Power supply for ethernet switch?

@mgrif104 

“Some will still disagree or remain skeptical about 30 picosends of timing error being audible. So be it. But I would suggest that it’s no longer worth arguing over. It can be measured and some of us hear the improvement.”

I was simply saying that it was not clear whether the jitter (30 picoseconds?) was measured on the ethernet side or the output of the data buffer.

You answer does nothing to clarify this, yet you continue to trot out that something can be measured, so someone can hear the improvement.  You seem to have dropped the con from seconds but not necessarily from your post.

curious. - I don’t know why the picosecond didn’t copy over from my post. Another mystery.

As to your question - I won’t venture an answer as I’m not the author of that material. The point the author was making is that a switch indeed introduces measurable jitter.  

Before this study, many believe they heard improvements from upgraded switches. I acknowledge it could still be placebo, but at least we now can begin to consider potential deleterious effects of jitter with some supporting data.

The point I was trying to make is that it’s not worth spending time on as it’s a circular argument.  A point you seem to find unsatisfying.

@richardbrand your attack matches the definition of internet troll. 

It is explained in the article where the jitter was measured- look again. 

SILENT ANGEL BONN 8 network switch also has its own brand dedicated LPS … “ FORESTER F1 lps”

there is a pre-owned combo paired unit up for sale on CAM, priced in $CDN

Hi @erik_squires !  Thank you!! Appreciate the simple break down!!  Furman seems to be very reputable for solid distribution surge protection devices,  etc, and not any of the "immense sound stage, spicier peppers, brighter light bulbs, wetter water!".  I think the one you mentioned looks like a great choice for the digital devices like routers, modems, switches, small computers, maybe even DAC.  $300, a bargain too! 

Best wishes friend.
