Anyone tried fiber into EtherRegen SFP?

That is true and an important point. I use optical as my router is 100+ ft from the ER.  I needed to try and consult with people on several different converters prior to settling.  Difference in SQ was obvious. 

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 am using a WireWorld Platinum 8 from my modem to the etherRegen. I guess just the opposite of what you asked.

From the etherRegen, I am running fiber to my Lumin X1. Way better sounding than with ethernet, I am also using the After Dark clock.

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

From your modem to etherRegen. Are using etherRegen’s B side( B port ) ?
