However, the audio hobbyist (this does not include most buy-and-hold stereo owners) is no different than an automobile or model train enthusiast...constantly tweaking and improving the object of desire. :)

Can't agree more. We even can take this statement to the next level. If everyone would hold on to their equipment forever, people like John Bowers, Richard Vandersteen and thousands of other researchers could retire and keep making money by building same design forever.
To build your own system is same thing since it consists of various components. People change components to find sound that they looking for of to experience something new. But it's not for everyone. Not everyone has time for it or passion towards the same hobby that would last forever. For some it's until they find the sound that they can live with for the rest of their lives, for some it's a hobby, and some like to be informed about technological progress and constantly try something new.
The answer to original question is yes; because my love for music is greater then love for money. If I had to I would pay for it full price and still be in this hobby. My system would not sound as good as it is now and I would take small steps to improve it. So far I didn't pay full retail cause I'm a student.
