Well, it seems that the demo room is getting in the way one way or another. I mentioned the Triton 1's because they are one of the few speakers that 1) fit your budget and 2) have the frequency extension, dispersion pattern, and bass power to energize a room the size of your listening area.
One of the problems auditioning GoldenEars is that because they're less money and distributed along the lines of Polk and DefTech, they often get paired with mid-fi receivers instead of high end separates that they deserve. Because the Triton 1's have a self-powered bass section, they can get by with a lower powered main amp, but it needs to be a good one. Maybe your demo was powered by Parasound, but I guess we don't know for sure.
Also, on a short listen, the Tritons (or any of the GoldenEars) can sound "polite" because of the folded ribbon tweeter. More extended listening will reveal that all the treble, overtones, and air are there, but minus the overshoot, ringing, and harshness that often accompanies pistonic tweeters. The Motion Transformer tweeter has several square inches of radiating area, so it requires very little movement to make lots of sound. I think we're so used to hearing treble harshness that truly smooth tweeters sound sort of dull until you sort through the sound. Just MHO and may not apply to your audition.
The Cremona Ms rang my bell Iistening to some Diana Krall backed by Christian McBride on bass and Russell Malone on guitar. It gave me everything--clear in-room midrange, articulate and linear bass on McBride's bass lines, and seductive hall ambience. The biggest surprise, however, is that it was being powered by a $999 Marantz integrated amp, the PM8004, since superseded by the PM8005 at $1199. That 80 wpc amp was fast, clean, organic, and maintained an iron grip on the bass.
From what I've heard, the Cremona M is strong down to 40Hz, which covers most music, but drops off from there, and some like to add a sub to cover that last octave. with the Krall trio, they didn't need anything. The Cremona Ms also satisfy your desire for soundstage *and* imaging. A very fine speaker. Although they're not panels, they have big outriggers and are deep, so they need a bit of space too.
In my experience, the Maggies' panels don't block the sound, they're *making* the sound, and properly set up they throw a seamless soundstage with lots of 3D imaging. 3D imaging depends in part on everything being in phase, and it helps that all a Magneplanar's sound is emanating from a flat panel made of one material, so all the primary sound hits you at the same time and of a piece. You don't have woofers, mids, and tweets made of different materials, of different depths, and different risetimes trying to make cohesive music. The Maggies have that advantage.
