I should clarify my situation. I own the 1.3SE's. I can get the Silverline for $800 less than what I could get by selling the Dynaudios. I think even the older SR17 models used Dynaudio drivers but I'm not sure if they are the equal of the drivers used in the 1.3SE's. So, I was wondering if I would lose much by going with the Silverlines. In any event, I have since decided to stay with the 1.3SE's for now and possibly check out the newer model of the Silverlines, the SR 17.5. Thanks for the suggestions.
