linear ps for switch and routers

Posted by: French Rooster on 28 March 2017

i read recently an article of jason kennedy in the ear magazine.  He writes about the ways to improve streaming audio. He recommends cad audio ground control and also mcru linear power supply for router and switch.

I have already tested entreq audio on my preamp and was not convinced : the sound was clearer but less life.

But maybe linear ps for router and switch, not very expensive ( 235 pounds) , can put off noise of switch mode ps that are on routers and give also quietness to switches...    Has anybody tried this?    I have already an optical bridge between switch and nds, very inexpensive but with great results.

Having dilly dallied for too long a I finally got round to buying Mrs NewNaim16 a pre-owned Cisco WS-C2960-8TC-L Ethernet switch and she's thrilled   As an ex IT person I couldn't help but be sceptical. However, the improvement in SQ is very real with some worthwhile improvements in musical nuances and in particular, even 'crisper' cymbals. 

@Simon-in-Suffolk: Thanks for drawing attention to this (for us) very worthwhile enhancement. A tad embarrassingly, it reminds me of when I didn't want to move from Wi-Fi to hard wired Ethernet cable but guess how that ended

actually, I have a technical question on the topic - I used to only have a NAS and NAC 272 connected to my router, a Cisco WS-C2960-8TC-L. Now I also have a music server on the mix which hosts my music library.

In my living room, I only have one Ethernet socket.

To my question:

1- can I simply connect the music server to that same Cisco router?

or

2- should I have a 1st switch that connects both my music server and the second switch (Cisco)? that way only the NAC272 and NAS would remain connected to the Cisco WS-C2960-8TC-L

Not sure it matters but I thought I'd ask the resident experts...thanks!

That's what I've done, in fact I'm listening to it now. In my case the music server is a Mac Mini.

Really depends on how much noise your NAS dumps on the switch.

i saw an improvement with connect a netgear switch with the wall and the NAS and the Cisco router. The CISCO router was then connected just to the netgear switch and the NDS.

The 2960 isn't a router, it's a switch.

[@mention:4804681823084713] of course it's a switch, thanks for correcting.
