To me, the most interesting thing about systems is that they all sound different. I try to identify the difference, before I make any judgement regarding the overall sound. Recently I listened to the big (and beautiful) Italian floorstanders at my friend's place. When I came home, listening to my own system, I first became sad and disappointed. His system sounded better. Especially, the treble was clearer. But then, I listened some more to my own system, noting that it has strengths compared to my friend's system. The treble may not be as sharply defined, yet the music sounds very embodied, even muscular (when called for), with a very lively and engaging 3d soundfield. So even though the Italians were hard to beat in some ways, other aspects pointed other ways. There are plusses and minuses with both system. This made me relax and enjoy what I have, and listening to other systems as well. It is a good idea to start with the plus points, rather than focus narrowly on the problem areas, e g a not-quite-optimal tweeter solution.
