Better Power Supply for a Router?

I agree that the iFi line is pretty good, and it’s cost effective.

I am not sure that a better power supply on the router will make a difference for you. I’d be sure that you can return it if you don’t hear a difference.

Another approach to this would be an Ethernet isolator like the ones made by EMO Systems. I bought one in a flush of audiophile enthusiasm, but I’ve got to say, I don’t hear the difference. I’ve kept it for its surge protection.

Leave the router alone and buy hifi switch. Silent Angel with stock PS.
OR
Go all ENO

@dougthebiker - funny I got into a debate with another guy in Agon about an upgraded router that he said was snake oil.
Seems he was more than just a little probably right. The more I researched the subject, the more a linear power supply affected the resulting sound quality. I now agree with him.

From the research I read, you're on the right path if you're going to sort out the power to it.

A better power supply definitely makes a difference on your router. I use a better power supply on my cable modem and NAS also. It will take your network set up to another level, That is if rest of your system is revealing enough to hear it. We all know that noise is your systems enemy. Wall warts are cheap and very noisy.

TBC:  Better power supplies don't make the networking better.  What they do is reduce the amount of noise they inject into your AC lines. I wouldn't go crazy putting expensive wall warts everywhere, but anything near the audio system I would.
