Power supply for ethernet switch?

Hi, All,

 

LOVING my DENAFRIPS Hermes/Pontus combo! WOW what a difference adding the Hermes made. I could not have been even hopeful for the improvement this made!

 

I just bought the TP Link TL-SG105 Ethernet Switch. I have been contemplating so many different paths here, including the setup from Small Green Computer with the Optical Module, power supply, etc. Very intriguing. But that's a little expensive and a lot of added wires,components, etc. I was also looking at the Silent Angel Bonn N8 switch...Would love to get some opinions on just adding a power supply to my new TP Link switch or would one of the other paths mentioned above be better?

 

If adding a power supply to the TP Link would be a worthwhile improvement, any recommendations, maybe even the 5V power supply from Small Green Computer?

Thanks in advance for your time and advice😊

E-net switches do not use a lot of power, demand stay around the same regardless of what is being passed through it.  If it was a POE switch, then a power supply would make sense. But on a regular couple port switch, don't think it's worth the time and money. 

With a cheap switch, it should not be plugged in with your stereo. I'm sure the cheap switches have no noise rejection protection, generally electrical noise is not a concern with switches. Not only that, but the way the switch works, it will not transfer power noise to ethernet. 

Ethernet is not a audio signal, it's digital packets.

Think everyone needs to read this, to get a fundamental understanding of how ethernet works.

It's so different from an audio signal, noise can not piggyback on a packet. Ethernet jitter will not affect sound like audio jitter. It's completely different. Jitter in e-net can just slow down transfer, in worst case just have the packets be retransferred, greatly slowing down transfer. 

IMHO, when someone gets a better PS for a switch, the increased in sound quality, might just be from removing the noise from the home power. I can see where if you have a crap PS, and get a clean PS that maybe the router might be able to process things better, or just work a bit better in general. 

Money is much better spent in just getting certified CatX cables instead.
