Short answer: the KEF LS60. It ranks #2 of 15 powered floorstanding speakers by sound quality, rated 4.8/5, at $5,999.99; the Buchardt A700 ranks #8, rated 4.5/5, and costs $6,600, so there is not much of a tradeoff to weigh.
The KEF LS60 is the more accurate, deeper-bass choice. Wireless floorstanding speakers with extremely accurate sound and bass deep enough to skip a subwoofer. Its measured preference score, a predictor of how neutral it sounds, is 7.26 against 6.60 for the Buchardt A700. Its bass reaches about 23Hz before falling 3dB, against 51Hz for the Buchardt A700. The tradeoff: A diffraction dip around 9kHz can soften cymbal shimmer when aimed directly at the listener; 10-20 degrees of toe-out helps.
Why pick the Buchardt A700: Active floorstanding speakers with highly accurate sound, low distortion and a cardioid mode for placement near a wall. Watch for: Standard-mode bass crosses -3dB around 51Hz but continues to -6dB around 26Hz; it is not flat to the deepest advertised frequencies.
Buy the KEF LS60. It is rated higher for sound quality than the Buchardt A700 and costs less, which makes it the one to get unless you need something the other one does better.
