I hope it's OK to ask for a clarification on this point. Are the SFP fiber ethernet cage and the isolated ethernet output jack two separate ports? If so, I guess I don't understand the role of the SFP cage.

rickca Posted December 27, 2018 Share Posted December 27, 2018 @superdad and @JohnSwenson can you please explain how EtherREGEN and Sonore systemOptique work together?

Would this yield any better results at the clean isolated output of the EtherREGEN, or is it unnecessary?

rickca Posted April 22, 2019 Share Posted April 22, 2019 @Superdad and @JohnSwenson with reference to the Optical Isolation block in @mfaoro's diagram ... What if that block is a Sonore opticalModule sitting between the router and the optical SFP module of the EtherREGEN. I then connect my endpoint NUC to the port on the other side of the EtherREGEN (with its own power/clocking domain), and my DAC is connected to the NUC via USB. Do you expect that this configuration would sound any better than just going from the router into one of the non-optical ports on the EtherREGEN? Given the isolation of the EtherREGEN output port, is there any further benefit to coming into the EtherREGEN with optical?

I love Larry's experimental approach to everything. A while back, he told me he got a new outboard motor for his boat. I suggested he should try mounting it at the bow rather than the stern to see if it worked better that way. 🙄 Larry's unconventional methods have given us some really valuable insights. I just like to kid him about it.

rickca Posted April 24, 2019 Share Posted April 24, 2019 OK so the EtherREGEN is symmetrical except for the fact that the B side is the native side of the clock generator. I hope I have that right. It sounds like there's no point to going optical after passing through the EtherREGEN in either direction since it already takes care of leakage and blocks upstream phase noise. Is that also correct? So if you have an EtherREGEN, an opticalRendu would have to outperform an ultraRendu for reasons beyond just having an optical interface.

However, the silly thread will say you need two ERs in series each with external reference clocks in order to get good sound. Also, for good measure the silly thread will say you need two linear power supplies that you have to wait over a year to get or it just won't sound quite right. I'm just saying... There's very little discussion of Sonore products on the silly thread. People need to actually try things out themselves to decide what makes a positive difference in their system.
