One other thing I would like to add. His moniker on eBay is "Audio Deal Finder" ! What are the chances that he wouldn't have tested them fully ? IMHO Slim to None...

If audio is his business then you have to assume he would have tested them before selling to avoid letting those diamonds in the rough slip through his fingers for pennies on the dollar.Most members here have been watching Ebay & Craigslist,etc.. for a longtime.And can usually pick up these subtle things.
