Short answer: the Neumann KH420 on measured sound quality, the Adam Audio T7V on price. The Neumann KH420 ranks #5 of 113 powered bookshelf speakers, rated 4.8/5, at $11,198. The Adam Audio T7V ranks #93, rated 3.9/5, at $479.98, $10,718.02 cheaper.
The case for the Adam Audio T7V: Audioholics’ measurements provide useful evidence about the midrange and treble, with a digitized 2.4dB response span from 300Hz to 5kHz. The catch: Correct listening height is important for the two-way crossover.
The Neumann KH420 is the better-sounding, deeper-bass pick. A 1.2dB response span from 300Hz to 5kHz, 8.14 ideal-subwoofer score and 27.8Hz measured -3dB extension combine accurate mids with genuinely deep bass. Its bass reaches about 27.8Hz before falling 3dB, against 65Hz for the Adam Audio T7V. The catch: It is a large, heavy studio monitor rather than an easy desktop speaker.
Buy the Adam Audio T7V when the price outweighs sound quality for you, and the Neumann KH420 when sound quality outweighs the price instead.

Adam Audio T7V: $479.98 per pair Amazon eBay
Same family: the Adam Audio T5V (smaller bookshelf, rated 4/5) and the Adam Audio T8V (larger bookshelf, ranked higher, rated 3.9/5).
Pros: Audioholics’ measurements provide useful evidence about the midrange and treble, with a digitized 2.4dB response span from 300Hz to 5kHz. Basic tonal controls and analog connections suit a straightforward nearfield system. Measured bass extension of 65Hz (-3dB).
Cons: Correct listening height is important for the two-way crossover. Basic shelf controls offer less adjustment flexibility than parametric room correction.

Neumann KH420: $11,198 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 150 (smaller bookshelf, ranked lower, rated 4.8/5), the Neumann KH 310 A (smaller bookshelf, ranked lower, rated 4.6/5) and the Neumann KH 750 DSP (subwoofer, rated 3.5/5).
Pros: A 1.2dB response span from 300Hz to 5kHz, 8.14 ideal-subwoofer score and 27.8Hz measured -3dB extension combine accurate mids with genuinely deep bass. Its three-way design and low distortion at normal levels make it particularly attractive for larger listening distances and dynamic material. Measured bass extension of 27.8Hz (-3dB).
Cons: It is a large, heavy studio monitor rather than an easy desktop speaker. Vertical alignment matters around the crossover regions. Bass distortion rises as playback levels increase, and the measured high-level limits still apply despite the substantial drivers and amplifiers. Horizontal beamwidth is well controlled but on the narrow side at about ±55°.
