Are cryo'd tubes always better?

I recently purchased a tubed phono pre. I read upgraded tubes can greatly improve the sound, so I purchased some cyro'd tubes to go with it. Im waiting for all to be delivered.

The experiece prompted me to post my question: Are cryo'd tubes always better? Is it a matter of longevity or sound quality or both? Thanks in advance for your responses.

Always? Dunno, but from my experience with a couple small 9pinners, the cryoed version was 'better' or more to my liking than the non-cryoed versions. Batch numbers were not closely matched so it coulda' been just due to sample to sample variations.
