They're simply going where the money is, home theatricals. I believe the days of Cary developing any new hard-wired point-to-point amps (especially triode) is over. I'm guessing the 120S is a circuit board design & Dennis designed it before he retired, who knows? Enjoy the classics!
Why does Cary Audio keep discontinuing good amps?
Is this to keep us buying from them? Why not upgrade good designs?
