It has not been established entirely that the liquid cryo process is actually superior to the vapor process and reports of superiority could actually be a simple case of expectation bias. My understanding is that the liquid dunking is only employed at the end of the cryo process which makes sense since the whole cryo process must be carefully controlled (ramp down, dwell and ramp up) over a long period of time in order to avoid thermal shock of the materials. Furthermore, simply freezing in the home freezer can be very effective and permanent so I wouldn't put too much stock in getting much from a 29 degree difference in cryogenic temperatures. Besides why hasn't some enterprising person cryo'd using uh, even colder temperatures. Nitrogen is not the ultimate gas temperature wise. |
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? cheers, michel |
From what I know and what I have been told, most materials can survive the cryo process and come out intact, with the exception of "pure rubber". Pure rubber will disintegrate during the process. Synthetic rubber and most plastics are unaffected, I have seen where some cheaper vinyls have become stiff or rigid. We run 250ft rolls of cable, boxes full of HDMI's, 100's of assorted types of plug sets in assorted metals and we've haven't had any issues. Glad to hear NitroFreeze could help you, they're good people, very helpful. Rick Ice Age Audio |
Thank you very much guys for the infos. I talked to several companies and seems NitroFreeze is more professional. thanks Rick! BDP24, my humble experience is limited to Hubble duplex outlet (Cryo vs. Non-Cryo treatment). The sonic difference is really audible. For my power cords, I keep my expectation very low and even like 10% of improvement would be greatly appreciated! As mentioned on divers sites the most commonly noted improvements are:
My recollection is that these Cryo treatment for cables is done more on nude metal (copper or silver) before adding shielding and other level of sleeves. In case where cables has already multiple levels of shielding and sleeves (like my Custom power cord Company pcs, CPCC brand), Cryo treatment might make cause some cracking on cover or sleeves. Is there any thoughts about this issue?! thanks, Michel |
This is Rick with Ice Age Audio. There are multiple locations around the country that offer assorted methods of Cryogenic Treatment. In my own personal experience it can be expensive to treat individual pieces. You can use NitroFreeze out of Massachusetts, you can reach them at 508-459-7447, ask for Bryce. NitroFreeze runs a cycle once a week, they start their process on Fridays and it comes out on Mondays. You will need to pay shipping both ways and I believe they have a minimum charge, It was $50.00, but that might have changed. Cryo facilities normally charge by total weight, the more weight the lower the cost. Individual pieces weigh nothing therefore you have a minimum charge. In some cases it's cheaper to buy a cryo treated cord than it is to have only one cord treated. I hope this was helpful, good luck. Feel free to contact me directly through my website www.iceageaudio.com if you have any further questions. Rick Ice Age Audio |
This company was very prompt and professional with my speaker cables. http://www.cryone.us/ |
