Speakers with the most detailed midrange? (non-ESL/planar)

I'm a fan of the Classic Audio Loudspeakers (+$12K).
They employ a beryllium diaphragm that has a Kapton surround- and thus the midrange driver has no breakups until 35Khz. It runs from 500Hz in my speakers to 12KHz. The driver is also field-coil powered so it has speed like an ESL, and for the same reason- when current is applied to the voice coil, the magnetic field does not respond in kind by getting weaker as in permanent magnets. So its faster and more revealing, while at the same time very smooth since there are no breakups.
The larger Classic Audio Loudspeaker (T1) has the midrange horn going down to 250Hz. This is possible due to the Kapton surround.

I bought Thiel CS2.4SEs about a year ago because I wanted greater transparency and resolution in the midrange. Wasn’t disappointed other than a subtle glassy quality on vocals. Replacing the resistors with Mills MRA-12s fixed that issue. More recently, I rebuilt the boards with Clarity CSA caps and upgraded the coils. 

Now, the resolution and transparency are stunning. There is superb intelligibility on lyrics and much more. Gotta be close to SOTA from the mid bass up but I suppose I need to relisten to stuff like TAD Ref Ones and Vivid Giya to say with full confidence. Regardless, these are my last speakers!

The Kithara $6,000Read the all new review of the Oskar Heil Kitharas by the legendary Wayne Donnelly at enjoythemusic.com under the "Superior Audio" section of the site.Here's a link<This link's target cannot be found>
"The Kitharas recreate the performing space — especially on naturally mic'ed recordings — extremely well. Specific vocal and instrumental images are stably located within a nicely dimensional sound field, but without the laser-beam imaging precision and hyper-detail retrieval that are characteristic of imaging “champs” such as the Wilson WATT/Puppy and ambitious minimonitors. As someone who attends dozens of live concerts every year, I can testify that listening to the Kitharas is much closer to what I hear in the concert hall than with most audio systems, even those with much more expensive loudspeaker systems""The Kitharas are real right brain loudspeakers — as emotionally seductive as any loudspeaker I have heard. And in that sense they are, as declared in the title of this article, greater than the sum of their parts."
