Well, face it. Your a hobbyist. We hobbiest are never satisfied. There is always the 'bug to tinker' : )
While I don't know your equipment (except that it is very good by reputation) May I suggest some relatively inexpensive tweaks: cabling as suggested is obvious but might cost a bit more than you want to spend. On the other hand you can audition cable (www.fatwyre.com) at little or no cost and evaluate the changes in your system. Sometimes after tryign different cable you find that your system is fine unchanged and the upgrade bug is fed (for a while). Another area to explore: room tweaks. Joh Risch has written a lot about simple inexpensive tube traps which can be fun to make and highly effective. This also feeds the bug. You didn't mention anything about your equipment rack but it's amazing what resonance control of electical components can do for your system. This applies to CD players of course but even amplifiers benefit. This is the nice thing about our hobby; you can spend big or you can spend small and still have fun making audible improvements. So have fun!
