I have done this same comparison and the Coincidents are the way to go hands down. I have owned 4 Silverline models and 2 Coincident and kick my self everyday for selling my Coincident Super E III's, they are great speakers. The Coincident Partial E II IMHO are some of the best speakers for the money available. Silverlines are easier to drive, but are more hifi sounding to me. I am not a Dynaudio tweeter fan, I am much more of a Scanspeak guy. The Revelator tweeter in the Coincident is much more listenable to me than any Dynaudio product. Alan Yun is a nice guy and his speakers are OK, but if you truly want something that will sound good and keep you happy over time get the Coincidents...make sure you get the outrigger feet they are worth the cash.
Hope that helps.
