Full range electrostatic speakers have their own set of attributes, weather they are for you I cant tell you.
Having owned a few stats, my Sound Lab A3's had the best dynamics and bass of the bunch, their soundstage presentation is full and wide but do not have the image localization abilities of some planar magnetic/ribbon speakers I have had. This is not a bad thing ,they sound more like the presentation you hear in a concert hall. An analogy I would use is the difference between a focused beam of a light as opposed to a fluorescent bulb that bathes the area in light. Stat's in general have very low driver distortion ,this is achieved by push pull operation and very little diaphragm movement,, hence the need for the panels to be large to put enough sound into the room. They also require the proper amplifier to perform at their best. I had 200watt mono OTL tube amps. OTL's and stats are a great match.
The first time I heard big Sound Lab stat's and a big OTL amps I was floored by the huge natural and powerful presentation they offered.
Placement and room acoustics can be tricky with large stats., I found they were not the easiest speaker to get good bass from, not that they are not capable of good bass, just the placement and room acoustics are very critical.
The down side is their size ,price, amp requirements, and reliability. I am sure they have gotten better, but I had an older set of A3's and the coating on the diaphragm had to be redone twice,,when it went a third time that's when I moved on to another speaker.
As far as which model, I guess that depends on how large your room is and how deep your pockets are.
I know there are not too many places to hear Sound Labs, but if you find a place ..it's wroth the trip.
