IMO you'd be best looking at the Arcam FMJ A32 if you can get one in the states. Its a superb integrated amp in its own right but married with a decent power amp (i.e. the Arcam P35) you'd have a superb set-up and they drive your Dynadious with ease...
The problem is you cannot bi-amp Dynaudios.
However, I think you can use two P35 in mono mode as monoblocks, if I remember well.
I haven't heard the P35; I'm sure I would like it, as I'm a big Arcam fan. But I remember that my A65 Plus wasn't a good match for my A42s. I found the sound too soft. Of course, the A65 was only 40 W, and we know Dynaudios are power hungry. Maybe with the P35 the result will be much better, as they have more power. But I have a hunch that maybe something more dynamic, like a Bryston amp, could be better.
Arcam does have distribution in the US. Audiophile Systems used to be the distributor. I don't know who is handling the brand right now, but I'm sure you can find Arcam in the US.
