Just my observation - seems like there is less listed on AG

Yes. I don’t know why but I myself is leaning toward to USAM as well. Maybe free listing?

I just sold 2 items on USAM, one of them 10 minutes after listing it, and the other in about one month. I don't see it as any less effective that Audiogon, and it's free.

I've been here since '98, and the difference is that it used to be mostly private parties, and you could speak to them on the phone. Now there are so many dealers trying to sell big ticket items to rich guys, and they can afford the expensive ads.

I stopped listing when AG years ago when they demanded a percentage, so I just checked what their current requirements are, but could not find it. That smells like they're afraid to post it!
