Ake, Conrad-Johnson is a reputable firm known for customer support. They also make nice sounding solid state amps (I use one). The Maggie 1.6's are a 4 Ohm load, you might be better off with one of their high current amps (2300 or 2500 series). These amps also have almost double the power (still within the recommendations of Magnaplanar), and while I am not a Maggie owner (I do like their stuff) popular opinion
around here suggests the maggies like power.
