francesco,
You may want to talk to Gene at Take Five Audio, who does all my cyro treatments. He has had years of experience with the cryo process. I agree with his conclusion. The better the quality of the wire the less effect the cryo treatment produces. However, I have treated very pure single crystal silver wire that already sounded excellent and still realized a noticable improvement in sound after cryoing.
