The article puts things in perspective, from the engineering perspective, but I was waiting for the part where the author compared various cryo and non-cryo treated tubes to report the results to the reader.
It reminds me of articles about why cables, hi-res recordings, and other audiophile tweaks/pursuits are argued as being without merit.
I've never had any cryo treated tubes so I can't speak to what the process may or may not do with regard to the sound, which is the ultimate question for me.
