Are you talking 2 channel or will you use it for 5.1 or 6.1? I have Paradigm Studio 60's, and the 1804 can drive them ok in 2 channel. Put it in 5 channel mode with a pair of Studio 20's as the rear and a CC center, and the amp dies. Not enough to shut down or anything, but you will be close to clipping it. There isn't a big enough power supply to power the Paradigms. The Dynaudios are less efficent than the Paradigms, so I imagine this effect will be worse.
