Talk but not walk?

@hombre If you are interested in considering planars, I'd encourage you to expand your shopping list a bit and add Sound Lab, Sanders and Analysis Audio for audition. 
I am biased as a Sound Lab owner, but after having owned Quads and spent much time with many Maggies and listened a few times to the others, I think it would be worth your while. 
FWIW, I agree that in general you do need a pretty beefy amp with most of these guys. I am a bit surprised by @elizabeth 's comment that her 20.7s are easy to drive. Maybe they have been improved in this regard, but the 20.5 and 20.1s I'm more familiar with both benefit from plenty of power and current, and relatively suffer without them. I know Sound Lab has also gone to great lengths to make their newer models easier to drive than my vintage thirsty, hungry A3s. If budget is an issue, Sanders makes the Magnetech amps designed specifically for electrostatics, and they provide pretty great value/$ in that regard. Cheers,
Spencer

@hombre Yes, same Roger Sanders. 
Sound Labs, which are full ESLs (most models)' are also led by a Roger, Dr. Roger West. He's brilliant imho. Read his suggestions about how set up & room treatment should be approached when using his (and perhaps others) ESLS. Cheers,

@kosst_amojan Your last post says more about you than the person you are aiming your flamethrower at, in this case MG. His questions get right to the heart of the matter at hand, and you failed to answer. To generalize about the sound of all planars is pretty worthless. To say you don't like them and mention that you almost bought a pair is pretty worthless. 

To say, "They don't sound realistic and they have serious dispersion and room interaction issues." is worse than worthless, it's just plain wrong and does a disservice to the OP. My Sound Labs sound more realistic to me than dozens of other speakers I've owned(e.g. Nolas, Silverlines, Vandersteens, Thiels, Von Schweikerts, Avalons, Quads, Alons, Merlins to name a few) and hundreds more I've demoed.

When it comes to serious room dispersion and interaction issues, that varies widely by brand/model. Sure some are "head in a vice", like the old InnerSounds. But the Sound Labs have some of the best measured in room off-axis response you will find. Just a few days ago, a friend who does room acoustical analysis and treatment professionally was here measuring performance of the Sound Labs with his testing gear. He measured on and off-axis at 15, 30 & 45 degrees at 3ft, 5ft and listening position(12ft.) using his omni-mic and pc software. He told me that the off axis performance in room was better than most dynamic speakers and far superior to a pair of planar Apogee Stages + sub that he recently measured. Granted, this is in a treated room with a combo of bass traps, absorptive panels and diffusion set up in Live End/Dead End fashion as recommended by Dr. West at Sound Lab. Some of the results are attributable to the benefit of working on the room, but much of it is because Sound Labs and many other dipoles are less affected by side wall, floor and ceiling reflections than most other speakers. Granted, impact of the wall behind the speakers is great and the wall behind the listener does somewhat come into play. So you've got to attack the wall behind the planars with great amounts of absorption and ideally a bit of diffusion. That's a bit of my experience measuring and listening to planars. 
So instead of throwing shade at everyone, why don't you share what you've measured, what you actually listened to and what you learned from putting 2 + 2 together? That might actually help someone, including the OP. What I anticipate is a snarky reply belittling me or pretty much everyone. Please prove that assumption wrong. Cheers,
Spencer
