Short answer: the Kii THREE on measured sound quality, the Adam Audio T8V on price. The Kii THREE ranks #3 of 67 powered bookshelf speakers at $14000. The Adam Audio T8V ranks #53 at $349.99, $13650.01 cheaper.
What the Adam Audio T8V offers: Quite balanced and neutral, very close to the Yamaha HS8. Deeper bass than the HS8 Watch for: A crossover-region notch around 4.6kHz where tweeter and woofer interact, and a hole in the vertical response below the tweeter axis - keep the tweeter at or above ear height. Distortion is well controlled at 86dB SPL but gets messier at 96dB.
What the Kii THREE offers: A genuinely full-range active cardioid monitor. Erin measured a 28Hz F3, and boundary gain in his room kept useful response close to 20Hz. Four side/rear 6.5-inch woofers use DSP delay and cancellation to suppress rearward radiation above roughly 70-90Hz, reducing front-wall and sidewall interaction while the 5-inch midrange and waveguided tweeter maintain exceptionally smooth directivity. Six Ncore amplifier channels provide 1,500W total per cabinet, phase-exact mode offers precise impulse behavior, and Erin found imaging, tonal neutrality and left/right symmetry outstanding. Watch for: The protection limiter becomes evident above approximately 96dB at 1m; bass-heavy material can overdrive the compact woofers with an audible plop even though many tracks exceed 100dB at a four-meter seat. The BXT modules are the appropriate but very expensive solution for more deep-bass headroom. Erin preferred the treble control at -2dB because broad radiation around 3-5kHz could sound sharp. Phase-exact operation adds latency, while low-latency mode trades away some low-frequency correction. System cost, proprietary connectivity and 42-pound cabinets also narrow its audience.
Buy the Adam Audio T8V if the price is the priority over sound quality, or the Kii THREE if sound quality is the priority over the price.
Skip the Adam Audio T8V if sound quality matters to you. It ranks near the bottom of the 67 powered bookshelf speakers.

Adam Audio T8V: $699.98 per pair Amazon eBay
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.
Cons: The 5.42 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.

Kii THREE: $14,000 per pair Vintage King eBay
Pros: Exceptionally even measured balance: the 300Hz-5kHz response spans only 1.2dB, with preference scores of 7.06 standalone and 7.71 with an ideal subwoofer. Cardioid control reduces rearward low-midrange energy, while measured -3dB extension of 29.3Hz provides convincing full-range bass in a compact system.
Cons: Deep-bass output has limits: demanding low-frequency material at high levels can trigger compression or audible distress. The reviewer preferred a small treble reduction, so the high score is not a promise of ideal tonal balance for every listener. Linear-phase operation adds latency, and the system is expensive.
