I've owned the AN E's and you should note they are not quite as efficient as they are quoted but still fairly good. I think 8wch may be ok if your not listening too loud you should be fine. I tried 8wch on them in my room with good results but ultimately found they needed a little more juice. 16wch plenty. They are very good speakers but I found they didn't soundstage that well in my room and somewhat "one bass noted". but I have a hard room to work with so not totally their fault. mind you other speakers I've had seem to be ok in the same room my Living Voice R3, Omegas SAM's(OMG huge sound stage).
I also heard the O/96's in the same sound room when I demoed the AN/E's I picked the AN's but you may have a different pick. I also listened to a 3 way Dynaudio speaker (wish I could remember them $5k price range 2 years ago) and they actually, at half the price, sounded better IMO then the divores but in no way as efficient.
To be honest I'm not a fan of the Devore house sound after listening to both the Gibbon 8 and O/96's, so add that to what I've said.
I would buy the AN/E's again if all silver wired/coil wired and I had the right room for them, thinking two corners here as they are IMO best in the corners.
