I think Onhwy61 makes a great point.
You seem happy with the sound. And, if you are interested in upgrading, I would ask what area(s) does it lie? From there, we can offer suggestions in terms of pushing your system in the desired direction. It seems as if your source, preamp/power amp, and speakers are on the smooth and warm side, while the cable is on the detailed and fast side. May just balance extremely well, and not need upgrading at all.
I can't argue with addressing the room, it's often the most overlooked link in the chain...
