I have only used four cryoed cable, and did not have the same ones in non-cryoed versions to compare to. So I have no first hand observations on the subject. I would point out first, that it is a relatively inexpensive process compared to some of the stuff that we shell out our money on in audioland, generally only adding the cost of a couple of cds to the product, irrespective of the vernturesome pricing of many audio manufacturers. Second, many that I respect, and have the ability to carry out testing with good gear, over a long perious of time, such as Albert Porter, are convinced that there is a benefit from this inexpensive process. Keep an open mind, I do.
