Short answer: the Kali Audio LP-6 V2. It ranks #19 of 62 powered bookshelf speakers by sound quality at $398; the Adam Audio S2V ranks #43 and costs $3500, so there is not much of a tradeoff to weigh.
What the Kali Audio LP-6 V2 offers: Outstandingly neutral active monitor for the money, with no audible amplifier hiss in Erin’s listening and excellent horizontal directivity from the contoured waveguide. Erin measured 42Hz F3 and on-axis linearity within approximately -2.51/+1.99dB. The pair remains respectably linear to roughly 102dB at 1m, the front port controls turbulence, and rear DIP switches provide practical boundary-placement profiles plus LF/HF trims. Balanced XLR/TRS and unbalanced RCA inputs broaden compatibility; Erin needed only about +1.5dB near 8kHz for his preferred amount of air. Watch for: A vertical directivity disturbance around 1.5-2kHz makes ear height important; desk or console reflections and ceiling bounce can expose the crossover lobing, so absorption may help. Limiting becomes visible above 96dB/1m, and from 76 to 96dB the low-frequency/midband balance drops by roughly 1dB, making this better as a nearfield or modest-distance monitor than a far-field high-output system. There is no digital input or network control, and each speaker needs AC power and a separate signal cable.
What the Adam Audio S2V offers: CEA2034 spinorama shows excellent driver blending through an imperceptible crossover between the 7” woofer and AMT tweeter, with distortion measured 70dB down at 1kHz. The 350W amplifier was the first the reviewer tested that didn’t run out of power on demand, delivering over 120dB SPL per pair. Watch for: An intentional shelving curve creates a dip in the low bass response, roughly 200-500Hz. The rotary-encoder control interface is non-intuitive, and the companion PC app requires serial-number registration with settings that only take effect after a manual “write” step that takes 5-10 seconds and produces audible ticks and pops. Expensive at $3,500 per pair.
Buy the Kali Audio LP-6 V2. It ranks higher for sound quality than the Adam Audio S2V and costs less, so there is no real case for the other one.
