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?

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?

Hello,
 
i recently received some OPA 627 APs. Does someone know if these are legit?  This is what they look like:

 
I would be very grateful, if you did let me know what you think about these opa627. Thanks!

I bought a dual OPA627AU from eBay seller hkaudioparts for $8.99. I was of course highly suspicious, but they actually do sound good. They measure 48K and 51K (both ways) between pin 1 and 5, which seems legit.
 
Top marking: BBOPA 627AU 9922
 
Genuine?

Exactly.

 
I just received a second one from the same seller. These measure 49K and 46K respectively, and looks exactly the same, except for another batch number (9914).
I wasn't able to find anything about this seller anywhere on the internet, but I'm pretty sure he is trustworthy now (and cheap as hell, I might add).
