Short answer: the Neumann KH420 on measured sound quality, the Yamaha HS8 on price. The Neumann KH420 ranks #5 of 113 powered bookshelf speakers, rated 4.8/5, at $11,198. The Yamaha HS8 ranks #36, rated 4.4/5, at $797.98, $10,400.02 cheaper.
What the Yamaha HS8 does well: ASR measurements support broadly neutral sound: a 2.3dB response span from 300Hz to 5kHz and 7.58 ideal-subwoofer score. Watch for: Its response and off-axis behavior are not as refined as the leading monitors.
The Neumann KH420 is the more accurate, 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 measured preference score, a predictor of how neutral it sounds, is 7.02 against 5.85 for the Yamaha HS8. Its bass reaches about 27.8Hz before falling 3dB, against 43.9Hz for the Yamaha HS8. The tradeoff: It is a large, heavy studio monitor rather than an easy desktop speaker.
Buy the Yamaha HS8 if the price is the priority over sound quality, or the Neumann KH420 if sound quality is the priority over the price.

Yamaha HS8: $797.98 per pair Amazon eBay
Same family: the Yamaha HS3 (smaller bookshelf, estimated 2.9/5), the Yamaha HS4 (smaller bookshelf, estimated 3.1/5), the Yamaha HS5 (smaller bookshelf, rated 3.6/5), the Yamaha HS7 (smaller bookshelf, ranked lower, rated 3.9/5) and the Yamaha HS8S (subwoofer, rated 3/5).
Pros: ASR measurements support broadly neutral sound: a 2.3dB response span from 300Hz to 5kHz and 7.58 ideal-subwoofer score. Measured -3dB bass extension of 43.9Hz gives useful weight for music, with straightforward analog connections and room-adjustment controls. Measured bass extension of 43.9Hz (-3dB).
Cons: Its response and off-axis behavior are not as refined as the leading monitors. Vertical positioning around the crossover matters, and a subwoofer remains useful for deep bass. Basic rear-panel controls do not replace measured 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°.
