Speaking of cables, my electricity distributor modernized his local network. He moved from aerial to underground cables and relocated a step down transformer. In the mean time I had a safety issue with mains at home. A corroded Neutral connection caused my trouble on 230V/400V mains
One of the quality parameter of power distribution system is source impedance, or short (prospective) circuit current.
My short circuit current was less than 100 Amps. After all modifications, the meter was reading 470 Amps.
That was a major improvement in safety and as well as in regard of the mains source impedance.
I did not hear any difference.

PRR- Urban dictionary yields some interesting results - including as mountainman bob notes the misogynistic reference.

As far as I am aware, scottjoplin is an Englishman who is living in Wales! It is likely that the only connection he has with Scotsmen is his love of FUD. 😉
I thought they were googling arsenal 😀 So I was googling arsenal and Scotland to try and work out what the feck they were on about
Actually, I did know the former, and who among us of a certain age doesn’t vaguely remember the several methodologies of enjoying the latter?
Actually, it is hard to decrease the inductance of cable. First thing is to close-space the send and return; after that it hardly gets any lower.
When we find "low impedance cable" it is usually high capacitance.
You are correct with respect to a single cable.
However, by running two zips in parallel, you can halve the inductance. Just twist each a little different, and they will not couple. This also works with 4 in parallel, L will be 1/4 of a single.
Capacitance adds directly.
You are also correct with respect to "low z being high capacitance". Nature of the beast.
I recommend no more than 4 zips in parallel. And if you really want to be careful, put a 35 ohm zobel on the end. That will prevent the cable from going capacitive on the amp if the speaker unloads before the amp's unity gain freq.
But honestly, I would try an imaging test with 4 zips on one speaker, one zip on the other, both connected to one amplifier channel. If you still hear a perfectly centered image, then the speaker cable is not capable of making a difference and you need to move on.. Your money will be better spent on something other than speaker cables.

Most hi end preamps that have tone control have bypass mode. But most don't have tone control in the first place.
I doubt it will be audible though.
You recognizing cables do not alter sound?
I thought you were here just to champion for the opposite view 😕
At least relative to certain brand and maker ones 😎
One of the most significant issues I worry about it the bolted fault current for equipment here. For industrial power delivery, it's caveat emptor. For residential, there is a specification to be met. 10,000 amps bolted fault is the current requirement for breakers, 100K for the panel..
Quite honestly, I do not care.
I am here to support all with respect to the E/M stuff. The L/C thingy, yah I understand that. I point out what I understand..it is what it is....

Much easier to twist a knob than swap between multi-thousand dollar speaker cables with magic boxes on them that do unknown things.

Yes cables do make a difference but twisting them most likely won't make an audible difference.
I guess if we don't care then there is no point of trying different things to make an audible difference.
I doubt it.
This is my single post in this thread. Cutting and pasting, with some appropriate tweaks, from a post I have made on two previous threads started by the OP:
Guys -an observation:
Beware this thread. You are being baited into a worthless debate by an OP who makes a practice of this kind of thing. Around 18 months ago, he was whiling away his time in a thread essentially trying to claim AC is not alternating; that all electrical circuits without exception are created based on Spice models (including those that were created before electronic computers even existed), and that a given loudspeaker crossover will behave differently if a series component were placed in the nominal positive or negative leg (no changes to electrical component order, and independent of external influences e.g. mutual inductance interactions). No support, no evidence, just hand-waving twaddle and a rapid exit when pressed for his claimed evidence, with the parting profound comment 'I prefer porn'.
Approximately this time last year, he initiated two threads, on 'audio' USB cables, and mains cables, respectively. In the case of the former, once he had provoked the reactions he wanted (naturally refusing to support his claims and insulting those who actually did provide technical data) he departed calling other members 'children' and that he was moving on to 'bigger and better things'. The ridiculous thread was closed by the mod team afterward, since there was little purpose in letting the troll get further satisfaction. In the latter case, the early stages of the same modus operandi that was employed on previous threads could be seen; fortunately it died out quite quickly. Here we will once again no doubt encounter linguistic variations on the following themes / phrases if this thread continues:
-'I've... read some books [titles unspecified] & it's too complex to explain'
-'I think'
-'I believe'
-'You need to prove [despite being the one making claims -a favoured inversion of this type of troll on-line, in print or in debate]'
Another favourite MO, which appears to be in action here, is that, once a thread has been baited into life, the OP vanishes, only appearing sporadically thereafter with short posts aimed at stoking the flames.
Do yourselves a favour: don't fall for it. Do not post here. Do not let him get the satisfaction. Let this thread die now before the drivel goes further.

What´s wrong with? :
I like them, I think they look really nice in a minimalist kind of way, and I bet they sound good too, as in having absolutely no sound to them at all - other than the music carried within them.
PS: Scottmoose, you deserve a public service medal.

Does this suggest that the red side of JM Fahey's figure of eight flex will impart a different sound from the black side? 😕
You mis-interpret.
I do not care if you think it is audible or not.
However, I have provided the engineering aspects to the cable inductance and capacitance, how to change the numbers as they apply to the energy delivered to the load, as well as controlled, simple, and sensitive audibility tests to determine if what was done has any affect on the sound.
Providing detailed understandings is not the same as "no point in trying".
