No one actually knows how to lculate what speaker cable they need

Mr. stevecham

This is your post:

Amps: Manley NEO 250 monoblocks
Speakers: Thiel CS2.4

I have correct speaker cables, for me, when I hear more than I’ve heard before and didn’t spend an arm and a leg to do so. Plus, the overall balance and stage are "just right."

1. The Manley NEO 250 monoblocks is tube amplification (not much of difference with Damping Factor Triode: 14.8).
2. Cable length is missing.
3. You claim: " I have correct speaker cables ". Is that a real request to get help with new cables?
4. At the time, your posts were so aggressive, that I took the liberty to be polite and ignore them.

I’ll do say, that there is a no much sense in matching a Thiel CS2.4 to a Manley NEO 250!

That is a 4 ohms speaker and goes down to 2.73 ohms at 600Hz ! with 88dB/w/m SPL. one of the most difficult to drive. 
I hope you enjoy the Manley NEO 250 1.5% THD and its 14.8 DF vs. 2.73 ohms...
In your case the cables are the last to worry about.

I love Kimber Kable (12TC). 8' pair cost $750. Chinese Kimber cost $45. Found out they have the same specs, so they sound the same. I did not have to listen to the expensive ones.

Mr. tobor007

I’m impressed you had mentioned specs. What specs of the Kimber Kable (12TC) cables is the one that you think would make it a perfect match to your system (Amp. and Speakers)?

Regarding the signal loss graph, I think that the vertical (x) should have been dB rather than m Ohms. Even then, it is a good sample of from where and why the skin effect might have came from…

Kimber always used wire counter on their products. What would do, to make their cable prevail over others? That’s right: The skin effect. As no other makes it that way, skin effect would be a good marketing argument. Is it for real? NO. But those who fall in this scheme, can bring it up on my thread as a saying to earn more points on posts.

From your post, the strongest saying is that you managed to get around with a $45 Chinese Kimber over an original for $750. Well done Sir.

It reminds me a boy who came home and say to his dad: I just saved you $2.50.

How come asks his father?

I run after a bus rather than take a ride.

Well said his dad:

Next time you better run after a taxi and save me $25.-

Mr. shadowcat2016 

Thanks for bringing it up.

As you say, I asked no money, only offered an idea and some help. All for free.

No one yet came back from a try with a fail or success, to prove me wrong nor right.

So, I will join the question: Why?
