I have used a pair of Maggie 1.6s with a little Naim Nait5i (50wpc) and they sounded ok. I hear a lot of people saying you really need 250wpc to make them sing. I have the opportunity to buy a pair of Maggie 3.6s very cheap in another country where I spend some months each year. I was hoping my Simaudio i7 at 150wpc would be enough power for these. Magnepan won't answer this question firmly - what do you think ?
