Any one heard of Audio Matsere?

I think the company is long out of business but I am looking for information on their tube power amps. Any information would be appreciated.

Thanks and Happy Listening.
I beleive it's Audio Matiere. It's a French company and I think it might have morphed into another company but I'm not sure. Others may know. Good luck!
Audio Matiere is now Audio Aero. Their amplifiers were a very good bargain.
