Fiber to my Etherregen… Sonore OM or generic?

Supposedly they induce less noise. But I am uncertain if that noise (or the difference in noise between genetic and oM) is audible. And I do employ the prior gen Sonore oM from my NUC to my fiber optic network.

I always recommend using a linear psu on any and every FMC. They really do make a difference. 

What I can add is that I am using an Ether Regen sending the fiber cable direct to my Lumin X1. The difference in sound quality between usb and fiber was quite revealing.

you can choose your preferred sfp/fmc modules, but always remember the reason for doing this is to eliminate electrically borne and transmitted noise at the receiving end...

... so that end (not the sending end) needs well performing sfp unit with a highly filtered, very quiet power supply -- so that electrical noise is not re-introduced at that junction (thus defeating the purpose of the whole exercise)

The receiving end is the Etherregen itself powered by a relatively inexpensive 12V LHY linear supply.
Are you suggesting a higher quality SFP in the Etherregen than in the upstream FMC.

I do have an extra 5V Ifi power x supply I was considering using on the transmitting FMC.

Also, one more question:

For the upstream equipment ( Modem, Router, FMC)… can they all be on the same circuit plugged into a Furman PST?

Conversion is an error likely, potentially noisy process.  If your internet is delivered in fiber, use the fiber input.  If not, stay  with the copper based system.  going back and forth does more harm than good.
