Doubtful the OP intended this as a joke thread. Maybe turning it into one would be a way to try to divert attention from the fact that resistors can affect SQ?
Carbon Composition is made like Thoreau's pencils. Clay and finely ground coal, blended to desired darkness/resistivity. (Thoreau's family was working to replace natural graphite which was a Crown Monopoly and also running out.) Press, coat with clay, add leads, bake.
Carbon Film is: puff propane or other rich fuel gas in a seal pot, ignite it, and spin a rack of ceramic bodies through the soot. Terminate, seal, sell.
There may be sintered carbon resistors but I don't think they are common. (Yes, the soot-film is sort of sintered.)

Well, you are just adding an extra joke to the thread 😀
"No, no, I´m SERIOUS!!!!! 😡😡😡😡😡 Can you answer my question? it was resistors can affect SQ?"
Gimme a break, that is just another failed attempt at kicking the ball outside the field.
We are not talking the PHILOSOPHICAL or ABSOLUTELY UNRELATED question you are trying to inject to move the goalposts but the VERY SPECIFIC CLAIMS of the OP, concerning GROSS SOUND CHANGES caused in various commercially available resistors under millivolts of signal.
It has not been proven after 400 something posts (hint, I guess it can´t) and yours is just a desperate move to save face.
Can YOU prove OP´s wild claims?
So far you failed.
No that is Scott’s humorous explanation. I have clearly shown that diode action does not occur.
But you could read the article Jan posted and see for yourself.
I personally did not read the OP's resistor sound descriptions as claims of gross sound changes. Doing GROSS SOUND CHANGES can be challenging even in a DAW unless maybe using something as extreme as a vocoder. More likely audiophiles tend to know what they mean when they use certain language among each other, and that was the language used by the OP.
That would most likely follow for third harmonic distortion. Second harmonic is attributed to “Voltage distortion”. I have no handle on predicting how that behaves, although it is easily measurable.
The other issue is that I am measuring distortion under the best I can control conditions. The possibility although small exists there are other factors at play. It is interesting to note my measurements did confirm some folks opinions as to which resistors worked better. It is also interesting to note some folks preferences ran to the higher distortion rankings. Although some folks preference did not show any correlation with my measurements. So either I missed something or the asylum allows folks the use of the internet.
For my use I prefer the lower distortion types and some of the decent ones are quite inexpensive.
I did do a bit on other sources and compared to resistors high levels of distortion can occur from mechanical contacts and printed circuit board thru plated holes. All quite low compared to gain producing active devices.
To really confuse folks, air rarefaction and compression are not perfectly symmetrical!

Jim,
I don’t think the OP claims are that wild. Not when you look at folks who place rocks, freeze things and although not yet popular wave sticks around in the air while chanting bits.
He might get better results trying the different resistors in a feedback loop.

I thought I was the one who thought this thread has run out of reason and should be closed.
There are just too many nasty comments coming out.

He is. He can hear the difference and has chosen ones that turned out to measure a bit better. It is folks like him that appear to offer some evidence that these measurements even at so low a level may actually be of interest.
We are now at the fundamental level of defining what a "diode" is. You are showing IV curves with a sharp discontinuity; these are rectifying whatever way you are looking at them, therefore in my book these are diodes.
Having together "conductivity discontinuity" and "no microdiodes" is a physics contradiction, either of the two entities must be false. Pick one and forever hold your peace.
In the BT thread, in the context of contact distortions, you posted IVs with sharp discontinuities, calling them "interface distortions" and claiming there are "no microdiodes". Don't make me search too deep, you know search engines are a biatch.
You need to find it. Discontinuities are not just by diode action. Spark gaps are discontinuities but are not diode action.
I have shown that oxidizing copper conductors does not give rise to diode action.

Under certain impractical circumstances (like biasing at 25kV), a spark gap is a diode, rectifying or tunnel, depending on the metals on the two sides. It is called a metal-insulator-metal contact, and google will return lots of references on this well studied type of device. So your example doesn’t hold water. Any IV discontinuity is rectifying, no exceptions.
Copper/copper oxide is a classic example of a solid state diode, due to the band gap between the edge of the conduction band in the copper oxide and the Fermi level. That gap is called Schottky barrier.

Now you need to show that spark gaps at 25kV and rusty copper joints have any relation AT ALL with commercial resistors subject to a few mV of Audio signal and explain the gross differences claimed by the OP.
That, or save your ammo for arguments in the proper Thread ... which certainly is not THIS one.
I see more and more and more DESPERATE efforts to change subject, anywhere at all, since true believers have miserably failed in proving Post #1 claims.

I’m afraid I am the wrong tree to bark at. Barking at Ed would be much more productive, he has all kind of resistor distortions data, non rectifying IV discontinuities, cables with funny properties, secret listening tests of the above, etc… hanging on the branches. He may drop a few, to your satisfaction and my entertainment.

So do diamond resistors have a higher noise level given the multiple paths within the lattice?
I did google the electrical resistance of depleted uranium to see if if there's an audiophile market opportunity. No test data and now there's a black van parked opposite my house. 😱😀 (j/k)
Sorry, maybe I mixed the mailman with the letter author. 😱
So many arguing just for the sake of it that names crisscross all the time.
