Vintage hi-fi, like many collecting and preservation hobbies, is subject to the '30-year rule'. This states that today's top collectables are those products that were new about 30 years ago. The reasoning is that when you are young you covet certain items as objects of desire, yet lack the means to buy them. As life progresses, you (hopefully) become wealthier and look again at what it was that caught your imagination when young.
