Has anyone noticed a slow down in sales?

Since I started in this hobby 20 years ago, I can’t think of many times when there WASN’T people belly-aching about the economy (with the other consistency being how peoples’ predictions are usually wrong!) or how the seller’s market is supposedly dwindling. The reality is that audiogon is losing business to alternative sites, one in particular. And they did this to themselves with the large increase in fees. You need to look around if your gear is sitting stagnant, and also ask yourself honestly if your price is reasonable. Some of you guys are asking for used gear what many people get for near or less NEW with discounts.

The problem with blue book, at least when I had it years ago, is it seemed to average the prices over all time. Unfortunately, the vast majority of components drop steadily in market value as their release date ages. And given the nature of our market, there often isn't nearly enough sales data for a single model in a relevant "last 3 months" window. So blue book prices were usually well above actual "market" prices. Maybe I'm misremembering that, or it's changed. Anyways, there is little use for it today when you can check hifishark for recent SOLD listings. That should be your starting point.
