I'd take a hiatus, then get something really great. One thing I've always thought is we're never satisfied, because we usually make incremental improvements. If we could get the ultimate system all at once, taking one giant leap, it would (hopefully) be overwhelming. So take a few months, maybe borrow a boom box, then when you put your system back together, you will appreciate it all the more.
Familiarity breads contempt.
Absence makes the heart grow fonder.
Or maybe you'll discover you're happier with a cheapo system, and focus on the music not the system.
