I don't know how the Chinese sources can sell the OPA627 so cheap. I went to DigiKey to check their price. A pair of OPA627 needed to replace one OP275 will cost $50 at DigiKey. I will need 4 for the SMSL1955 which is pricier than the DAC itself!!

I ordered the OPA627 with the single to dual adapter from this Ebay seller.
I made a mistake. Those are single OpAmp, not the dual. It took 3 weeks to ship. I am giving up and will go back to the OP275.
