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

Mr. stevecham

1.        Let's check what the threshold of our audible ability is. The Hi-Fi STD used to be -3dB which is half the amplitude. That’s a lot.

On personal tests with a 1/9 DSP octave parametric EQ the threshold was at -0.5dB.

A 0.1% in tolerance converted into decibels is -0.00869dB. No way you hear that.

2.       Conductivity is 1/resistivity. Conductivity is measured in SI, Resistivity in Ohm.

A resistor of 0.1 ohm has a conductivity of 10 SI.

3.       When you get a 0 AWG cable, that has a 0.1% loss due to none purity dos not equals to a 14 AWG that has a resistance of 2.52 Ohms per 1000m, vs. a 0 AWG that has a resistance of 0.093 ohms per 1000m. This ratio is of x27 times or 2,700% (not 0.1%)!

So far, those who gave it a try, say I'm right. What would be your explanation to that, with your theory…? (At a time you have no idea what is my formula!)

 

Mr. mitch2

You kind of have a point.

Some get hysteric about 0.999% purity in cooper wire vs. a 0.9999%! At a time some way bigger issues are hidden below the cover of our equipment.

None is treated for directionality, cryogenic, skin effect or high purity cooper. They are all standard wires and PCBs.

Most so called hi-end cables, pretentiously use superior materials and look are practically poor conductors for the task of most amplifiers (thin wires). Those are not a match and never been calculated for the task. My idea, of having the optimum conductor (calculated) from materials that are not so pretentious or superior (by purity or any other crap), do the job and get fantastic results. It is time to weak up and faces this reality.

Mr. b4icu,

I cannot believe we are having this discussion. This is not real world. Tell me exactly, please, who, in the reality I live in, uses 1000m of speaker wire? An aircraft carrier? If there are audiophiles on such ships, then they are your market. Go get 'em.

And...even if say for the sake of argument, someone uses 10m of these wires, then that is:

0.0252 Ohm for 10 m of 14 AWG
0.00093 Ohm for 10 m of 0 AWG

Who cares? You CANNOT hear any sonic differences due to this resistance difference alone! Electrically, this is chasing angels on a pinhead when it comes to an AC audio signal of a few volts, if that.

I'm sorry but this is biggest bag of (Maritime51 please insert here) ever concocted.
