I had not heard this until you let me know and MJ also just mentioned it. I meant to acknowledge that in my response to you but forgot. I had hoped to meet Rupert at AES in NYC some day, which I occasionally attend. I had slated to go last October, but it was online only due to Covid. I have met and enjoyed conversations with other audio luminaries there, such as Ray Dolby. It is very sad, though at least, at 94, he had a decent run and accomplished much.
