I agree with firearms as noted above. And especially if fired no more than moderately and well cared for. Some collectors just buy to collect and NEVER fire them, but I personally can't see doing that-- I want to know more about the firearm. Good firearms actually hold their valve much better than good stereo equipment. But I understand your point about "daily use"-- stereo equipment would excel there. Cheers. Craig
Other hobbies with these economics?
Audio seems to have an interesting set of economics for the consumer. Items depreciate substantially the minute they "drive off the lot", but remain just as "valuable" for many, many years in most cases. With proper care, these components retain basically 100% of their performance and usefulness, even with daily use. Compared to autos, computers, boats, etc., a well-cared-for used audio component is just as valuable, but much cheaper, than a new copy of the same thing.
Are there other hobbies where this relationship holds up?
