Of course I'll stick on my magic meter to show this working (well a

for a much better wired roomstat.

I think I'd tend to make both speaker leads about the same length.
Propagation delay is obviouslly irrelevant, signal amplitude difference
well down in the noise, but the different effective output impedance of
the amplifier *might* affect the damping and therefore amplitude and
phase of the frequency response of the speaker in an audible way.
Probably not, but I would anyway.

I remember the start of this crap over 40 years ago.

A that thime Litz wire was very popular for various 'sound'
improvements. It was reported in ISTR HFN that a Frenchman had gone on
record that by using Litz wire between the front doorbell push and the
bell itself significantly improved the "tintinabular sonority" or the
bell when it rang.

Seems there still not all locked up yet........

Do Live and Neutral separately carry the left and right channels ?.

It was explained to me when I was a child, by one of my dad's customers,
that the inner core of coaxial cable carried the sound, and the outer
screen carried the picture. His certainty must have been challenged when
ITV started, I suppose.

"While the basic mains cables that come bundled with components do a
good job of getting it the power it needs to run, they invariably lack
the quality of materials and high-end construction that are required to
protect the integrity of the electricity, resulting in a significant
reduction in quality."

So you then replace all the wiring in the house, then street etc, with
the
same 'high quality' stuff?

And how about the mains connector on the amp etc itself?

It's laughable that the last few metres of cable would make any
discernible difference when the power comes from multiple different
sources, through all manner of connections and transformers, and have
all sorts of interference from all manner of noisy loads. It's beyond
belief, the disconnection of logic.

There *is* logic, and while it doesn't appeal to you because you can
pull it apart on technical and (to a point) common sense grounds, it
does to others.

I'd list the following variables, roughly in order that inform choice:
ability to pay, lack of technical knowledge, effective marketing,
gullibility, expectation of improved sound, vanity, and bragging rights.

It doesn't wind me up especially - people waste their money on far more
unpleasant things. In fact, bit like buying a posh car :-)

The ear actually has a rather poor memory, in absolute terms.
Add to that if you've gone to the bother of paying good money for new
leads, you do so expecting an improvement. Then things like listening
after a decent meal and perhaps drink effect how you hear things too.

Which is why the only way to really assess things like cables is by blind
testing.

Sounds reasonable to me.

It's not unreasonable to imagine that it might be so, and it's a step up
in sophistication from not imagining that it could.

Whatever the technical subject, it's quite easy to come to false
conclusions from a limited understanding. And it's much easier to lead
someone up the garden path if they have a little technical understanding
than if they have none.

In this case I think it's pretty unlikely that speaker cables' length -
unless vastly different in length, and so poorly manufactured that they
had an adverse effect on the sound anyway - would make any noticeable
difference.
