Help optimizing my streaming setup

@riccitone quite a few of us here have gone this @juanmanuelfangioii had posted it at one time, I screen shote it and bought the setup. Very nice. 

I suppose I don't really understand this topic very well. From what I hear, I don't see why there is enough RF in the house to notice a benefit. What the the metrics on RF which is audible? Any links to research on that?

Also, I'm not sure how one of the products above, which has isolation transformers, would help, as I've heard that all ethernet connections are transformer isolated -- it's part of the design.

In other words, I don't really get why these things are needed, from a technical standpoint.

@curiousjim I have a complicated set up as well. I have about 30’ from my home router and modem to a switch in my entertainment system. From there six devices get network access. For the best audio performance I should put the isolator right before the streamer, but because I’m concerned about an electromagnetically induced surge damaging any of the six pieces of gear I put it before the switch.

It turns out that inside a building isolators are better surge protectors than grounding devices, and the longer a cable run is the more likely it is to have a damaging voltage induced from a nearby lightning strike.

What could cause that?

What sort of isolator are you talking about, @erik_squires ?

@cleeds - I meant a nearby lightning strike. :)  A copper wire can pick up enough energy from a nearby strike to induce damaging voltages, even if it's not connected to anything on either side.

I was talking about ethernet isolators, I pisted an example earlier in the thread.
