Quad 2912 vs Martin Logan ESL 11a

I am seriously considering electrostatic speakers although living in a part of the world where dealership for both brands do not have all models on hand for audition. While the 2912's were unavailable, a Quad 2812 was available a month ago for audition. It was in an all Quad setup, with a solid state and a 40  watts tube amp for comparison. In a 4 x 4m room, the music was very engaging playing Miles, Coltrane, and Heifetz. Transparency and speed were plenty evident, and  there was a warmth and solidity ( coherence ?) that was a pleasant surprise.  

Last weekend,  audition of  the Martin Logan's esl X was arranged . This is a few step down from the 11a's. Although it was in a totally different system, the ML seemed to be of a different sound signature. Brighter, more air? Ultimately I was not  impressed with the X's, the woofer seemed not to integrate well with the panels. And the salesperson admitted as mush. He said an audition could be arranged in a week or two for the 11a. 

While I wait for a proper audition of the ML 11a,  I would appreciate any comment specific to these two speaker models. Not all electrostatic speakers are created equal, as I have found out.   If the choice came down to the two, what are the issues that needs to be considered?

@ mijostyn, I had done some research on Sound Lab.  Given my situation with lower power tube amps, unavailibily of  dealer support, and frankly, pricing that is out of my range, there is close to zero possibility of my owning a pair of Sound Lab speakers. I must confess a sense of envy when a recommendation for a pair of speaker would include, '.. You do not have to audition them..". They must be amazing! Alas, not for me.

Hi George, Thanks for the straight up recommendation. Monolith is one of the very early ML to come out. And  it seems that are many loyal fans of the speakers with active crossover and the possibility of bi-amping. 

One of my concerns is the maintenance of the Mylar panels. But it seems that committed users treat it precisely as a maintenance issue to be dealt with rather than a nuisance.

Been devoted to the sound of planar speaker designs beginning in the 70's, and have lived with various models from Magnepan, Acoustat and Martin Logan over the past 40 years.

I've owned the 11A for two years at this point, and have been quite happy with them. An amplifier that can reveal their best potential is key. The huge sound stage, well-integrated bass response, open and clear mids, detailed but smooth top end, that these have always been capable of are presented to great effect with the Carver Crimson 275 (which provides plenty of power given the speakers utilize their own woofer amplifiers).

Using the same all-tube front end, had also tried a couple of well-reviewed class-D designs plus a Rogue Stereo 100; each sounded quite nice, but it did not take long at all to appreciate the Carver's elevated performance once installed in my setup.

I own the previous model, ML Montis, also with 11 inch panels.  I am very happy with the sound.  When I was auditioning, I was very much unimpressed with MLs lower end offerings.  Would love at some point to get the 13a's.

  One of my concerns is the maintenance of the Mylar panels.

This goes for any ESL's
No problems, depends how you treat them, by doing below you'll get an easy 10+ years out of the panels.
  
Don't smoke any kind of stuff in the same room
No direct sunlight on them, or have them in a damp basement. 
Don't have dust all over the place, or dog/cat hair  
Vacuum panels once a month, front and rear
Don't leave them powered 24/7, switch them on 1/2hr before listening.

Cheers George

@georgehifi  Of the five points to 10+ years of maintenance-free ESL usage, I can fulfill all the requirements except one, dampness. With the rainy season  upon us in my part of the world, it's a constant 70%-80% humidity level. In fact it kind of hovers around that level pretty much three quarters of the year. Dehumidifiers are a must in the listening room. I need to reconcile seriously a dehumidifier blowing pretty much constantly in the room. 
Thank you for the maintenance advice.

I wonder also if my 40 watt Von Gaylord tube amp is adequate to drive the 11's. The 11's having powered woofers are less of an issue?
