dB).
Cons: The 6.31 ideal-subwoofer score and 3.0dB response span from 300Hz to 5kHz show less even tonal balance than stronger budget alternatives. Treble emphasis and crossover-region vertical cancellation make listening height important. Deep bass and an AMT tweeter do not by themselves imply accurate sound. A notch around 4.6kHz, where tweeter and woofer interact, and a hole below the tweeter axis mean the tweeter should sit at or above ear height.

Neumann KH 150: $3,398 per pair B&H Photo Video eBay
Same family: the Neumann KH80 DSP (smaller bookshelf, rated 4.6/5), the Neumann KH120 MKII (smaller bookshelf, rated 4.7/5), the Neumann KH 310 A (larger bookshelf, ranked lower, rated 4.6/5), the Neumann KH420 (larger bookshelf, ranked higher, rated 4.8/5) and the Neumann KH 750 DSP (subwoofer, rated 3.5/5).
Pros: An exceptionally tight 1.0dB response span from 300Hz to 5kHz supports neutral vocals and instruments. The measured ideal-subwoofer score is 8.38, with -3dB bass extension to 39.6Hz. DSP and optional MA 1 alignment offer useful control over room-related response errors. Measured bass extension of 39.6Hz (-3dB).
Cons: A two-way nearfield monitor cannot match the largest three-way systems for deep-bass output at distance. Keep the tweeter near ear height to avoid crossover-related changes off the vertical axis. MA 1 calibration requires additional equipment, and studio connections are less convenient than a consumer streaming system.
