I have found the Sonas Fabers to be very well balanced. but much tamer top end than your GEs. Revel and Dynaudio pretty well balanced. You will be glad to get rid of the brittle distortion the AMT tweeters produce. Or if you like it, might I suggest the Elac? The MOFI 8 I thought was pretty good. 10 not so much. The CSS kits or built are very good.
