Once again this is a question answered all too often by those who don't have a system that will reveal enough detail to let them hear differences so they must not exist.
I have a dealer friend that had one of his monoblock amplifiers cryo treated, we teased him for a month about his posicle and how it sounded like crap, it was terrible. But then after about a month of playing it started sounding significantly more detailed and clean. He had to do the other one so they would match.
The people who don't believe something works should ignore questions about the things they don't believe in spending their money on, the opinions they offer have nothing to bring to the table.
