Short answer: the Kii Seven. It ranks #23 of 118 powered bookshelf speakers by sound quality, rated 4.6/5, at $7,790. The ADAM Audio S3V ranks #31, rated 4.5/5, at $6,999.98, $790.02 cheaper, a saving that is not big enough to make up the sound-quality gap.
The case for the Kii Seven: A smaller sibling of the Kii THREE that uses the same active wave focusing idea: side and rear woofers are driven by DSP to cancel sound going backward, giving a cardioid pattern so nearby walls color the bass far less than with a conventional box. The catch: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured Kii THREE, which shares its cardioid design.
What the ADAM Audio S3V does well: A three-way midfield monitor from ADAM’s S Series: a 9” HexaCone woofer and a 4” dome/cone midrange take over below the tweeter, so the midrange is handled by a dedicated driver instead of a woofer working near its limits. The catch: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured two-way ADAM Audio S2V.
Buy the Kii Seven. It is rated higher for sound quality, and the $790.02 saving on the ADAM Audio S3V is not enough to make up the difference.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: Kii Seven 4.3 to 4.9; ADAM Audio S3V 4.2 to 4.8). Treat this verdict as provisional.

The Two Speakers In Full
Kii Seven: $7,790 per pair Estimated Vintage King eBay
Same family: the Kii THREE (larger bookshelf, ranked higher, rated 4.9/5).
Pros: A smaller sibling of the Kii THREE that uses the same active wave focusing idea: side and rear woofers are driven by DSP to cancel sound going backward, giving a cardioid pattern so nearby walls color the bass far less than with a conventional box. Two 6.5” woofers, a 5” midrange and a waveguided 1” tweeter get 600W of amplification per speaker, and Kii specifies ±0.5dB from 100Hz to 10kHz with bass to 40Hz (-3dB). It accepts analog XLR, TRS and AES digital, and adds Wi-Fi streaming, Bluetooth and Dante, so it works as a studio monitor or a complete wireless hi-fi system.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured Kii THREE, which shares its cardioid design. Bass extension stops around 40Hz, short of the larger Kii THREE, and the optional Kii Control remote costs extra.

ADAM Audio S3V: $6,999.98 per pair Estimated B&H Photo Video eBay
Same family: the ADAM Audio S2V (smaller bookshelf, ranked higher, rated 4.6/5), the ADAM Audio S3H (larger bookshelf, ranked lower, estimated 4.5/5), the ADAM Audio S5V (larger bookshelf, ranked lower, estimated 4.4/5) and the ADAM Audio S5H (larger bookshelf, ranked lower, estimated 4.4/5).
Pros: A three-way midfield monitor from ADAM’s S Series: a 9” HexaCone woofer and a 4” dome/cone midrange take over below the tweeter, so the midrange is handled by a dedicated driver instead of a woofer working near its limits. ADAM specifies 32Hz to 50kHz and 124dB peak output from 850W of amplification, so it plays loud and full-range without a subwoofer. Like the ADAM Audio S2V it uses a handmade S-ART folded-ribbon tweeter in an HPS waveguide and DSP with selectable voicings, a 6-band parametric EQ and delay for fitting it to the room, with analog XLR and AES digital inputs.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured two-way ADAM Audio S2V. It is a heavy, deep cabinet meant for stands in a treated room, and its strengths are wasted at desk distances.
