Audiogon is becoming the hub for scammers.

let say father is audiophile and his teenager son wants new iphone with beats headphones,he takes pictures with his android phone and sells his mcintosh gear,but ships nothing:)) I had similar experience when I wanted buy krell fbi amp,googled name of the seller and it appeared to be young guy abaut 15-17years old on facebook:))

on ebay a lot of scammers on other sites also

The INTERNET  has been,  IS,  and will always be the hub for scammers.

BUYER BEWARE!

"Let's be careful out there."

As a best practice, I always work to engage a seller in a substantive conversation about their gear, audio in general, what have you.  Scammers are not usually capable of holding that conversation in a way that doesn't raise red flags.

So by the time I've purchased something, I usually have a pretty good sense of who I am purchasing from, unless they are actually both audiophile and scammer, which isn't particularly common, I don't think.  Plus I've had some pretty enjoyable interactions.

It’s the responsibility of the manufacturer.
Before you allow your blood pressure to rise from my comment please allow me to explain.

When you purchase a Ferrari, either new or vintage, the owner is entered in a registry so every owner is verifiable. The registry also contains maintenance and provenance data. Enter the VIN on the registry and every single detail of the car appears. If the last address doesn’t meet or match the current owner then you can be suspicious.

Pass Labs does this, McIntosh I’m not sure.

I’ve bought/sold hundreds of items through this site and others over the past 20 years.. I have never, ever registered any of it with a manufacturer including probably 10 Pass items. Many of these items change hands multiple times.  It is NOT the responsibility of a manufacturer to keep track of every item they have ever sold. It is ridiculous to think that they would or even could.

Becoming lol. It have been for 10 years. One dealer has had the same pair of Wilson Sophia 3s (might I add spelled wrong) listed on here for at least 5 years. It has to be fraud. Paying for the same listing and never selling them or lowering the price? Get real.
