You take time off work, and may travel a considerable distance (100k in my case, don't laugh but UK is not the US) to get to listen to pair of speakers that you know must be great. They were designed by a legend in the industry, they've been reviewed well in the press and the dealer is a very nice guy. You really want to like them and they should sound great but they don't because you can hear slight but definite coarseness where the tweeter crosses over to the bass. So disappointment follows.
As you said, if you were a newbie you might not hear it if you've abandoned a critical mindset. Then you've either got to do the return journey or put up with the issue. You could even try tweaking and waste more time and money. Whichever path you pursue more disappointment will surely follow you.
I imagine that for most people audio is but one way to pursue relaxation (sometimes stimulation). Stress free as far as possible. As much fun as possible. And for me as much tonal density as possible!
At some point we want to stop chasing magic and get off the roundabout to smell the flowers. Hi-Fi can be like a marriage, enjoy what you have but it doesn't mean you aren't allowed to look occasionally!
