Just remember that, once started, upgrading never ends. When you get something new, it is wonderful and really enjoyable, for a while. Eventually, you start wanting something else. My conclusion is that it is really newness itself that we are after, rather than "better". (Everyone loves that "new car smell".)
I try to make myself spend my $ on music and movies instead, but I know it is just a matter of time before the upgrade bug strikes again.
FWIW, I am not a fan of Klipsch Synergy. I think you can do better at the price. (Check out Athena AS series, Infinity Primus, or the ID brands for starters.)
