Cryo'ed LP's

That's odd, Highendman. There are quite a few cryogenics labs specializing in audio items - including LPs - such as Cryogenics International and Enduro Cryogenics. One suspects that if properly controlled cryo treatment of LPs produces warped LPs these cryo labs would have ceased to advertize LPs as one of their specialties a long time ago, eh? You know, with customer feedback and all.

Cheerio

Geoff, You were not serious about "cryo"-treating your LPs using your home freezer, were you? I assume you know that temperatures attained in a home freezer are nowhere near low enough to have any effect on molecular or atomic organization of any material (except of course for freezer burn). OK, you were kidding, and here I am taking the bait.

Has anyone really cryo-treated an LP with good results?

Yes, I was serious about the home freezer and, yes, I realize the temperatures are not as low as cryo temps.

Geoff,

I used Cryo International. They listed LP's as one of the items they cryod. Mined were all destroyed.

Highendman, the only things I can think of are (1) the proper ramp down, dwell and ramp up timing protocol for LPs was not employed in your case for some reason, perhaps an error or (2) the LPs were exposed to excessive heat somehwere along the line during shipping/treatment. Did you discuss the damage with Cryo International and, if so, did they provide an explanation?
