Did you look up their own view of which amp is best for Maggies? http://www.magnepan.com/faq#receivers
"Class A/B amplifier designs that come close to doubling power at 4 ohms have a long and successful track record."
Not sure when was this written though. See the part about class D amp.
"A new type of amplifier (Class D) has become more popular because it is a "green" design and uses less power plus it is smaller in size compared to conventional amplifier designs. We have heard reports of Class D amplifiers shutting down when driving 4 ohm loads or sound quality that is less-than-desirable. Quite frankly, some sound very poor on Maggies. However, more recent designs of high-end models are much better. Because we do not have the time to determine which models of Class D designs are compatible with Maggies, we must take a conservative approach. Direct-coupled, Class A/B designs with high current capability have proven a good choice for many decades."
I am happy with my Aragon 8008-->SMGc
