"Audiophile Grade" Ethernet Switches - The new generation

[octaviars]

@Confused From what I've picked up, from (e.g.) John Swenson's posts, the point of reducing clock phase noise is mainly to do with  its effects on the PHY devices, which might (it is supposed) inject analog noise into the DAC (e.g. via power/ground planes).  As you say, it should not have any effect on the timing of samples reaching the DAC because they are clocked out of a ton of buffer memory by a clock that is completely asychronous to the Ethernet.

I suppose we will have to wait and see what John Swenson can measure after he built the switch. Perhaps it will affect the DAC (I dont know why and how) but if it affects it is it something that can be heard?

It is safe to say that the market is shifting from USB gizmos that is supposed to isolate, re-generate and so on to more gizmos that is supposed to do all sorts of things with ethernet. The companys that comes up with all this stuff goes where there is money to make
