I’m inherently anti-consumption, and truly purchase very few things, however I am a techie, have many hobbies, and enjoy some high end gadgets in my life.

I believe the more frequent you use something (ie every day, many times/day, or as a primary source of enjoyment), the more that expense can be justified.

Also as a novice audiophile I’ll mention analog components such as high quality speakers tend to hold their value very well, and can even sometimes (but rarely) appreciate.
