Before A'Gon there was a monthly newspaper called "Audio Trader" or some such. Or you could look in your local newspaper!
Do you remember when Audiogon was just a bulletin board classified ad site?
I wonder if anyone else remembers Audiogon from 15+ years ago. I remember visiting the site daily scrolling through all the listings. Back then posting was free and you had an endless number of ads. It had as many used audio listings as Ebay. I can remember buying a Paradigm CC-200 and also a pair of Paradigm ADP-150's back around 1999. Those were my first two purchases. How about you?
