Personally, I believe your playback is as strong as the weakest link. There is no perfect equipment . . . otherwise, there would come a time when no improvements and the industry would come to a point where their “new models” would cease. Think about it, this is never going to happen, because it would be like all disease and aging were eliminated -- how many medical and pharmaceutical companies would go out of business? You do not cut off your nose to spite your face . . . at least not among the wise and intelligent.
Let's face it, the tweaking and the updating is part of the charm and frustration of the hobby. Without it, hobbyists would have to seek another hobby to satisfy that endeavor. Contentment, as is the case with those with LIMITED wallets, would have to become a mental acceptance that there is no more updates or improvements to be had . . . perhaps all that would be left to do would be to replace that which would wear out or got damaged.
