Speaker cables.
The common concept among audiophiles and pro audio engineers, about speaker cables iw wrong!!! (I rolled the chalang in front of R&D of MBL,
TEAC and more. None picked the glove!)
As so, also is the testing method or the provided results. They show, more than any other, what the tester would like to show: No difference.
Well the first logical question will be the difference between this cable and What?
Measuring and measuring methods would have an impact on the results.More than it's price, we need its gauge and length, and it's resistance
(even that it can be calculated from the two: gauge and length).
The speaker cables is defined as the transfer function between an Amp's output to the load (speakers).
However, the way to look on it, as an extension of the Amp's output resistance (Ro or more common name: DF=Dumping Factor).
The speaker cables is about to deliver the Amp's output signal to the speaker (an inductance lod with a moving coil in a magnetic field, and some components in it's crossover, as capacitors and more coils).
In order to do this successfully, a higher DF amp would be required. If you own a tube amp. or a low cost receiver, this is not for you.
But if the Amp's DF is above 150, or better (400, 500...1000 or D Class up to 8,000) the cable gets tricky), than the game changes dramatically.
Let's assume that we own an Amp with a DF of 400 (Ro=8/400, or 0.02 Ohms).
What is tested speaker cables resistance? What is the AWG (gauge) and length?
As no such data is provided (but it's price: $149), we can not say what it's calculated resistance (assume its made of copper).
This idea, that speaker cables should have a related (series) resistance to the Amp's Ro, would provide a formula that can calculate the ideal
speaker cable gauge, vs length. (R = ro x L (meters) / S (mm2).
So none of the suggested test by Amir or AP are to show any relevant data about the cable. It would help, as much if you would use it to fishing,
or hang some laundry to dry in the open air.
