I have been slowly upgrading my system and as it has become more revealing, some questions have come to mind that I am hoping you guys can answer. I know that each time I upgrade a component in the system it becomes more revealing. And I also know that that means that recordings that previously sounded very good now sound great and recordings that sounded poor now sound poorer. What I'm trying to understand is does that mean that there becomes a point in upgrading where one should stop? In other words, if I am having trouble listening to CDs that I used to enjoy before because the system is now revealing many of their flaws, is that a signal that it's time to stop upgrading or even downgrade? I'm also curious if people become more able to become more tolerant of poor recordings over time after upgrading a system and there's just a period of adjustment. Or if upgrading means that the poor recordings now have to be adjusted using tone controls?
