fake opa627's in the wild. - Page 12

Anybody here bought the OPA627AP with Class A Biasing Mod from tamaudio? http://coolfungadget.com/store/index.php?route=product/product&product_id=91

I mentioned in another hi-fi forum that I purchased the above linked opamps and several users suppose they're chinese fakes. Anybody can apply for this? So if yes how big is the sq loss in comparison to the genuine?

This are the OPA627AP that I got form Element14 formally known as Farnell 

I bought 2 and soldered it onto an adaptor 

Can anyone tell me if it is real or fake ?

i think the name of the company itself is already giving a reliable warranty for the product they're selling. i bought tons of stuffs from farnell and i can say none of them are fakes

I've never had a fake from Farnells, very reliable company

With all the fakes on eBay, is it worth trying to sell any of these op amps there? I'm trying to clean out my basement but I'm kind of sketched out that everyone else posting auctions there are based in China.

Does anyone here still buy these items off eBay?

Were they fake then from tamaudio?

I sold hundreds of the 627AP opamps nobody complained about the genuineness.
