Also, judgement alone might not be enough. Judgement can take you to "something is off", but not necessarily further. I mix music as a hobby and it takes a good amount of practice to step up from recognizing the presence of a problem to actually know where and how to fix it. If you don't know where you should look, you just aimlessly try various things, and it is not unusual to make the problem worse.

Eventually you learn to properly recognize the problems, not just their presence, but their actual nature and implications. But this takes practice.
