Power supply for ethernet switch?

@kingbr I tried using an iFi iPower supply (had one lying around) on a TP-Link switch as well as on a Wi-Fi router and it did not do anything for me. Some people swear by upgrading the PS on a Router however in my case it just didn't work. Perhaps a LPS would have been better on a Router vs the iFi.

I have the Silent Angel Bonn N8 Switch and that made a significant improvement. Later on, I added an iFi Lan Purifier Pro (ethernet to fiber optical) which further improved things. I agree with Andrew of SGC that the optical module will make the biggest difference. That was a more dramatic upgrade in sound based on my audio memory.

@kingbr take a look at Alpha Audio.net, they test (and importantly, listen too!) power supplies and Ethernet switches. TP Link, which I also have, did not test as well as some, but sounded excellent, imagine that…can anyone say tube amp? 
 

I originally had the IRIS feeding a Topping D90LE by I2S, a world-class measuring DAC. Sounded great, detailed, transparent, clean, tight bass, extended treble, etc. However the Pontus NOS really took system to a better place, more organic, warm, yet still detailed and with more dimensional sound stage.   
 

Happy listening. Cheers,

@chipcalzone  Thank you. Appreciate you sharing that experience. Being that the Optical Mod from SGC seems to make the biggest difference I’m leaning in that direction and going full in on that package with the power supply, converter, etc. that said I can’t seem to get past the Silent Angel. Unfortunately I can’t do both. It’s either be the Silent Angel OR the SGC route. Still researching and trying to decide. I already have an Ifi LAN Silencer on my TP Link Adapter. 
 

@trivema thanks for the top I’ll check out Alpha Audio. And totally agree again on the Pontus. Did the same for me and damn if this thing isn’t built like an absolute tank!

Something else is that I also have an ADD-Powr Symphony in the chain. I was having some static issues when I introduced the Hermes. I removed it thinking that could be it. That wasn’t the case so I added it back in. Currently I have Ethernet cable going from TP Link adapter to Symphony in and then Symphony out to Streamer. I’m thinking the Symphony may have to go if I go the SGC route. I almost feel like you get to a certain point where there’s just too much in the chain and it starts doing more harm than good? I posted about this a while back…

so this Symphony is a box to improve "signal degradation from such systems of various cable interfaces", but to use it one has to plug in its own "cheap" switch mode power supply into your system? I don't know....
