I have apogee caliper signature II's and Magnepan 3.6R, and the Maggies are way better than the calipers. I know the calipers are not Diva's, but it's the closest comparison I can give you. Maggies are also very amp dependant, I've been through quite a few amps, each time you unveil a little more of their potential. They are great with tubes, but Cary V12 Monoblocks at 200/watts do not provide enough power. I'm using a Krell FPB200 which has the power but not the warmth and finesse that is needed.
