Power supply for ethernet switch?

Personally the fanciest I’d like to get is to use iFi power supplies with the correct V and at least the needed current.

My experience is that giving the switches good clean power is less important than the noise the power adapters can generate back into the AC line itself. For this reason you should keep such devices from being plugged in after your fancy conditioners. Put them on their own strip like a Furman PST-8 which has excellent noise filtering, and surge protection or leave them connected to the wall.

Also, be careful how you route your Ethernet wiring. I use shielded power cords and shielded IC’s in part becasue I have so many Ethernet devices. Try to minimize how and where your Ethernet crosses power cords and interconnects. Avoid bundling them together and definitely don’t put your Ethernet switch on top of your preamp. :D

Thank you for the replies! That helps! @erik_squires I had read that before that these should not be on the same outlet/conditioner as the rest of the system. I had already planned to use a separate outlet for the switch/power supply. Love the PST-8. I have everything else on the Furman Elite 20PfI.

@akg_ca thank you for sharing that. I saw that video as well with Hans and that got my attention. However I saw another blog where they measured the Silent Angel and no difference whatsoever with that vs a Netgear switch. In fact the individual stated he thought the Netgear sounded better...

My dilemma is what direction Silent Angel with Small Green Power Supply, or the Optical Mod, Converter, etc and go all in on the Small Green Computer setup? Costwise would be about the same...

Hello @kingbr ,

Like you I came from a Netgear switch.  I upgraded to the English Electric Bonn 8 and also an EtherRegen.  While I think these helped, it was marginal.  I sold both and bought a JCAT M12 Gold switch and oh my nice upgrade.  Then I added a JCAT Optimo 3 power supply and another significant uptick.  I think a quality switch, like JCAT M12, Network Acoustics Tempus or GTT DeJitterit switch make a huge difference.  The latter two come with a nice power supply.  I have heard all three in my system.  I think this is a better way to go vs fiber,

Did you choose the JCAT M12 over the Tempus? 

Hello @mclinnguy , great question.

I bought the M12 and Optimo a few years ago.  Later, NA came out with the Tempus and I had talked with Rich at NA about it, so I wanted to try it.  I bought it with a 30 day trial.  I think they are very comparable, but I did like the looks and fit and finish of the Tempus better.  The M12 looks (it is) more industrial.  But I could return the Tempus and not the JCAT, so that is what I did.  About the same time, I heard the DeJitterit switch at Cap Audiofest and thought GTT's  room sounded quieter and smoother than most all other rooms.  So Bill sent me one to demo, and I think the Dejitterit from GTT is the best.  It is more than a switch, it creates a 'clean network' for only your audio stuff.  It is an interesting read, as Chris at DeJitterit points out all the other crap in your home makes noise on the network.  Phones, TV's, smart things, lots of things.  So taking all that off and creating an audio only clean network seems to me to be critical.  Taiko does this.  I bought the Dejitterit and kept the JCAT.  So now I have: Verizon Modem > (audio feed only) > JCAT M12 w Sean Jacobs Power supply > DeJitterit switch (has its own power supply) > Audio Only.

All the TV and wifi stuff come off the Verizon modem separately.  My digital now sounds pretty amazing.
