You so clever ! yes , i realy output by transformer , it since better than opamp .

Are you making this DAC board for sale on Ebay or at AliExpress? Do you have your own website?

The modified DAC in the other thread got -120dB distortion, as good as ESS says is possible with an ES9038Q2M: ES9038Q2M Board

Don't know about the board in this thread, but it would be interesting to find out more.
