Your favorite Electrostatic, Panel spkr

Quad ESL 57 has a tone that entrances me.

Well audiokinesis we have something in common. I do not have my 845s yet but they are for certain my next and probably last loudspeaker. 
douglas_schroeder, what did you think of the 545s? I'm not sure but I do not think we can get KingSound speakers in the US. I went to their web site which is a bit crude. Their speakers are listed as having cross overs at various frequencies usually 1200 Hz. Not sure what the reasoning behind that would be.
Willieva, you bet. The 4s had the best bass because they had the largest baffle area. The 2+2s are narrow with very little baffle effect. They don't really rock until you use them with subwoofers.  I used subwoofers with Monitor 4s. I took them off those cheesy plastic stands and plopped them down on RH Labs subs and boy did that rock. Those Stasis Amps were something back then. 
bdp24, it looked to me like you were saying the ET was an ESL. I do think ribbon tweeters are the best made primarily because of their very even figure 8 dispersion characteristic. ESLs beam which causes the manufacturers to do all sorts of crazy thing like making you sit in one chair to curving the panels making them non linear. I do think Acoustat and Soundlabs have the best solution by angling narrow flat panels to cover a wider area. The Acoustat 4+4 and the Soundlabs 845 are very similar speakers the Soundlabs being more modern is certainly more sophisticated 

So.......my room is 9.5’x12.5’,8’ceilings

would these be going on the long wall ?
the A-3’s in my room would be HUGE:0)

as of now budget is up in the air, this is a retirement present to myself, i dont think $3,000 is off the mark for speakers, so a grand above and below would be my variable.

I currently own Quad ESL 57, Acoustat Model 2 (modified and used with the Acoustat Direct Drive amps), and just picked up a pair of Analysis Audio Epsilon (planar ribbon). There is no substitute for the mid-range in the 57 in my opinion. The Acoustat's and Analysis Audio provide great mid-range as well, but the Quad are not to be outdone in that area. Although the Quad do not have the extension at the extremes of either of the other speakers, I find the bass satisfying enough for my tastes. That being said I ended up bi-amping with an electronic crossover and adding a multiple sub array to my system so none of the speakers drives anything below 100 Hz.

@kgveteran you mentioned two different room sizes in your posts, neither very large. Here are a couple thoughts. The Magnepan LRS comes in easily under your budget, and some of the larger Magnepan speakers are going to fit in your budget as well. If you buy the LRS direct from the factory I believe there is a 30 day trial so you can try before you buy. Another option is the JansZen Carmelita hybrid ESL monitors. Nice foot print but a tad over your budget. JansZen offers a trial period as well. Either of these speakers can be used on the short wall if you prefer. With the Maggies you would have enough money left over to add a couple nice subs and still not compromise your space.

Well, with kgveteran's latest update I suggest that a bigger magnetic planar or  ESL would be problematic. Imo both the King III and Sound Lab, as well as the Eminent Technology are eliminated. You would do far better with a dynamic speaker imo than a larger panel in such a close space. 

mijostyn, I would rather not discuss extensively and rewrite the book so to speak. The King III and the Ultimate 545 are a study in contrasts on several levels. You will get a very thorough introduction to either speaker by reading the reviews, including the highlights and caveats. Twin Audio Video is listed on the King's Audio website as U.S. Distributor.
