It was clear to me. To most everyone, i should have thought.
"which is what was clearly questioned, as quoted earlier. And showing you know well how to hold a grudge, in the applause of the peanut gallery of innocents or less innocents with an agenda."
This is sick. And sickening.
Many many many people have experienced oxide effects on the sound. Contacts, wire, etc. An accurate complete technical description is appreciated but IMO not needed here. If thru trial and error we find the cause (oxide or what ever) then that is also fine with me.
Because I am interested more in results which are not "better" or different but more accurate. If you cant tell, then there is no point in any of it anyway.
If replacing a cable that is clearly heavily oxidized with a fresh clean cable and it sounds more accurate, you might assume it is the oxide and let it go at that. When, it might actually have been more a degraded dielectric (outgassing, UV, heat etc). Does it matter? To some music listeners, it does not. Just give him/her OFC wire, gold contacts and best insulation and be done with it.
Just sayin'

My drill press has no reverse, what a PITA
My friend at work recommended a tap block, in essence a u shaped block with a hole at tap body OD. I'll probably mill a 3/4 slot across a 1 by 1 aluminum bar, it will hold the tap vertical while straddling the work. Pretty much built like one of those hole depth gauges used for router work. Problem for me is, my over/under reamers are too long for my milling machine as my basement ceiling is too low...sigh. Will have to wait until my lathe plate arrives as the bed accommodates 16 inch work.
I imagine I will document the build, and put it up somewhere. Will this site ever get the gallery active again? It's been years.

If you would care to google "tapping head" you would quickly find out they don't need a reverse drill press. Most tapping heads intended for a drill press are auto reversing. How do you think I was tapping hundreds of holes in big heat sinks? You don't need to answer.
What heat sinks?
As I said, I am climbing the machining learning curve. Ed was kind enough to mention it, and I will consider it if I have the need.
"If you would care to..." Is just another way you attack others...scorpion tendency.
Had you said, " if you google tapping head" with some detail as to its salient features, it would have been viewed as a pleasant exchange. You appear to be incapable of pleasant dialogue if you have a bee up your bonnet, online is probably not the best place to have manners detailed to you.

JN,
A hand tapping gizmo is a rod to hold the tap that goes through a mounted bronze bearing to stay perpendicular to the surface below. Also reduces breakage due to tilting.
Small size tap heads to mount in a drill press ain't cheap.

And of course use Tapmagic cutting fluid.

There are Chinese clones available that (to my surprise, I have to admit) work pretty well on my small scale DIY heatsink tapping operation. They came with auto reverse, variable coupling to avoid breakage, self centering, the whole shebang for less than 1/4 the price of a Tapmatic or Procunier equivalent tool. No idea about how long they will last, but so far I am very happy with one of these.

Takes a little to adjust the drill press end stop for threading, but after that you could tap 6/32 25 aluminum heat sink holes in less than 10 minutes. It would work better on a CNC driling/milling machine, unfortunately it is too big for mine (or my CNC is too small, if you prefer), leaving no envelope for processing.

So what is the final verdict.
Does a copper cable with corroded strands sound worse?
If so, it means that a copper cable has a limited lifetime, true ?
And does it make a difference when silver plated or 100% silver strands are used?
Some effects have been mentioned like corrosion barriers between strands, preventing current to take the route of the least resistance, these barriers causing an increased Rs and Ls, but whether this has any negative impact on the sound ??
I gave it a quick try with a fresh and an old dark brown oxidized twin conductor mains cable used as LS cable, all with exactly the same number of 36 strands per leg, of the same diameter and the same 2 meter length.
Probably not the perfect LS cable but easy to compare.
Unfortunately I could hear no difference in sound.

And here we cut the tape and loop it back on itself. There was a Boston DJ that created a two hour version of "Stairway to Heaven" with clever tape cuts. It was brilliant, he played it and nothing else for an entire show one Saturday afternoon. He did the same thing with "Tusk".
So far I've found looking for square waves to be a waste of time, I can get something close but it depends on frequency and mic position, which seems to be other's findings too.
As I just read this I’m listening to ‘I’m alright’ by Kenny Loggins
Wondering which would be more mind numbing for two hours, ‘I’m alright’ or ‘Tusk’?
Wouldn’t LP be the place to tune it to, your shooting for the closest replication right?

On your old cable, did you notice corrosion at cable end-termination contact points too?
Had you tried to undo/redo the end connection of the cable to amp/speakers (that is to clear the contact points) and test for any audible difference before you move to change the cable?
Thanks

Hey George,
No corrosion on the contact end, I clean and use corrosion protector fairly regular since we live a few hundred feet from the Gulf of Mexico.
And although semi transparent I didn’t really notice it until I redid the ends one day....then found it ran the entire length. Replaced it with some decent 14awg ofc and found the difference quite surprising.....I wouldn’t wish that cca (I got mistakenly) on anyone, even on syn08! 😀

Han's,
"Unfortunately I could not hear a difference"??
Why is that unfortunate? It's just a data point.

If I’m catching what Richard was saying correctly , the better you get the square wave reproduced the better your phase relationships are.
So with dsp you should be able to ‘tune’ your measurements while watching the screen real time from LP to get the best representation......no? At least that’s how I do it by ear.
