Short answer: the Kii THREE for better sound quality, the Buchardt A10 for the lower price. The Kii THREE ranks #3 of 68 powered bookshelf speakers, rated 4.9/5, at $16,970. The Buchardt A10 ranks #11, rated 4.7/5, at $4,300, $12,670 cheaper.
What the Kii THREE does well: Exceptionally even measured balance: the 300Hz-5kHz response spans only 1.2dB, with preference scores of 7.70 standalone and 8.35 with an ideal subwoofer. Watch for: Deep-bass output has limits: demanding low-frequency material at high levels can trigger compression or audible distress.
Why pick the Buchardt A10: The measured tuning combines 31.5Hz -3dB bass extension with preference scores of 7.28 standalone and 8.00 with an ideal subwoofer. Watch for: The rising treble balance can sound brighter on axis; toe-out or a different tuning may suit some rooms.
Buy the Kii THREE if sound quality is the priority over the price, or the Buchardt A10 if the price is the priority over sound quality.

The Two Speakers In Full
Kii THREE: $16,970 per pair Vintage King eBay
Pros: Exceptionally even measured balance: the 300Hz-5kHz response spans only 1.2dB, with preference scores of 7.70 standalone and 8.35 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. Measured bass extension of 28Hz (-3dB).
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.

Buchardt A10: $4300 per pair Buchardt Audio eBay
Pros: The measured tuning combines 31.5Hz -3dB bass extension with preference scores of 7.28 standalone and 8.00 with an ideal subwoofer. A 1.9dB response span from 300Hz to 5kHz supports broadly even mids, and selectable DSP tunings offer useful flexibility. Measured bass extension of 30Hz (-3dB).
Cons: The rising treble balance can sound brighter on axis; toe-out or a different tuning may suit some rooms. Deep-bass demands cause compression before the largest monitors reach their limits. A subwoofer with appropriate high-pass filtering can improve headroom; alternate presets should not be assumed to share the quoted scores.
