Your gear sounds pretty well tuned from your description. The next step up may well come at some cost.
So, as long as this is the case, buying anything is taking a chance. You might like it or you might not. Maybe you don't want to risk this if the next step is very costly.
For my 2 cents, then, you need to meet other audiophiles near you and get acquainted with their systems. If you post where you live, maybe someone can help you contact a club, for example.
There's no lack of good stuff to try, but it's the combinations that make the magic. (That, and room treatments. If you don't know which way to go but must do something, treat your room.)
I have never really heard any high end gear so I don't know how mine stacks up.
