How to stop upgrading and aviod going bankrupt????

So I've built my system, and I love it. I don't want to get into the whole buy/sell/buy loop where I am constatly upgrading, and I certainly don't have the money to do so. But I am obsessed.

I love reading about high end audio, but it's not THAT satisfying. I can't keep running into my dealer's to hear things if I know I am not going to buy. It's not fair to him. And I keep hearing about new products coming out, and wonder if they are better than what I have. Maybe I should stop reading, but I enjoy it.

How do you deal with the upgrade bug?
