*WHITE PAPER* The Sound of Music - How & Why the Speaker Cable Matters

... oops, now I see your cable was 6.6uH. Not bad for my 5uH upper end estimate. However, no idea what frequency your LCR meter measures at, so it could be inaccurate at 20KHz.

The whole graph is a bit wonky. A short is 0V which is not 0db, it is some large negative number as it is log scale. If you use the "short" and offset everything else, you may have been offsetting the noise floor, not the actual measurements. You can’t say your drop was 2.1db more than a "short". That is meaningless. Hence that value of 2.1db, the so called error has no real meaning. It would have been better to have compared it to a fixed resistance or have taken a proper frequency response not a cable drop response without a proper reference.


Oh hey, in your chart, I see the ratio of the inductance of the 3 wires I said would be about 1:2:3 is actually 0.95:2.1:3.  It seems the calculations for inductance work pretty well.

Interesting reading. I have the author's Townshend F1 Fractal speaker cable in my system and it is, without a doubt, by far the best speaker cable I have heard. Good to read the science behind why it sounds so good. 

Cheap add to Townshend cables!
Some of the measurement schematics are stolen from others. They got it wrong. Mr. Townshend copied the mistakes. 
He ends up with C- capacitance. 
Capacitance is defined between two points. If the speaker cable is a joint of the black and red wires, tubed in a plastic encapsulation, there might be some  capacitance. Get two separates, no more any capacitance.
What's the big deal?
But loosing the capacitance will not change much the muddy bass, the unclean mid and highs. Getting a cable with a low resistance ref. to DF will. Garantied.

The abstract defines the "error" as the voltage drop between amplifier and speaker. Isn’t that determined solely by the resistance of the speaker and cable? So the "lowest error" would be obtained with a speaker cable of least resistance?

Look, i’m not defending  costly magic cables. I focus more on really good connections (which typically suck, and are made worse by obstinate fancy cables BTW).  I cannot tell you how many systems i have tightened a connector on or eliminated an intermittently shorting 2-guage speaker cable, or cleaned a grss set of contacts on.  sometimes after saying "this isnt right".

That said, to the above, no. Its reactance. Maybe that’s what you meant but reactance is highly dynamic and also interacts with the hugely reactive load that a speaker poses. Consider this, theoretically, when the voice coil is returning toward its original position, it is provide in back-EMF and therefore a NEGATIVE resistance.

Just saying this is not a simple "measure the ohms on our radio shack meter" sort of thing.
If Radio Shack still existed.

While I have not yet had the time to go through the ""White Paper", the reason for the change in sound may well be related to the following:

Assuming one has a Scope & a Square wave generator, try passing a 20 K HZ Square wave through a cable & Observe the waveform that comes out of the other end.

The closer the wires in a cable are to each other, the more rounded will be the Square Wave coming out of the other end.

Only way to get a matching Square Wave Out, is to space the wires some distance from each other.

As music is not composed of Square Waves, some may hear the effects of this rounding of waveform & enjoy the results; others may think that that the rounding is negative for the sound they hear.

Take your pick & use Speaker Wires that fits your preference.
