What would you do?

I'm still waiting to read about whom you think the culprit is?
It could be worded as to imply this might be happening.
Too bad you had such a bad experience in audio, most out there are honest, but one does need to be careful more fraud than ever going on.

Audiogon does auctions where audio manufacturers sell equipment? I didn't know that. I thought it was all person to person/ used stuff here..

So to be clear I'm not talking about auctions on this website. This is on another auction site that is, uhm, pretty well known. And the products in question I guess you would call 'audio accessories' although they do make speakers.

Post twice that will help?

Zu Audio?

It's time to put your big boy pants on and reveal the swine! Otherwise the accusations you make bare no fruit! It's time to get yourself a pair of balls!
