Re: Answer.

Living in the UK and using Schuko in preference to UK13A, and wishing to try the Oyaide Schuko plugs, I wondered, too, about the value of cryogenic treatment and the claims made for it, and wondered whether I should purchase plugs cryogenically treated, particularly given expressed preferences for said.

I have found the cryogenic treatment of tubes to be double-edged, and have come to prefer the 'sound' of tubes that have not been subject to cryogenic treatment, though initially I was taken by cryogenically treated tubes.

European suppliers of Oyaide do not offer cryogenically treated Oyaide plugs.

I decided to contact Oyaide through the e-mail link on their website.

I had a courteous, candid and informative exchange of messages with 'webmaster@oyaide.com', whom, I could infer from comments made in messages — “... I make a good product”, for example — might be the head of the company. His answer to my enquiry as to why the Company itself does not offer the product cryogenically treated was as follows (I would not think my correspondent would object to my reproducing his words, as received, here):

“Our product is shipped in the state that does not work to cryogenic treatment. And it is worked to cryogenic treatment a product sold in U.S.A. locally.

“I accept a change of a sound by cryogenic treatment , too. But, our company does not make a thing without scientific grounds. We are confident of a manufacturing process, materials, a plating method. And scientific in them; is well-grounded. And there is a scientific reason in them. But, we cannot show a scientific reason when cryogenic treatment arrives. Therefore a product of OYAIDE does not work to cryogenic treatment.”

My respondent did, however, add:

“If you want a plug of cryogenic treatment, it can process it in Japan.”


The respondent, clearly, does not deny nor dismiss an effect of cryogenic treatment on the sound of the plug (or, implicitly, the socket), nor, indeed, express a preference apropos the sound of the product, with or without treatment, but gives another reason for not cryogenically treating the product.

With own, albeit, limited experience of cryogenically treated components in audio and in the light of the comment of my correspondent at Oyaide, I elected to buy the product as released by the manufacturer.
