I think Howard Heiber got a great offer from Klipsch. Howard was getting on in years, and had acquired a big yacht, so he decided to take the money and retire.
Ian Paisley also retired around that time although he did stay for a while after Klipsch acquired API. I ran into him at a CES Show and asked him how things were going, and he told me he was weary of frequent travel to China. I think he left shortly after that.
