<br />I've said it many times <b>but cryo treating tubes is a waste of time.</b> The heat/cool cycles the tubes undergo during normal use will anneal any kind of supposed benefits from the cryo treatment process. I also tend not to believe the hype over a change in tone .

So you disagree with Guitarist mags opinion that cyro treated valves are an improvement on standard valves then? They believed there was a definite improvement and gave the review products nearly 5 stars. Are they wrong?
Are the people in the Aurospace industry who also cyro treat many electronic bits for space missions wrong?
I can understand the views of Guitarist are just their own opinion, but I would think the Aerospace Industry base their views on more than just opinion.
As with all of the equipment we use, the best judges are our own ears.

I disagree with the Guitarist review yes. As for the aerospace industry, <b>i beieve they stopped using valves in the late 50's early 60's. </b>
Think of it like this:
All matter is made up of atoms. In metals, they pack together in a lattice like arrangemant in a crystalline manner. All matter above absolute zero vibrates and is subject to diffusive flux - that is, the atoms can move around within the metal for instance. Now then, cryo treatment is supposed to fix the atoms and realign them...i dont quite buy that myself. You do cryo temper metals such as stainless steel but ...

I agree with JXG that they, and things like mains cables, perhaps sound different.
All I would say, is that it doesn't really matter. As with a lot of things, sometimes it's all in the head, however, if it makes a player happier, then perhaps they end up playing better. Who knows?
