I noticed the same thing, and started a thread regarding this, but Audiogon wouldn't post it. I do think that this used to be a smaller, tight knit community then it is now. These kinds of bogus ads were found on eBay, but never here. Unfortunately, it's now a case of buyer beware.
What's up with ads for $70,000 speakers selling
for $5,500? Martin Coltrane for $5,500, Wilson Max ll for $6,500 two days ago. The sellers are from Europe with zero feedback. This is becoming the norm and I am disappointed with this trend of dishonest sellers permeating this site.
