YES.
1. Amateur astronomy. Purist telescopes with frequent upgrades & tweaks for improved performance. Incidentally, a lot of apochromatic telescope purists are also audiophiles. The philosophies are highly congruous.
2. I have a wife that likes to upgrade herself with a lot of (tasteful) plastic surgery... and I end up losing a lot of money on that too but absolutely love it-- so worth it!
3. I like high-end cars made for comfort and elegance, especially those made in the UK.
4. I am fascinated by high-end anything! Its so wonderful to see the state of the art in just about any field!
5. I enjoy science, and especially enjoy the nonsensical, as-of-yet inexplicable forefront of new learning.
6. Purist organic and live soil grown foods. Food tastes better when it is as nature intended it! Factory processing is not as good! A lot of audiophile similarities there too.
Great topic! I've enjoyed reading other audiophile's answers!
