Network Switches

@thyname I am unsure if that will work for me as my optical modules are not Gigabit but only 100 Mbps.
From what I have read I believe switches like these and the SOtM one need a Gigabit connection.
The reason I asked is because I was under the impression that switches are used only when you have more than one upstream or downstream connection.

If I am using a pair of FMC’s ie. TP Link MC100CM’s at router and then a BJC CAT6 to a single source ie. an Aries streamer, does adding a switch somewhere to the chain make a difference? Or does going fibre with the FMC's already provide enough isolation to cover it.

I only have a single source.

@thyname have you tried removing your Sonore Optical Module upstream and just running the ER via ethernet?

@thyname thanks for the feedback. I read other reviews and there are some folk who find the ER causing a loss of body and warmth and sounding too smooth and clean. If that is the case, I don't think it will work for my tastes. That is the impression I have had with other Uptone products in my system. I would put them in the category of "you hear more but may not like what you hear"
@david_ten thanks for the tip on the Japanese switch. That sounds like it will work for me. However, the price is staggering.
