I don't mind telling people what my expensive stuff costs if I know they can afford it. Sometimes that leads to an interesting discussion. But I don't like telling them if I know they can't afford it, but that likely makes a lot of people feel worse about their financial situation.
There's a threshold aspect to this too. If someone can afford to buy just about all of the things they really want, the fact that some people are much richer than them may not really bother them. I put myself in this category - I'm glad that I can buy whatever headphones I want, but I don't feel deprived that I shouldn't really be shopping for private jets and sizable yachts. With the right perspective and discipline, there can be a point where you feel you have enough, and don't need to keep wanting more.
All of this said, I predict that I'll wind up buying the Empyrean at some point, based on the reviews so far and how much I like the 99 Classics. I guess I do have some degree of addiction ...
Addiction is part of human nature for better or worse. My addiction to organisation and cleanliness can be considered both a good and bad thing depending on your perspective lol...
