Blasphemy... I scoff in your general direction...
The important stuff, I print, hi light, and mark up. And I hit the antique bookstore every once in a while.
If you refer to the Essex echo article, that was so thoroughly debunked it wasn't funny. Bait and switch (replace the copper wire in the test setup with a high permeability steel wire according to JC) to support a preconceived notion is not looked upon nicely.

What does full wave rectification have to do with it? Are you trying to use a bog standard radio shack meter to measure wire?
Try an AP. I suspect they didn't use a full wave bridge at their inputs.

Scott, JN,
In wiring most folks are using, temperature rise is the limiting factor on gauge size. Apparently causing the insulation to fail is a bad idea. I suspect none of us disagree on this.
I did have one electrical inspector have me change 10 gauge wire to 12 gauge inside some if my racks. Easier to do than get the zzxghehhxc to comprehend the National Electrical Code.
As to high voltage transmission lines, there are significant cost savings to running existing lines at higher powers. I do know an energy lawyer who has participated in trying to clear new right of ways for energy transmission use. To put it mildly he got "diss'd" by a fair number of rich and famous for not in my backyard (actually view of the landscape.)
They used to make the HV steel messenger core wire locally. However they did close the plant as better methods and kinds of steel now exist. But it was a biggy circa WWII.
I do have a spool of medium voltage cable for inside use. It only has a half inch of insulation all around the copper plated 12 gaugish steel core.
So unusual for this thread I don't think we are arguing, actually having a discussion with added insights from the participants.
Of course to keep things on track I could insult someone, but as it is a holiday weekend I think I will just stay in mellow mode.

I have a bookcase design I use where the sides are a 1" x 2" maple frame with 1/4" flat cut plywood inserts, similar for the back. The shelves are also thin plywood inset into similar solid maple pieces front and back. The shelves are not adjustable. The design allows me to be able to move the shelves (around 35 pounds) very easily and the can hold a full load of books.
The strength secret is the shelves are rigidly attached.
So far I have made a few dozen and need to do another run as my home library is out of shelf space.

The discussion in recent says reminded me of some comic relating to physics, engineering and philosophy. Not only could I not find it, but after looking at so many others I can't remember what I was originally thinking of.
Regardless, I think I found the URL of a comic that everyone should agree sums up recent discussions in this thread:

I took care of that for you.So unusual for this thread I don't think we are arguing, actually having a discussion with added insights from the participants.
of COURSE we're arguing!! Your just too dumb to realize!!!

Stay mellow, my friend...Having lots of fun with the mini mill.. It's amazing to easily make parts with .001 inch accuracies, the dro's totally rule! Now I can make parts that are identical and fit.

The same tired arguments. I still don't recommend silver, unless you specifically know what you are doing, because it has a tendency to sound 'bright'. Not necessarily hi freq tip up bright, but maybe 'higher order distortion bright' or something similar. Even Xover distortion in amps can make them sound 'bright' and when you remove this xover distortion by simply increasing the output device bias, becomes suddenly 'neutral' and then you might realize that you need a tweeter. This actually happened once.
I had an "electrician" wire an electric range with #10 wire and I him to do it over. He said as long as the breaker was 50A it would be OK.
I'm sure you can discriminate, and would had talked of distortions. Which ones are also easy to be measured.
Anyway, if it was some distortion added by the silver wire that made the sound brighter, why the hell a straight wire with better conductivity should generate more distortion (if any)than a coper one ?
John, I do not question your ability to listen, quite the contrary. Not even that your silver cable added some "shine" to the listening. Where I can not follow you is when you suggest that these differences would be due to the metal from which the cables you compared were made.
Long time no see; nice to see to you participating.
While i agree on the importance of processing both (envelope and spectral information) i don´t think that the stimulation of LF HCs will be (very) different if a fast attack occurs.
From the literature it seems that attenuation of the TW is quite effective so that higher frequencies don´t have an impact on the far end of the BM where the low frequency decomposition takes place.
Although the tuning curves for each frequency band show the v-shape when increasing the level there is little expansion above the CF while the broadening (and typical tail) for frequencies below the CF is more pronounced.
So chances are higher that high frequency bands are reacting with neuronal activiy (above the spontaneous rate) if low frequency soundwaves with higher levels are present than the other way round.

If anything, more likely not the wire in isolation, rather something going on at the connections to the wire.
My interpretation of what S&M posted was that a bass note would reach an audible amplitude faster when the risetime was steep than with a less steep risetime. What I wonder about is how this would be audibly perceived?
I must admit not having tried to figure out which configuration the calculator number is supposed to cover.
The calculation of inner-inductance (maybe the correct term is self-inductance?) is useful as it is often needed for the correct calculation for a given loop configuration.
Inner-inductance of a round conductor is ~ 50 nH/m and (at dc and low frequency currents without significant scin effect) and accounting for it (and the inner-inductance of the shield as return conductor) helps to get the correct result for a coax.
