The main problem with any cable, from the poorest to the most expensive, is the connectors. I think the fewer there are, the better.
It is useless to buy a superconducting cable if there is a tin section given by the soldering to the commander and a subsequent mechanical contact (even if screwed tightly), and a second mechanical contact of the connector in the pot holder of the speaker. Let's not forget that we often have the same connector on the amplifier side too (I would avoid it; better the stripped and inserted wires).
Same story in the connectors of the signal cables ... in the old turntables in fact to limit the problem by 50% the connectors were soldered directly to the internal board of the platter and came out in addition to the ground, two cables with their respective connectors on one side only ( when things were done wisely).
A gold or silver cable between two tin soldered and screwed connectors could visually represent a six lane highway where cars are free electrons to run at full speed, but this fast-flowing artery begins and ends with a narrow lane. countryside, dirt road.
Another example, perhaps even more representative, could be that of a city with a sewage system made up of enormous pipes, but near the purifier, where everything flows together, the main drain pipe is squeezed into a coca-cola straw. It goes without saying that the entire sewer system would have the performance of a coca-cola straw.
With this I do not mean that the Tin-Silver solder is such an exaggerated bottleneck, but certainly a solder of this type and the two mechanical contacts to follow (all for each connector), are already an obstacle for the flow of electrons. that arrive shipped by a simple cable of good copper, tin or Tin-Silver that is and the mechanical contacts are represented by the straw.
 So if I used a gold cable ..... platinum ... or a cable of a new material, the one that brings Superman from intergalactic space, costing one hundred thousand dollars per centimeter ..... absolutely nothing changes. , the maximum performance is always the straw.
Save your money .... and where you can strip the wires and insert them the old fashioned way; if you want the best, weld them directly inside .... IT WORKS BETTER.
Ohm's law says it ..... but unfortunately it's full of outlaws ... hahahaha

A cable, by physical definition, has the task of carrying an electrical signal through the movement of negative charges called free electrons, in our case, from the source (e.g. CD player, turntable etc.) to the user (e.g. Amplifier etc.) for SIGNAL CABLES;
from the Amplifier to the Speakers for the POWER CABLES.
The flow of electrons will be conditioned primarily by the CONDUCTIVE MATERIAL OF THE CABLE, (Eg. Gold more conductor than Copper. Copper more conductor than Steel etc.), but also by the LENGTH OF THE CABLE (The longer it will be the more resistance it will oppose), from the SECTION OF THE CABLE (the thinner it will be the more resistance it will resist), from the TEMPERATURE OF THE CABLE (the hotter it will be the more resistance it will resist) from the POSITION OF THE CABLE (the less linear it will be therefore wound in coils, the more it will generate electromagnetic fields that will increase resistance).

So in our case, the flow of electrons carrying the musical information must start from a point A and then arrive at a point B, trying to meet as little resistance as possible.
The resistance, which increases for all the causes described above, opposing the flow of electrons, causes a degradation of the musical signal because part of that electrical energy becomes thermal energy.
In simple terms, the more resistance we have, the more a small part of our electrical flow, instead of becoming sound (mechanical energy), will become heat that will be dispersed.
Having made this necessary premise, it can be said that:
starting from a good conductor (simple copper) containing the length of the cable (a few meters) which must be of an acceptable thickness (2.5 or 3mm), unrolling the latter then keeping it linearly and away from heat sources, we have the certainty that the degradation of the electrical signal from point A to point B will be negligible.
The CABLE, which must be shielded, CANNOT ADD ANYTHING TO THE SIGNAL, it can only avoid its degradation.
All the colorings on the bass, on the highs, on the mids ... are positive aspects. Let me explain:
Having ascertained that it cannot be the cable that adds, EVERYTHING YOU FEEL MORE, indicates a lower degradation of the signal from start to finish. It means that the musical information arrived intact, without losing part of the bass, midrange, etc.
In conclusion, I want to say that a few tens of euro cable is more than enough for our audiophile purposes.
When we say that a cable opens the sound, we enter the PSYCHOACOUSTICS, (attention ... in which I believe a lot).
The engineer Giussani, father of the legendary Esb series 7, conducted many experiments on PSYCHOACOUSTICS and he came to the conclusion that if you spend a lot of money on a cable, the brain with the belief that it hears better will process the sounds in a better way; because the way of processing sounds is subjective, like that of processing memories, (each one will add to the memory of the same event details and discordant nuances with respect to another individual, only for a different cerebral processing, conditioned by the mood of the moment ).
In conclusion, to hear better,
Each pocket has its own cable.

@vinilemania 

I tend to agree regarding bare cable if ones speaker binding posts allow … The one 

exception that comes to mind being High Fidelity Speaker cable where the housing 

of the terminals contain their proprietary magnet technology.

They are not just on ebay and they are made in the USA.
