Stellar CM-6...Anyone use it?

I just heard about the Stellar CM-6 tube based large diaphragm condenser. Has anyone here used one?

Here’s a review vs. the CM-4 and the Neumann TLM103, which I own. I must admit that I’m impressed especially considering the CM-6 costs less than half that of the Neumann.

Any thoughts, especially from those who have used it?
