Ok..I guess we can pooh-pooh "OCC" (Ohno Continuous Cast) and "Oxygen Free Copper"
as pure bull,too? |

Different trade names for the same few grades of material.

Well said. Unfortunately for me (my bank account), I've been able to hear a difference. If you are not able to, take a nice trip (or whatever) with the extra funds.

I don’t think anyone said that, only that any claim to purity beyond 99.99 purity is suspect.

Wish the recording qualities of much of the music was 99.9999% so we can really worry about such trivial things as copper purity.

My father was a metallurgist....specialty steel industry including high-tech (non-copper) wire, think extreme aerospace and medical applications. Purity beyond 99.99% has been able to be quantified/measured for quite a long time now. I know you are saying such claims are suspect (which can be very true!) and not that such purity is impossible however if a firm is responsible they can publish accurate specs that substantiate the claim.

Big +1 on this!

No, that's not the case. The OFE specification includes a value for oxygen content and Ohno is a casting methodology, not a purity specification. They are completely different things.

Respectfully, they are not. CDA-101 and CFE-101 are "reference standards" for copper purity. Reference standards, by definition, do not vary. This is so that manufacturers using these materials can obtain consistency and conformance to specification of the materials in question.
