As I posted over on DIYaudio I was lucky enough to work on a small project with Brad and met him for lunch to discuss. He was a gentleman, very funny and with electronics chops that were Jedi level. I wish life had allowed us to complete the project, but 2 kids arrived and things got a little hectic.
I have spent whole evenings just reading posts on various forums by Brad and learning a lot.
We are very lucky to have friends among us so willing to share.
