Salk HT3, SF Cremona M, Magnepan 3.7 or ML Ethos?

Help! :) I have been getting by with old Panasonic SB6's which are said to have an electrostatic sound for a piston type speaker design. Obviously they are pretty old monitors, but one thing they do well is (pinpoint) image with good width and moderate depth. But alas, I am finally ready to get some real (or at least modern) speakers.

I have heard the HT3's and liked the sound and look of them. They threw up a huge soundstage, but perhaps at the expense of the "pinpoint" imaging I am used to, and seemed exaggerated (e.g. silhouette of singers too large). However, I am not sure if I heard them in the best setup as they were very far from the rear wall (like 15ft) and in a huge room (maybe 35' square or even bigger). This may also have made the image seem entirely behind the plane of the speakers whereas I think a little closer is nicer (to me).

I have also heard the 3.7's in a dealer showroom, presumably properly setup. I felt like the big panels were "blocking" some of the sound and the soundstage was entirely between the panels, which made it compressed without much space between instruments, etc. Highly resolving and detailed, but lacked "air" (which the HT3s did very well). That room was probably 13'x18' or maybe slightly larger. I was somewhat disappointed given the stellar reviews. In fact, I felt the 1.7's (in a different room) in some respects sounded better.

I have not heard the Cremona M but did hear Olympica Monitors briefly at a different dealer. The room was probably 17' square, the Olympica's were maybe 2 feet off the rear wall. Since I only got 5-10mins with them, I barely got a sense but there was something nice about the SF sound that has me curious to hear a used model I might actually afford, hence the Cremona M.

Finally, I have not heard the Ethos but will hopefully get a chance to hear the Summit X in the next few days.

I am after speed, extension, holographic 3D soundstage with pinpoint placement of sounds/instruments/voices, refinement, low-level detail and resolution. Budget is 5K used. Does anyone have some advice? With the HT3's so far from the wall would that have distorted my impression of their imaging and image size? Are the Cremona M's in the same league as these other speakers or no? I am finding this very difficult.
