Why do I need a switch?

I use a Netgear PL1200. Then I run to a netgear 5 port switch. It sounds great. You can get faster models of this type if you want.

There are other brands too, but the Netgear network through AC wire has been solid, easy to setup with pressing two buttons. One at the router and then at the Streamer location or desired device. This is not Audiophile stuff, but let me tell you it would be worth the cost to see if it meets your needs. I am very picky, not a critic, I just love HI Fi accurate sound and excitement from music. It sounds very good. It comes back with no intervention after a power outage. It just works slick. I have had flawless sreaming for 2 years now. A use the netgear switch to go between my Innous Mini Mk III, and a bluesound 2i.

First, know I have fully gone to the Dark Side of internet switches.  I started with a Etherregen with a quality LPS, added a SOtM with a quality LPS switch then the English Electric with a quality LPS.  I clock the Etherregen and SOtM with a Mutec Ref10.  I have the ENO Ethernet filter and several SOtM cables with filters.

My experience is more is better. 

If you want to start slowly I would suggest the Eno Ethernet filter, you should hear an improvement and if not send it back and stop.  From there a quality switch will bring another level of betterness.  The switch is a sum of its parts but key parts are the clock and power supply.  An off the shelf switch is not going to have a decent clock so don’t try it and its power supply will be noisy.  An external LPS is going to lower noise and you should hear it.

There is a level of diminishing returns depending on the resolution and noise of your system.  I am all in with streaming.  I used to believe streaming (Qobuz) could never sound close to a CD or ripped CD.  Now I know otherwise.

@curiousjim It’s way to early decide anything, but without buying another $500 power supply, is there any decent LPS’s that have two or more 9 volt output connections that I can use on these network boxes?

I used one of these from Solupeak on the streamer end, though my FMC's are 5V:

The price has gone up significantly since I bought mine in December, but still affordable. I can't say that adding the LPS was night and day, but overall the fiber has been a nice upgrade.

Forget the switch. If your sound is noisy, get a Ethernet-to-fiber then back to Ethernet setup going to your dac and you will clean up the signal.

As for getting multiple switches to clean up the signal, that’s nuts. But if you can tell the difference, whether it’s real or not, then do it.

The reason I am trying to add a bit of fiber is to remove noise. If you have fiber coming into your home and modem, then you are good to go. You could try running fiber out of your modem to your router, but you probably won’t hear any difference.
