Every time I've auditioned Martin Logans, I've gone in and wanted to enjoy them...but I've come out with the impression that they are shrill...not polite at all, rather overbearing. Perhaps it was the setup or the amps (Macintosh solid state stuff, in both cases).
I certainly disagree strongly with Danielk141's assessment. I own ribbon-based speakers and have extensively auditioned electrostats. I have found Quads, Sound Labs and Innersound all to be at least as transparent in the midrange as any ribbon driver, and maybe a bit better with good setup and amplification.
Ribbons are probably the best at this time for treble.
