Garfish - Rainchild wants to know what cryo does. I do not have cables that differ only in cryoness, so I can't comment. I have as much knowledge of its effects as you do. I would be surprised if there was not a difference under certain to many circumstances. Your experiment, however is confounded, but not only do you claim cryo is beneficial, you claim to know how it affects the sound, by repeating an ambiguous statement from a website. That can be misleading and is what I reacted to.
"However, I've read many, many positive reviews of the beneficial effects of the cryo process on parts that could affect music quality, and I wanted to try it myself-- so I did with the above results. I read a lot, and get much information that way, and yes some of it is advertising."
Thanks for answering. All I wanted to know is how you became so sure from the very weak evidence you initially published. Something as potentially subtle as cryo requires stricter conditions. As far ridiculous, I think it would be easier to admit that you don't really know than to hire an electrician. Maybe you share the source of a couple of those many, many convincing reviews for R.C. and others to look over.
"Is all advertising false?"
Oh gee, ummm, no.
"or does some meet with approval?"
If subjective(especially), I would think it would at least have to be substantiated, which is what has not been done.
"Please enlighten us."
If you to answer someone's question with an subjective advertisement claim, then the contribution you made is worthless. VD's cryo claims are unsubstantiated in this thread, and VD's cryo goals are obvious. You tried to make a connection between your experience and VD's cryo claim, but logically(b/c of your confounds), you can't do that. Happy birthday
