What's up with ads for $70,000 speakers selling

I agree with most of what has been said above, but when it comes to high ticket speakers, moreso than preamplifiers and amplifiers, there does seem to be a very substantial drop in value after they have been "driven off the lot".
I remember even very recently seeing an Audiogon retailer trying to sell a pair of Nearfield Pipedreams for a small fraction of their original cost. As I say, I notice it more with components, especially speakers, that had original prices that were stratospheric.
As I remember, that retailer has been trying to sell those pipedreamss for a long time.
Another reason I believe is that some brands don't get enough press, and their name recognition when it comes time to sell is very low. Good example: Stealth Acoustics.

I contacted each seller and spoke with them. I purchased both speakers and used a local dealer in that country to verify them and ship them to me for a fee. I am enjoying them both now and will probably sell one pair off when I decide on which one to keep. Don't look for me to sell them that cheap though! Both sellers had lost their jobs and needed money fast! The fish was the biggest I ever caught also!

Happy Listening.

LOL! Bill, c'mon, you shouldn't need AudiogoN to point out such an obvious scam. In case you missed the memo, Audiogon has changed. There's no turning back now...full speed ahead (reverse?).

Not just Audiogon. I had my E-bay A/C taken over by changing the password and about $1000,000 of stuff put on with a 3 day sale, speakers, Audi', BMW's. I was around and told E-bay. Obviously looking for folks who don't check their A/C frequently.

In the strongest possible terms, I recommend exercising extreme caution.

Not sure if anyone remembers, but several months ago a seemingly authentic looking/appearing e-mail went out asking members to verify their accounts. I happen to know the fallout of that left some accounts hijacked. Soon afterward, classifieds popped up offering noticeably attractive (though not too good to be true) deals from sellers with strong feedback ratings, and though you could tell the member was obviously based in the USA, the sellers were always overseas - usually Eastern Europe.
