Better Power Supply for a Router?

@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.

I work in the networking industry (Cisco 17 years, Broadcom 3 years), it is ALL snake oil.  The power supply it came with is adequate.

@cakyol, it's good to hear from an industry expert.  What are your thoughts on the quality of ethernet cable running from router to streamer... and what about the quality of the router?   I'm using a simple Google Nest router with stock cable into my Bluesound 2 Vault streaming Qobuz.  Should I stick with what I have or can sound quality benefit from an upgraded router and upgraded Cat 7 cable?
