Cryo Treatment: does it provide improvements in sound or longevity?


I'd be interested in hearing from audiophiles that have actually tried Cryogenic treated tubes and listened to them vs non-treated. 

I would really prefer not to hear from folks from a theoretical point of view, or that have no experience.

The last time I bought a set of tubes for my amp, just for fun I got the Cryogenic treated ones. They are replacements on my Audio Research Ref 160s. My KT150s were approaching the end of life and I heard them getting hard sounding. So I switched them out. The new tubes immediately restored the amp to its beautiful normal sound. I heard no difference from Cryo... although if it was subtle... no way I would... this was no purposeful comparison. I guess I'll have to wait 3,000 hours to see if they last longer. 

Just wondering if someone with good equipment and a trained ear has done listening tests (not measurements) and made a conclusion.

There was another thread about Cryotone tubes. This is not it. I will admit that other thread made me think about the treatment and start this thread.

 

I think this is the thread you were talking about.

Yeah, I know, start a thread and if you don't like the responses start another one and redirect in a way so that you get the responses you want rather than add a post to the original thread and simply changing the tone. Hence, my confusion and completely irrational post!

What in the world are you talking about? The two threads have different OP's.

@bolong Interesting I can’t find the thread that @ghdprentice and I were just referring to.

Yeah, and no longer a link either!
