@hilde45 I said ‘for a believer,’ but I am not one. I could so far discern differences with all cables except USB and power cables in my system. I simply wanted to pass along this price break for audiophiles who do believe in it.
Imho, cryogenic treatment will have an impact to the electrical properties but the benefits in sonic quality would be too small to be audible.
However, maybe with cryo technology, we can be frozen for another hundred years and wake up to massive advances in sound reproduction.
