A Good analogy is the Motor Trade.

The Oil you put in your car, You can pay over the top for highly advertised performance brands, or you could look up the Spec Numbers and Letters.
If they meet the Spec required, that is all you need; all the rest is Bull and promotion.

Liquid engineering and all that is just hype in my opinion. The same must be true with cables.

You need competant well made cables fit for the purpose and that is it.
