Power supply for ethernet switch?

I have the SILENT ANGEL Ethernet switch powered by the SMALL GREEN COMPUTER external linear power supply, for it.

I was a card carrying agnostic and high skeptic that upgraded audiophile ethernet cables , switches, and external linear power supplies for them were rubbish …., until I watched the Hans Beekhuyzen Channel videos on YouTubr.. These are even handed learning tools without any of the usual shilling or BS hyperbole or pushing paid-for video promotions.

I took the leap of faith and upgraded finally …..

my take:

yep….they all matter individual and collectively in digital audio performance. And they are worthy upgrades staying in my system.

Fwiw ., ignoring the positive improvements of the Ethernet audiophile grade switch upgrade and Ethernet cables upgrade themselves, the SGC linear power supply was a great  upgrade to the “better-then-most OEM” switch mode wall wart supplied  with the new unit.

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?
