Your favorite Electrostatic, Panel spkr

I own ESL63s and have enjoyed them for about 5 years,  even in a "way too small - that will never work" bedroom converted to a listening room.  I thunk that room is even smaller than what you are describing. I drive them with an Innersound Electrostatic amplifier. 

For those who assert that Quads can't do bass, i can only say that when i got my new Supratek preamp the bass went way deeper. I now use them in a much larger listening room, and their sound has improved.

For your room and style of music, I believe the Maggie 1.7s or 1.7is with well integrated subs, would be incredible.
Over the years I've had many very nice speakers, but developed a particular fondness for stats and ribbons. For many years I had and very much enjoyed a pair of Quad ESL 63s. In my 14' x 26' with 10' ceiling, audio room, I now have the Maggie 1.7s with a very well integrated single ADS sub and the sound is amazing. With a bit of time and attention to set up, the little Maggies can present a very wide, deep, detailed and focused stage - both in and away from the sweet spot.  
I'm considering moving up to the larger 3.7i, or possibly the Sound Lab 645s,  but that would mean a need for more power and the 1.7s sound so very good driven by my 100W Rouge integrated tube, I'm not sure the gain would be worth the cost.
I can not imagine that you would be, in any way, dissatisfied with the Maggie 1.7s in your space.
There are a lot of good suggestions here for various other very good speakers, but If you do choose the little Maggies and would like some helpful suggestions on set up, feel free to PM me. The idea that ribbons and stats can not image out of the sweet spot is not true.......Jim

Jim, your Rouge integrated amp will have no trouble driving 645s to a reasonable level probably louder than the Maggies. However the 3.7i is an incredible speaker for the money. It is purely a financial decision. Either speaker will benefit from  subwoofers down the road. 

Mike,

I don't want to hijack the thread.   Yup, the panels are curved like the ML’s.    The total speaker height is 75-3/4” and the panels are approx 13” wide by 65-1/4” tall.

thanks.

Martin Logans make my ears bleed, Maggies otoh sound quite natural.
