Looks like your argument is based on this video ~ https://m.youtube.com/watch?v=anZeheEiff8
That would be because that's my video. I would really like to have someone answer what happens to the characteristics of the audio when the system doesn't even have a cable connected to it.
The video clearly shows the track is never interrupted even though I did plenty of swaps from $27 a foot and $0.30 a foot cable.
Everything was stacked, and incredibly so, in favor of the WW cable.
The other tidbit is that on some other testing: No packet loss for either cable on the transfer of 4GB of data.
Also the the Cisco SG 200-8 is bandwidth limiting at the 60MB/s you saw. Going from NIC to NIC, for both cables, I maxed out at 107MB second. So while I like the SG 200-8 for the L3 capabilities, it's not what I use as my backplane switch.
