Anyone tried fiber into EtherRegen SFP?

A lot of people are doing this now. Jon Swenson (eR designer) recommended using an FMC in front of the fibre. Which is what the EtherRegen does in reverse order, B > A.

I do this in one of my streamers. Since I do this and fibre I do not care about the crap on the bad side of the eR moat.

Some of the official sound police engineers on A’gon like to say the Swenson is a quake but for me the improvement in sound is real ducky.

BTW - fibre is all I use it it very easy to hear improvements with fibre in my setup. As I said before I have a alot of crap on the bad side of the fibre. The fibre and FMC clean this noise up, so the noise does not get into the DAC. How can I tell? I just replace the fibre for Ethernet and listen.

I tried the eR with both my Lumin X1 and Musetec 005 DAC + Sonore OpticalRendu (both fibre solutions).

Not sure if this paper has Swensons explanation of why a FMC in front of fibre is a good idea. It could have been in a thread post on some site. However, this paper may aid in understanding in this thread. Some people are posting that this is pseudo-science, but my ears are a believer, at least the eR as an FMC.

@chilli42 EtherRegen in reverse order like I use with my X1. The Sonore OpticalModule Deluxe, and a lot of other lower cost FMC’s. But these are not streamers.

I tend to think that the Ethernet input on a DAC is not good as USB. I have not bothered even to listen to the Ethernet on the X1, when fibre is available.

However, the easiest way of getting the Ethernet converted to fibre is getting a network switch which has both Ethernet and Fibre SPF. Such as this one that I have. I paid $125-$150 for this one, It has been jacked up to $400. I have another similar switch in the Livingroom that cost $75.
