Just heard from PS Audio that Arnie Nudell died from complications associated with pneumonia. Mostly associated with Infinity speakers, Arnie was involved with the development of the latest PS Audio power amps, the marvelous BHK series, and you can find a few comments from him in the associated videos put out by PS Audio at the launch, which give you a flavor of the man. He was 80, lived a life, and contributed to the art and science of music reproduction. It was rumored he had a new speaker in the works too. RIP Arnie.
