Short answer: the Focal Alpha 65 EVO. It ranks #18 of 62 powered bookshelf speakers by sound quality at $400; the Adam Audio S2V ranks #43 and costs $3500, so there is not much of a tradeoff to weigh.
What the Focal Alpha 65 EVO offers: Very neutral, not quite as good as the Klasik 2020 in the midrange, but with better soundstage and instrument definition than the HS8 Watch for: Ignores sub-bass, and the LF/HF trim dials lack a center detent so getting back to flat takes trial and error. The reviewer’s original sample showed an odd distortion spike between 1.5-8kHz at 86dB SPL, though a second sample from Focal didn’t reproduce it - likely a defective unit rather than a design flaw.
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 Focal Alpha 65 EVO. It ranks higher for sound quality than the Adam Audio S2V and costs less, so there is no real case for the other one.
