LOL!
I guess the dia of this wire would be very small, given the good conductivity of silver. Not to mention it's high melting point (compared to most fuse materials) makes the amount of heat required before the fuse, well, "fuses", requires a higher resistance wire, which means something thinner, if you've already fixed the material.

CDA alloy 10200 OFHC requires a minimum 99.95% copper. CDA alloy 10100 OFHC certified requirs a minimum 99.99% copper.
You seem to be assuming that everything past 99.95% or 99.99% is oxygen. It's not.
What websites are you looking at? I just picked the first half dozen I came across and 0.04% seems to be consistent with all of them.

Sorry, I forgot about that.
So I should have said the following: of the two people who were absolutely sure of their ability to hear cable directionality, one reported unable to hear them, and another was never to be heard from, when put under a test.
Either way, i am not sure if we would have concluded any differently, tho.

Well, I am not so sure either of them claimed an ability to hear
directionality in any arbitrary cable. That raises the question,
if Frank couldn't hear any difference in this case, does that mean
the cable is so good that it isn't directional or that it is so bad that
other sonic imperfections swamp the directedness. Since he
said it was a good thing not to hear it because he's lazy, I
assume he found the cable so good that he would be happy
to use in either direction.
Hi,
From past experience I'd say that more and more wire, remember this was just a piece of magnet wire, sold for audio exhibits no directionality at all.
This is probably due to more care being taken at manufacture, but that's just my guess.
The reason that I'm glad this is the case is that determining correct directionality is a PITA in that it's a major waste of time.
However, as I said before this is not an issue I lose sleep over as this directionality tends to disappear with use.
Quite alot of cables (read interconnects) are directional due to geometrical layout and this, of course, is a different issue altogether.
As far as the test of the 1 m length goes, well I made an interconnect with it by just cutting it in 4 equal lengths, twisting it and fitting RCA connectors.
I than hooked it up between my MC headamp and phono pre and listened to it, than reversed it and listened again.
As I couldn't tell one from the other even if I reversed one channel only, I concluded I couldn't determine any preferred way.
Hence my conclusion: I couldn't detect any directionality with this piece of wire.
Note that at no point in time the wire was marked and other than paying attention in making a correct send and and return cable; I reversed the negative run on both cables, I had no visual clues as to which was which in the tests.
Cheers,

I didn't assume. I said it SEEMED that you were assuming. I was just guessing as I didn't see a clear point in your statement:
After checking about half a dozen manufacturers websites, the average was 99.95% being called oxygen free copper.
Was there a point there?
