Are cables really worth their high price because of their geometry?

NO !!!

The speaker cable industry, unfortunately, has no knowledge about the product they make. As so, they invented as many "Urban Legends" to Differentiate their product over others, or penetrate the market if new.

The ONLY thing that matters is the cables resistance. Resistance is a result of length and thickness. It should be way lower than the Amp’s DF.
That’s the only thing that matters.
All other:
Geometry (a new trend)
Purity (OFC)
Directional
Cryo treatment
Skin Effect
Silver over Copper
Structure
Shielding
and Snakes Oil :-)

Are all in the same ridiculous BS, spread by the industry.

Hi,
all add to pricing, research, tooling, construction, materials, marketing, justified or not. The truth is that all sound different so better listen yourself what is worth the extra cost.

B4, so that means you are an expert at cables manufacturing and you know the details of each ones processes? Somehow, I doubt it. 

Teo Audio avoided all the issues with geometry or lack of it, by going to a cable design that takes into account and utilizes a set of properties and base physics that is unique in the entire industry, and the entire world of all possible conductors -for that matter.

We created a new divide, a new separator or sorting.

On one side, is all possible cable geometries and types, and materials, companies, from Cardas to Belden, to whatever, you name it...all the many thousands of them, along with tens of thousands of design configurations and so on.......

..and then there is Teo Audio as the sole existing type, on the other.

To clarify...When it comes to dealing with the fundamental physics of conductivity, there is all cable on one side, all conductors are there ..everything you know of, all of it, no matter who or what materials, and then there is Teo Audio Liquid metal, as the singular ’other’.

Almost every single conceivable ’conductivity under high and complex signal delta’ problem you can imagine (which is what an audio signal is--it is the most brutally complex signal in the entire signal world, this audio signal thing--get educated about signal!), all banished in one fell swoop.

Go ahead, ask a physicist. Ask a multi degree transmission line specialist/PHD about this, if you think any of this is exaggerated. Ask them to tear down what I'm saying here. Good luck with that.
