I think it's just you too.
I've owned the 2.1s for a couple years now. Greatest speakers I've ever owned. They've been turned on (powered up) 24/7 for over two years. No problems at all.
You SAY there have been hundreds of people with the same problem. Well with millions of units sold, that's a pretty damn good ratio.
The fact that Klipsch has been willing to replace your speakers multiple times goes a lot towards saying what a decent company they are.
