I have the N801 and having tried the following amps: Bryston 4BST, CJ Premier 11a, Pass X250, and now Pass X350, I am convinced that high-powered solid state is the way to go. 200 watts/ch is the minimum. These speakers will handle as much power as your amp can output.
Looks like a lot of people are suggesting bi-amping them as well. I will have to go try that...some day.
