Exactly.
I should have said in my post in response to your " your ears are not my ears..." (from memory) that we all - for one reason or another - do not seek for or even require the same clues for satisfaction. Although I like a decent soundstage illusion I can get exactly the same degree of illusion from first class mono LPs as they have most of the depth and height clues (when played through a stereo speaker system) as do stereo recordings. If we are listening to the music we simply dont notice such things. A wealthy friend had a Wilson/CJ/Theta some years ago. He did not even know that for the past year the LH & RH channels were reversed!!!! Yet he went to hear every major concert in London! Nor could he stop talking about the brilliant imagery of his system.😀😀
Listen to some of the recordings made with Stravinsky conducting. He often placed the string sections center orchestra. It totally passes by most listeners - including the guy above. Many of the requirements of an audio system are as illusory as the result required by the deceived!😀
That's funny. The paper I'm reading, that's on Belden's own website, states "By the Engineering Department Belden."
Characteristic Impedance of Cables at High and Low Frequencies

Andre, think about it. Don't just parrot what's in the paper.
Basic algebra. If you say that f*L is small and can be disregarded for low freqs, the same goes for f*C. And you're back to Z0=sqrt[(R*L)/(G*C)]. As it should be. The thing with characteristic impedance is, that it is independent from freq. So if you terminate a cable with it's characteristic impedance, it looks like a resistive load, no phase shift, flat with frequency.
That paper is a load of bull.

Where are the + signs? In EQ 2. This paper was written: 'By The Engineering Department Belden'. Looks to me that it is written by Belden engineers.
Right. Funny indeed. But I stay with my conclusions. There's something seriously wrong here.
It's a basic error of mathematics to disregard a term in an equation, leave in a similar other term, and THEN conclude anything from there. Eq 2 makes it clear that Zo is constant with freq as long as C, L, R and G are constant with freq, as the author assumes. This is worrysome from an outfit like Belden.

Nice🙂 A few years ago,I was invited by two friends for coffee and some music.They also wanted some opinion on a new cartridge they were about to try.I was about 30 minutes late,and when I got there I found them enjoying their new toy.After a few minutes they asked me about my first reactions.I said,I thing one of your speakers is connected out of phase......and it was😀
Well I do, the better I can get the stage focus, the easier it is for me to notice every sound from each instrument.
+ signs? Where?
Edit: Ahhh I see, the paper SE linked to shows + signs in eq 2 between the R and G parts and the rest. This is NOT shown in the other paper Netlist linked to, which I looked at, in there is looks like just a series of multiplicative terms (although the spaces should have clued me in I guess).
OK, I take it back. Great paper!
Edit2: OK, so John, now that this is out of the way, what's this paper to do with our current cable discussion?

Yes indeed, see my previous post.
So, then, what's the issue with this paper wrt the current cable discussion?

I don't know, I just want to prove that different colored wire insulation can have different electrical characteristics. This paper shows that.
I think a good idea is those who want to try them,to agree that they will pay postages cost to the next recepient.This way,we all share the total cost.
Bud, what is the test exactly about? Are these cables to be tested whether they are different or not, or what? Sorry I lost the plot here I think.

I'd certainly have an open invite for anyone who would want to compare them blind against my orange Home Depot cables in my living room.
We tried the snake oil things with both my speakers (no difference) and some single driver speakers that Morgan Jones was demo-ing at ETF (no difference), so I'll understand if Bud is hesitant to have me do more comparisons.😀
