I have read it... well not the full article.. I know I am doing stupid things with the op-amps but still In comparison there is a major difference between opa2134 and opa 2604 in some departments.. one being stereo separation.. the 2604 reproduces the recording much better sepperating L and R channel... the 2134 not so much.. so there are some difference in opamps the problem is puting one in the place of other does not guarantie any gain inquality because the board is made for the other one.. on the other hand I`m pretty sure that the chinese guys have put this DAC together to work well enough.. and I seriously dough that they have done many measurements... or more like try to use chips that peole think are good.. and make `em work.. in this case with FX-Audio they have made a good sounding dac with not so much good sounding headphone amp.. probably by mistake... combining parts.. and copy other companys board layout.. soo.. no harm to try some other chips if they are also cheap... to see what will happen lol
