I think this is a fair statement. Feel free to disagree if you are inclined. Though many people like Eidolons with tubes, I think they excel with coherent and fast solid state, where the Eidolon transparency, staging, and resolution really shine. They are holographic in the sense that electrostatics are, and in that sense they are thinner than a traditional tube presentation is, though in every sense musical. I simply disagree about coherency, having heard Eidolons with Spectral's best amps and latest DMC-30sl preamp and with excellent room acoustics and vibration control. The stage is tightly coherent, wide and deep. Eidolons mirror the signal fed to them.
On the other hand, if you prefer a warmer, fuller tubelike presentation, then Kharmas appear to be well-matched to electronics of that type. My impression of the $70k Exquisites with Lamm is that they portray, say, a guitar in the same room with you in a more vibrant, organic way than Eidolons, while Eidolons will excel in portraying realistic soundstages with fine low level detail.
I haven't heard the midi-Grand or Ceramiques, but there is probably a family resemblance.
Basically, I'm suggesting there is a style difference in the two speaker lines which would probably be revealed by a/b'ing with similar electronics.
