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.

I have a Cryoset pair of Tungsol reissue 12ax7 that got a bit noisy after a month of use.  A standard pair was supplied with my Jolida amp and there seems to be no difference between them other than the standard pair did not get noisy.
