Milimetr, unless I missed it, I do not see what is your preference as far as music goes. You say that the Wilson's and the Magico's are more dynamic than the GH's. I would agree that for 'headbangers' that that statement would hold true. Also, if your room is very large, then again the Wilson's and/or the Magico's would fill the space probably better. The GH's are basically small monitors ( note I don't say mini-monitors) and as such their ability to move big air is limited. OTOH, if you are looking for finesse in the reproduction of instruments and particularly un-amplified string instruments, IMHO the GH's are superior to the others.
The room and the type of music you like listening to is a factor in this issue.
With SF's one tends to get a speaker that is voiced more for classical/small jazz ensembles vs. Rock or large bombastic music. The Jadis amp you are using is also IMHO voiced somewhat similarly to the SF's. BTW, have you considered a Sub to extend the bottom end of the SF's ( which is what I suspect you are missing in the GH's vs. The V2's and the Wilsons). I would think that a Torus sub and the SF GH's would come in at a lower price than the V2's or certainly the Mini 2'and could be the answer for you.
