Have had some experience with Magnepan 3.3's. I was using my dma-90's bridged with output of 180 w/per channel, and couldn't flesh out the bass from the Maggies. The dealer lent me his DMA 150 at 150 wpc, lower wattage, but higher current and the sound was wonderful. For Maggies, go with brute strength for the dollar,such as older McCormick, or Bryston amps.
