Your friend will definitely want something with reserve power - preferably something that has at least 100 w/ch into 8 ohms and doubles (or nearly doubles) into 4 ohms. If you give those speakers the right power / current, they'll really sing. While I don't have personal experience with either, I think Wirehead's advice of investigation Musical Fidelity's stuff and/or Bryston is excellent advice - the MF stuff is really good looking on top of being very well reviewed.
I don't think it's the Dynaudio's that are giving your friend the over-brightness, particularly if he was listening to a Parasound driving them. I own a pair of the 1.1's (as well as the 3.0's) and I wouldn't use "bright" as an adjective for them at all. -Kirk
