What do you think your weakest component is? If not that, then what do you want to improve? Personally, I don't like your speakers. It doesn't really matter what I think, though. You're the one who has to listen to them.
I will say that your speakers and electronics are pretty well matched. It would be a good idea to focus on specifically what you want to improve. If you upgrade something without being sure, you can easily make a mistake.
