When I was young I did save, save, save and go to retailers to listen, listen, listen. There wasn't as much of a used market because there was no internet. I don't remember ever seeing any desirable equipment in the newspaper classifieds. When I could, I bought some demo units. Reached a point where I was satisfied and then the kids took over my attention.
Things are much more fun now. You can get reliable opinions on a lot of quality used gear and get some real value. Unfortunately, I can't listen to much at retailers anymore. There seems to be nothing between the big box stores and ultra high-end in my area. Three of the high end audio dealers are great places run by great people who will help you put together a nice system at a reasonable cost. It's just that they don't have any tower speakers or pre-amps below $2,000 each on the floor. They'll be happy to order it for you; but you don't get to compare. So I guess, as Joni Mitchell said, something's lost but something's gained.
Either way, I;m much more obsessed now then I was 30 years ago!
