The man was not just a celebrity and a legend as I discovered in 2018 when I went to a demo and talk by him. He was a friendly guy who was very articulate and fun communicator. He explained succinctly explained how we never get imaging and stereo with headphones due to the speed at which the two speaker channels reach our ears in a way that made a lightbulb flash over my head. He told us all a short history of CD as well. RIP Ken was a pleasure and a privilege to have met you.
