Based on above responses seems Dennis has tired of high involvement with audio. His new Inspire line is low key, sort of cottage industry product. He obviously sold his baby, Cary in order to get away from all the hassles involved with high end audio manufacturing. I can respect him not answering questions relevant to Cary products, no longer his concern.
Too bad for Cary owners, I had a number of interesting conversations with Dennis back in the day when I owned Cary amps. Also helped direct me in diy repair in regard to bias and cap issues with my amp. Dennis was a real gentleman!
