Usher BE-10?

Hi, has anyone heard these speakers? How would you characterize them? Are they warm, revealing, bright, aggressive, laid back, dark, etc. They look great and the beryllium tweeter and mid seem very interesting! Thanks in advance.
Yesterday i heard them for the first time.
I know the Usher AC 10 well, the be 10 has a larger woofer, and a high en mid beryllium driver.
What i have heard the are very revealing in a very natural way. I've heard them with a classe omega amplifier, not my first choice, i prefer a tube.

Not cheap but beatiful made.
