I know you are selling your Calipers, but the photos look like you did not biwire them (unless those are shotgunned wires). Biwiring the Calipers really makes them open up. Also, the Caliper and Duetta Signatures have a plastic screen over the bass ribbons, which go a long way to protecting them from inquisitive fingers. The Duetta Signatures and the Divas can also be screwed into the floor, so they can't be easily knocked over by toddlers.
I also have utilized the Calipers and the Maggie 1.6QR's as main speakers and concur that although the Calipers are incomparable in bass power and dynamics, the Maggie is more neutral, more coherent throughout and superior in the higher registers. A Vandersteen 2WQ added to the Maggies almost makes up for the difference in the bass.
