Leedh E2 Glass is the latest version as reviewed on 6 moons - http://www.6moons.com/audioreviews2/leedh/1.html. They achieved the 6Moons Blue Moon award: Quotes:
"The Leedh E2 Glass delivered outstanding clarity and first-in-class soundstaging with high dynamics and stunning linearity. The most impressive improvement over the previous carbon diaphragms or even the Munich prototype hybrid was even higher transparency. The E2 Glass delivered such a flow of tones and harmonics that I had the uncanny sensation of having suddenly added complete very sophisticated tube amplification. They provided a supremely liquid result in the same style of my best experience with Kondo electronics associated with ultra-expensive speakers like the Living Voice Vox Olympian. The main difference with that cost-no-object system, in my opinion, was the superior soundstage of the Leedh which was more stable, defined and focused."
"If there was a pantheon or other celestial gathering place for all-time greats of loudspeaker designs, the Leedh E2 Glass would naturally have a privileged seat next to the MBL 101 Extreme, Apogee Full Range, Magico M Project, Living Voice Vox Olympian and Vivid Audio G1. But it is not simply an amazing feat of engineering. It is also a fantastically emotional and dazzling vehicle." You will see that they are tiny - unusual looking - but huge in their soundstage. This pair is a few months old only, directly purchased from Leedh Audio in France.
