RE: Are cheap Hong Kong sourced opamps real?

I have now received new OPA2107APs from Mouser. First off, they are a cosmetic match for the first units I bought over a year ago from legit distribution, and look nothing like the parts I got recently from ebay. This alone might not mean anything, but I made some pin-to-pin DC resistance measurements as a basic check between the two types, and they are clearly different. I have yet to do my listening tests, but I am now fairly convinced that the parts from ebay are indeed counterfeit.

Best regards,
