Based on my experience here in Phoenix & watching the web,
I'd say you've probably noticed what one of my local dealers calls "flavor of the month" syndrome. A speaker or other component will get a rave review in one or two of the high end magazines. Many audiophiles will look locally & on the web for the item, buy it used & live with it until the next "latest & greatest" comes along. If the ads had the serial # posted, you could watch some items change hands several times. Even if the component is very good & the best example of that specific component some audiophile has owned, some people will roll the dice & sell what they've got to buy something they've only read about...
