So when you parallel four 20 gauge individually insulated wires, that gives an equivalent wire gauge of 14awg wire, (15 amps), is the net inductance the same for both conductors?

Each of four individual wires will have higher inductance but connected in parallel most likely won't result in 1/4 of individual wire inductance (lower than inductance of solid 14 gauge wire) because they are in magnetic field of each other.  I suspect overall net inductance will end up the same as inductance of individual solid gauge 14 wire.  

Curiously, the Neardost Odin Gold cables have the same architecture. I shortened one recently to make it fit and was amazed at the complexity. Great post by the way. Thanks. 

@jea48   What I said before about 4 wires having the same inductance as equivalent 1 wire would be true if 4 wires fit in the diameter of solid 1 wire - not possible because od added insulation.  With larger overall diameter of multiple insulated strands wire inductance should be lower IMO.

I believe that he is simply wrong. Thicker wire has lower inductance.

I agree... I can’t help thinking what else he was wrong on.

@kijanki, I greatly appreciate you chiming in.

@kijanki,

Looking at the picture of the Music Cord Pro power cord then because of the way the Hot and neutral paralleled two groups of 4 insulated 20awg wires are placed around the the green insulated EGC, the inductance should/would be lower.

Technically then Michael, from Essential Sound Products, is correct in his statement in the video, the inductance is lower in his power cable.

Thanks for pointing out why the inductance should be lower. I sure didn’t know why.

 

FWIW, I have few old audioquest power cords from the 1990s constructed the same way as the Music Cord Pro power cord shown in the picture above. The only difference is the paralleled insulated solid copper wires are 18awg. Equivalent to 12awg solid copper, (20 amps). The green EGC is stranded wire. The audioquest power cords are not shielded though.
