I'm thinking of dabbling in the Norh 9 speaker for fun. Does anyone have experience with this speaker?

The concept is intriguing. It's shape is based on an African drum, is made of solid marble and has great drivers. Good reviews too, but it would be nice to here if someone has heard these speakers in action.
