I frequent Head-Fi too, and occasionally I get the itch to get a new pair of headphones, but I've figured out that in order to get a significant increase in enjoyment out of my system, it would take more money than I'm willing to spend on headphones now. And I really am very satisfied with what I have now.

I'll only check out a pair of headphones now if they're of the "incredible bang-for-the-buck" variety. All the "boy do I want that!" money is reserved for photography now.
