Short answer: the Neumann KH 310 A for better sound quality, the Adam Audio S2V for the lower price. The Neumann KH 310 A ranks #13 of 66 powered bookshelf speakers at $4400. The Adam Audio S2V ranks #45 at $3500, $900 cheaper.
What the Neumann KH 310 A offers: CEA2034 spinorama shows a near-perfect on-axis response with superb directivity control and minimal off-axis variation. Distortion measured very low at 96dB SPL/1m. Bass stays clean and dry without bloat, and vocals show no harshness. Tri-amplified design delivers 290W combined output and up to 116.3dB SPL. Watch for: An unidentified dip around 80Hz shows up in the measurements, which Neumann was asked to investigate. Bass response shifts somewhat with amplifier temperature. Distortion rises above 100% THD at the very bottom of the bass range, as expected at that extreme. Expensive at $4,400 per pair.
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 Neumann KH 310 A if sound quality matters more than the price. Buy the Adam Audio S2V if the price matters more than sound quality.
