Short answer: the Kii THREE for better sound quality, the Buchardt A10 for the lower price. The Kii THREE ranks #3 of 119 powered bookshelf speakers, rated 4.9/5, at $16,970. The Buchardt A10 ranks #12, rated 4.7/5, at $4,300, $12,670 cheaper.
What the Kii THREE does well: Compact cardioid active speakers with extremely accurate sound and full range bass that walls barely color. 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: Active stand-mount speakers with accurate sound, deep bass for their size, and selectable DSP tunings to suit your room. 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.
