I think your reply answers itself. "A proper component setup". That is the right answer.
I have seen good components, poorly powered and they sound bad. Can't reproduce the details with the quality I look for. On the other hand, I have listened to mid tier quality speakers, sound very good.Placement is critical for the imaging, everything has to be balanced. But the best judge is the person's ears. Which many times has to do with their personal preferences for music.
