berner99, glad to help. The point about speakers sounding good as one walks around the room is more a selling point than an absolute indicator of superb sound. Only IF you are up and about while listening regularly would that be important. It is certainly not a requirement to recreate a superb experience from the listening chair. Don’t be drawn off the goal by marketing and unusual features that do not necessarily mean the best experience.
I had the Apogee Caliper for a short period of time and it was meh, not terribly impressive. It didn’t help that the speaker had a surround issue and I learned why you don’t buy vintage from third parties when it involves shipping and you haven't heard the speakers. (Not condemning all third party vintage sales, just the one I experienced). But you couldn’t get me to go for an old Quad, Apogee, ML, or any of the others. WAY too good of new designs today, imo. YMMV
I think you’e answered the million dollar question, which would you prefer, panel like magnetic planar or electrostatic, OR open baffle dynamic? You likely would gravitate toward the open baffle dynamic. Now you only have to choose between Line Source or more defined arrays (such as 2xWoofer, full range, tweet) etc. There are several configurations, but I think you would lament the loss of dynamic drivers. It seems what you are gravitating toward.
