Upgrading doesn't satisfy everyone either, check out some of the ARC threads. There are a great deal of ARC owners that are miffed because ARC continues to upgrade their designs more than other companies. Let's face it, technology is changing very rapidly and companies need revenue to survive, just the way it is! I am okay with it as long as they continue to service the obsolete component.
Why does Cary Audio keep discontinuing good amps?
Is this to keep us buying from them? Why not upgrade good designs?
