I just has my first child (well, my wife did actually...) less than 3 months ago, so I can tell you the speakers excitement is nowhere near as intense.
I moved from a pair of Paradigm Monitor 9s to Axiom M22s and an SVS PB1-ISD sub. I've had them for almost a year and I have not once had upgrade-itis. I might have had what-if-itis once or twice, but I have never regretted my audio system decisions for a second.
My advice to you is to fall in love with your speakers. It'll be that much harder to break up with them.
