Early this morning I learned that my mentor, one of my best friends and the most brilliant, generous and coolest guys I've ever met, David Graebener passed.

He got me into this business (He founded Speakerlab), then did several projects for a few other companies (Bohlender Graebener & recently was the chief speaker guru for Wisdom Audio).

He pioneered and perfected ribbon speaker technology. He was never satisfied, always striving to make his stuff "a little better".

We shared some amazing experiences over the years. The audio world lost a true genius, and one of the most amazing individuals out there.

He was a true free spirit, and a true hippy to the very end. He never gave in to being a three piece suit kind of guy. He was always just David... A cool long hair who held onto a lot of values and qualities he developed back in the sixties, growing up.

May he rest in peace.
