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?

Ledoux we sell neither of these loudspeakers 

Used to own Quad ESL 63 so the newer versions are still very similar.

The Quads all suffer from rolled off extreme top end and the bass response isn't that clean, a bit wooly.

The ML are the better overall design, the curved panel helps create a more focused soundstage and the bass response is far better.

You may also want to check out the Mura SP1 at $15k these are the best panel hybrid speakes we have ever heard.

@pvmike, Thanks for sharing you speaker placement info.  I would have thought that 4' and 1.5' from side and rear walls respectively were too close, not enough space to breathe.  But if professionals set up the speakers in your room with those final placement dimensions, then maybe my room size is possible to accommodate the 11a's. I do expect a fair amount of work getting the speakers to sound good as @hthaller mentioned, even with the final ARC adjustments. 

@audiotroy, thanks for your comments, I kind of understand your thoughts on the Quads. The rolled off highs and bass response were noticeable, although I wouln't  call the bass 'wooly'. 

It would seem that there are more nods to ML than Quads. I am definitely doing a second Quad audition just to make sure I agree.

Thanks so far to all your comments!

ML’s for me, I have the latest panel Monolith’s, and a friend has the Summits, they just do everything well, even hard rock.
They have a bigger sweet spot thanks to the curved panel.
More air around them the better, for sound staging, nothing in between them for as far back as you can get, this increases depth perception.

This setup is critical.:
From the central seated position in a darkened room, shine a torch from the top of your head at the panel, the reflection back should be half way up the esl panel and 1/3rd from the inner edge, for both speakers. Then prepare to be amazed, imaging even outside the speakers like you never thought possible.

Cheers George

Soundlabs are currently the best ESLs made and they will ship anywhere. Far superior to any ML or Quad and they will play loud and are extremely reliable. You do not have to audition them. Just read all the reviews.
