Cryogenic materials treatment involves little shock. You don't dump it in liquid. It is a vapour exposure.
It is not going to have a "sound". Copper conductivity is barely impacted and even if you caused some damage to the dielectrics, it would make 0 difference at audio frequencies. I would bet more cable to cable variation than cable to cryoed same cable change.
