Spend a lot of time working on set up and treatment of your room (even if you think you have done this - revisit it). You might be amazed at the differences small changes can make - often much greater than buying new stuff. For example, in my room, which I thought was well dialed in, I moved one speaker closer 1 1/2 inches and the other 2' further to toward the outside (no longer symetrical) and the sound stage clicked in like I couldn't believe! The first time I have ever had great layered depth of imaging in my present room.
Re new stuff, what kind of sound are you looking for - what about your present set up do you not like? Give us a clue and I'm sure you'll get some meaningful recommendations.
