As far as I can recall, everything that has been said in this thread by those who deny that the reported sonic differences are real has focused on the robustness and accuracy of ethernet communications. While ignoring or discounting what I would consider, based on my experience, to be the very real possibility of interactions between signals and circuits that are ostensibly unrelated. Designs should not be assumed to behave in a manner that is theoretically ideal, IMO, and signals should not be assumed to only follow their intended pathways.
Agreed, but that is going to happen regardless of Audioquest or WireWorld or Nordost.
Bottom line is there are only so many ways to engineer an Ethernet Cable and the standards body steers these considerations.
When a $340 AudioQuest Vodka was measured it was actually marginal for 6A operation for NeXT. Where as my $12 6A cable was 200% better in this regard.
I'm able to show up and terminate UTP CAT5 or STP CAT6 to the same as is whatever they are using. I understand the theory and not in disagreement. All the same I stand by what I have said I would do and that is show up with ~40-50 feet of cabling, terminate on the spot and with a L3MS in LAG let the claimant A/B sighted for 1-3 hours and then we can move through the rounds of testing.
