New Demeter on-board...any thoughts?

I recently saw that Demeter has come out with a new bass speaker line and have also developed an on-board bass preamp. I've seen where several of the more popular high-end, small-production luthiers have been using this preamp and I was curious as to whether anyone owns a bass with this preamp or if you've played one with the preamp?

 

bump-surely someone knows something about this.
