Rebbi-
The problem is that it is very hard to find somewhere where you can listen to speakers, without a salesman obnoxious presence...What I would suggest is to get to a show where you can hear some/most of these speakers. Israel was at the show in Manhattan in 2014 and is likely to be there/RMAF/Capitol Audiofest in 2015. Most of the time, if you're patient you can get the music you feel is most critical cued up for a listen. If you're recognized as really serious, you might even get an extended demo before or after hours, with the possibility of a show special price. In the meantime, since you are very happy w the amp/speaker sound you now have for 90% of what you listen to, you can enjoy that, let the stuff break in more, and get used to how different things affect the sound. I know how hard patience can be, but short of buying, comparing, and selling the loser, there are not too many options these days, esp. w boutique products. Unless of course, you can find a B&M store who stocks Coincident, Ref 3A, Tekton and who knows what else.
