I would try to listen to all demo's you can at stores or friends homes if possible for starters. You have gone through a lot of speakers. Everyone has a different opinion on what they like. I would suggest Dynaudio Contour 3.4's and depending how far you can stretch you budget maybe the 5.4's. The 5.4's have the esotar2 tweeters and a little more bass.
I have the Confidence C1's and the soundstage is huge - the depth is great along with the imaging. Dynamics are also great. In my opinion they do need a sub and I do have a REL B3 (had it before the C1's). The Rel although very musical dont seem to have the response as the lower end of the C1's. To me it sounds slow. I would love a dyn sub but you need to have a sub-out from your pre which I dont have to intergrate properly.
Just another idea.
