Cryogenically treated cables

Stan Warren uses dry ice for all his mods and cables. He did tests with friends at a university in Oregon that had access to frozen nitrogen and they concluded dry ice is cold enough. So you can do it at home. If you call Stan Warren, I am sure he would tell you how he does it. His number is available on other threads.

Jena Labs offers no proof dry ice is not cold enough (may not be), they only offer their say so, which conveniently justifys them as the only person you can go to. Anyone who claims their Cyro process is the "only" one available is lying big time. Anyway, who really knows if Cyro does anything perminent?? If the effects also wear off, your audio memory will never notice a gradual change.
