Are cheap Hong Kong sourced opamps real?

I oredered some OPA2107 from Hong Kong. Installed and they play fine. But I replaced OPA2134 with these, and expected an improvement.
Maybe more playing time will improve things, but I think the OPA2134 sounded better. More airy and clear.
The seller shows OPA2134, OPA2604, opa2107, OPA627, and OPA637 at below Digikey prices. Wonder if these are all rescreened 5532 and TL072, or legit. Does anyone know for sure?
