The first part of your post references what I was saying about the difference between being able to detect a difference whilst straining to do so, and just listening for pleasure at home. Indeed if the difference is so minute that one has to learn to listen and even then can't detect it, as many (most?) can't, then I suggest it's insignificant. As for your last sentence I would ask, is that regardless of current amp or budget?
