Cryogenic treatment of an LP?

The cryo'd steel (or aluminum) rod vibrates less when struck with, say, a wrench or other tool, more of a "thunk" than ringing. I actually cryoed all the steel or aluminum rods for one of my products (isolation stand) way back when for just that reason. Is that scientific enough for you?

The ultimate cold stamper.

Geoffkait - So you're saying that you're willing to compare the sound of a hammer blow to a piece of metal to what happens when an LP is cryo'd?

If this is the common result of cryo treatment of metal why would people cryo brass instruments?

A different frequency isn't directly related to the magnitude of the vibration in the material. I'm not saying that you didn't hear a difference, but higher or lower notes could simply sound different in your "listening" room.

I'll have to think more about what you describe, but it sounds like you're saying that cryo-treatment made things sound dead. I better not cryo my Nordost Sort Kones or they may turn into isolation rather than coupling devices.

"Geoffkait - So you're saying that you're willing to compare the sound of a hammer blow to a piece of metal to what happens when an LP is cryo'd?"

Yes. But I did not say hammer blow.

"If this is the common result of cryo treatment of metal why would people cryo brass instruments?"

To improve the sound and to make the fingering of the valves smoother, to name two reasons.

"A different frequency isn't directly related to the magnitude of the vibration in the material. I'm not saying that you didn't hear a difference, but higher or lower notes could simply sound different in your "listening" room."

Thank you for not saying I didn't hear a difference. LOL

"I'll have to think more about what you describe, but it sounds like you're saying that cryo-treatment made things sound dead. I better not cryo my Nordost Sort Kones or they may turn into isolation rather than coupling devices."

That's kind of a semantic argument and kind of a strawman argument. I didn;t say things sound dead at all. I said the cryo material rings less. Should I assume you like things that ring? BTW cones respond well to cryo treatment since the material will become harder, thus transferring energy more efficiently. It's a materials science thing, right?

Geoffkait - I'll admit that I have reached the end of my ability to discuss this topic in a useful way. I'm not a materials engineer or an expert on the cryo process so I can't really get into the specifics of the process and how it relates to specific materials without doing more research than I'm willing to do. I'll wave my white flag and let people make up their own minds.

This Friday I should have the opportunity to discuss this topic with some people in the audio industry, specifically turntables, so I'll see what they say. I'm expecting them to say it matters, but doubt I'll get any real explaination.

As a final question, can you explain the specifics of how you compared the before and after to verify that you can hear a difference of a cryo'd LP?
