PWK never lost his passion for audio. He could talk your ear off with information about all things audio. HDBR nailed it! From 1989 on, the company was no longer his, he had retired.
PWK had strong opinions on certain things. If you wanted to change his mind on something, you had to prove it! No one ever proved to him that "front mounting" really had that many benefits. Remember, he had to balance production factors with everything else.
