1 - blind testing shows no link
I read through the links you posted in your thread. Thank you for taking the time to put that together.
It may just be me but I did not find any of the blind tests pertinent to cables to be well conducted, for example this one:
If someone had never heard different cables before or was only working off of preconceptions how is this in any way yielding pertinent results? As one of the people in the experiment noted, he developed preferences consistently for each of the cables. The other issue in general for these is the sample size.
2 - actual construction eg silver vs copper shows no link
Perhaps the handling of current of different highly conductive metals is not different? From an MO (molecular orbital) perspective I don't think that would be far fetched. I would say impurities would have more effect if there is a difference, which to my knowledge has not been answered (at least for me).
3 - any apparent link is a weak one and is based on finding differences in cables such as eddy currants and then suggesting that they cause sound differences. Other reasons such as placebo are ignored in reaching such conclusions.
I feel that you are implying that eddy currents are a made up phenomena? It is apparent that eddy currents exist (they have to as long as there are impurities), however the question is if they are audible. Placebo is not ignored, but if someone is looking for an explanation it seems that using placebo effect as an explanation would be one of the last steps.
