Anyone tried fiber into EtherRegen SFP?

Putting a 2nd-hand EtherRegen before my Innuos Zenith Mk3 has probably been the single best upgrade I've made.  Like most others' experiences, the shift away from a digital sound has been palpable.

I'm feeding the ER directly from my Netgear Orbi mesh satellite through a Wireworld Starlight ethernet cable.  I was wondering, however, if anyone has experienced significant gains from feeding the ER with fiber into its SFP port? 

I did assume initially that as the ER is a regenerator the quality of the input shouldn't matter that much.  But as I saw another jump when upgrading the ER's input cable it's set me to wondering about optical.




two further suggestions, if I may: use the Etherregen’s grounding post to run a separate ground wire to a good ground. And use a 10m clock on the Etherregen, even if it is only a cheap one. Both have major additional benefits

Thanks @antigrunge2 

First suggestion already done. Russ Andrews router connected to metre long copper rod stuck in ground

Second, thanks for the advice

I have a full fiber ISP and LAN.  So my ER is used to convert light to copper right before my PS Audio Bridge II.  Works great as a higher-end FMC.

Hi @antigrunge2 

Going back to your clock for EtherRegen advice, can I ask what you're using?

I don't want to spend silly money, and certainly not more than I spent on the ER.  I've noticed a Chinese clock, BG7TBL, seems to be a popular choice.  Do you know if square or sine-wave output is better?


YI use an Antelope Audiophile 10m Rubidium clock, having had the one you mentioned before to try it out. Preferred for the Etherregen is square wave but inly if it not done by cheap conversion in the clock’s output. The advantage is noticeable with the one you mentioned. a bit further upmarjet you get much better quality from LHY or Afterdark
