I am aware of at least 2 speaker manufacturers in the past and present that cryo(ed) the internal components/wires of their speakers. I can't imagine it is based on anything other than perceived improvement or possibly for the reason given by Glennewdick. His explanation is my understanding of the overiding benefit aside from having no benefit to NOS tubes, 1st time I heard that. I would say that sonically I have THOUGHT I heard differences, output tubes in an amplifier years back, this would have to be revisited before I decide. My understanding that there are different methods and that not all cryo treatment is the same. Someone else with more experience might chime in on that point?
Cryogenic treatment of tubes? Anyone with experience positive or negative?
I just ordered a matched pair of 12au7 mullard NOS tubes for my primaluna amp. Ordered them from upscale audio. They offered the cryo treatment, so for only 8 bucks more, I got it.
wondering if anyone has done enough listening to have an opinion on the sonic benefits, or the technical reason why it makes (or does not make) a difference.
