At Jena labs they use -329F (liquid nitrogen) instead of -300F (dry/gaz nitrogen) for cryogenic treatment. At -329F, this process perhaps offer slightly a better result especially on nude metal, but it might not be safe procedure for assembled cables like mine having several tight shielding/sleeves. It is fair to say, Jena Labs is among pioneers in US to use cryo treatment on their cables. Other cable companies like famous brands they usually don't use this process, maybe because of its cost! This is the case in Europe too! However, in Japan almost every cable company is performing this process on their cables.
The cables were sent for cryo treatment and once back, I will write down if there is any improvement!!???!
Because, Cryo treatment changes molecule structure of the metals, I guess I need to break-in (cook) those cables right after!?
@tecknik Did you need to break-in cables after cryo treatment?
