So, I've seen a lot about various ethernet switches that offer benefit in an audio network. Not sceptical, but interested in the reasons why this may ben beneficial.

Has anyone observed any significant benefit from using a purpose built switch (i.e. SotM/EE) compared to using cisco consumer kit? If yes, where might that benefit be coming from?

Ideas (good) and data (better) welcomed :D

Measurements will show you that this products don't do anything useful.
This is no surprise as using a "normal" switch all bits arrive correctly.
Jitter is a non-issue either as all input is buffered at the receiver.
This leaves the "noise" as the culprit.
However, a ethernet nic is galvanically isolated by design.

Examples:

Great stuff, thanks - the links were very helpful, as I wanted to see some FFT analysis on jitter to test the 'clock' theory. Seems that data shows no technical benefit, and that performance is almost wholly down to the level of isolation/filtering at the inbound ethernet connection..

OMG, is this seriously a thing now? I thought I'd heard of every snake oil scam after I saw those myrtle wood blocks for your speaker wires that were supposed to "decouple" the wires from the "ground plane."
