I agree, minimus, but a lot of people were blindsided by this recession/depression. A lot of discretionary spending came from home equity and seemingly secure jobs. Not everyone saw the trainwreck coming and were probably pulling out some money while thinking they were secure. So I don't entirely fault those who are selling stuff.
And, yeah, it is amazing what's out there right now. Deals that would have disappeared in hours are now lingering for weeks. I've picked up a handful of things lately for two reasons. First, the prices are good. Second, I think a lot of specialty gear is going to disappear over the next five years. Discretionary spending is gone. Lots of restaurants are disappearing and ominous signs all over. Audiogon, like you mentioned, is full of unsold gear at great prices. I collect fountain pens, and the convention I went to earlier this year had attendance over 50% off previous years. My family usually takes the kids to a dude ranch in the summers - it used to be hard to book reservations at the popular ones, but they've gone to nearly empty ranches the past two years. A cousin does amateur car racing. I usually go to the races and the attendance/participation is off by at least 50% from past years.
I've seen a few recessions, but this one is different. It's like someone turned off the tap.
The only audio companies that are going to survive will be ones with low overhead and a lot of flexibility. Audio might become not much more than a lot of cottage industries within a few years.
