Very sad indeed at this news. I've known Paul via the phone for several years. I always looked forward to our conversations. We spoke about my Dude, audio in general, the care of our parents, fishing, and the latest news, sometimes for hours.
I believe if Paul had ever tried to go mainstream with his products like the Dude, Samsons, and his incredible tube amps he would be assured a place in the first tier of audio designers.
As it is, he's on my A list as an audiophile, inventor, and most of all friend.
R.I.P. Paul.
