Hello everybody. They gave me a Pro-Ject Phono box S2 phono pre that has two JRC 2068 op. amps inside, on my old Cambridge preamp I remember replacing these opamps with BurrBrowns, do you think it is possible to do the same thing? I have heard good things about the new OPA1656ID which have high gain and very low distortion. I ask someone who maybe has already made this mod or knows a lot more than me. Thanks again.
