Sweet Spot,

I have also looked at the thread you provided and included a link for you to read from the Magnepan Users Group Forum on recommended power ratings for the different Magnepan speakers. Your receiver should not have a problem driving a set of MMGs or MG12s. As you can see from my signature, I am running two pairs of Magnepan IIIa speakers using a 5-channel Parasound amp rated at 140watts @8ohms and 200watts @4ohms. It is more than enough for me and my family in our dedicated home theater room in our house. Here's the link to the MUG Forum recommendations for each Magnepan ever made: http://www.integracoustics.com/MUG/MUG/articles/speakers.html
