Sorry Mrtennis - I've got the 20.1's biamped with 1400 wpc total power, and I still wouldn't say they are especially dynamic. They are alot of other great things - natural, spacious, tonally balanced, large soundstage - but I would not put dynamic on the top of the list of their strengths. I am still working on though - and with the new custom crossover (on its way), that may open things up a bit. They need A LOT of amplification - be prepared to spend at least as much as the speaker in amplification!
