Um, duh?? You did note two different cables, yes? And, he pulled an old and put in a new??
Please leave the chip on the cutting floor, and off your shoulder.

The signal is still going to pass through the corrosion on the cable surface just like a signal will pass through each of two paralleled resistors of dissimilar values. The oxides may even add non linearity to the signal in it's passage.
If the termination ends of the corroded cable are burnished and clean the resistance of the surface corroded cable should still be the same as a new cable.
I don't know anything about Hawksford or his article. My reference is the late Allen Wright and his book "The SuperCables Cookbook". I'd met Allen a couple of times before I bought the book and he had good ears and he thought things out well. I had tried making my own speaker cables long before. Each conductor was a three wire Litz style braid made from surplus teflon coated silver plated copper strand. The cables sucked! They sounded zingy bright and I hated them. When I got Allen's book I set out to make some cables out of copper foil sourced from foil wound air core inductors made for speaker crossovers. I sandwiched a piece of double sticky side polypropylene tape with the foils and then added one single side sticky polypropylene tape on each outer surface and sealed the edges with the melt of a soldering gun. The cable sounded really great with my tube amps. Understand that the low series inductance and higher shunt capacitance of that cable topology may be a poor match for a solid state amplifier but may be perfect for a transformer output tube amp.
But after a couple of years the copper started to oxidize due to my imperfect seal and it seemed to me that the sound quality also diminished as the copper darkened. My next try for cable may be with single solid core silver. I've used a pure silver strand in a 3 wire braid Litz in signal wiring and interconnects with great results.
I do like silver wire but generally don't like silver plated copper cables.
OK ... we will agree to disagree. What I enjoy about a great tube amp is quite the opposite. Transparent, natural & musical
A very small proportion of the signal will pass through the area of higher resistance which is linear
You made a low Z cable, probably in the 10 to 15 ohm range. It reduces the settling time at the speaker, which will keep the high to low frequency delay spread below 10 to 20 microseconds.
The problem arises if the speaker impedance unloads at high frequency before the amp runs out of gain. Then the cable capacitance can bring the phase margin below zero, causing oscillation. A zobel at the load end will prevent that.
Sounded good at first, then as you aged, it seemed to change??? Welcome to my world...getting old..
Ps. Made some copper foil runs as well, .5 inch wide, kapton film at .001 thick with double transfer tape holding it tight. 4 ohms out to 5 uSec speeds, worked great. Problem is, if you bend it the ID copper wrinkles. I now have half inch wide copper flat braid 12 AWG equivalent. It can flex in length, so the cable really holds well.

An easy experiment to perform, why I have never seen it? Claims of tangible measurable results and no intellectual curiosity to actually do the experiment, appears here all the time. BTW there is no green copper oxide, the patina of copper is a combination of hydrated carbonate or sulfide of copper and it grows very slowly and is not particularly conductive.
In your next post your´r talking about "BS"; ask yourself isn´t you number above from the same category? 99% , really? So, easy to cite some hard evidence for it, or just a number pulled out of a hat to impress?
I understand that it might be difficult, but it is important to remember the distinction between a (maybe) perceived difference and the reported (allegdely) reasons for the difference.
Jumping to conclusion is imo often the main underlying problem, unfortunately on all sides.
If you can measure it, or offer something more than personal assurances that it happens, then that would be progress and would force a search for an explanation.Max Headroom said:
Digital cables could be directional, although if correctly used this is unlikely to damage the signal. USB seems to be able to transfer data reliably, and it would be unwise to rely on it for timing - although many seem to do exactly this.
How long was this cable? If a few metres then it can't make a difference. If 100's of metres then it might. The L-R signal is right in the frequency region where the cable is transitioning from being a piece of wire with resistance and capacitance to being an RF transmission line.YouAgain said:
Don't forget that these are systems. It may be the interaction among parts is even harder to contemplate than the effect of materials in the cable itself.

Shakespeare...one of the most famous audiophiles of all time. Loved listening to his CD collection while writing sonnets. It is rumoured that "Measure for Measure" and "Much Ado About Nothing" may have been inspired by his occasional visits to DiyAudio.com.
Yeah I know, i'm workin' on it, that and a bunch of other observations/effects..
According to conventional theory as I understand it, a uniform cable with correctly matching connectors should exhibit no directional effects regardless of amplitude, frequency and core/braid current ratio caused by alternative neutral/earth return paths.
Curiously however in practice I find this not to be entirely true upon reasonably rigorous (subjective) examination in multiple scenarios including spdif and analog interconnect application.
Agreed with OP, that last composite stereo signal patch cable can make interesting difference, been there done that.

They have their place in musical instrument amplifiers and in big transmitters. They have no place whatsoever in high quality audio:
They're naturally noisy and non-linear. Steps can be taken to improve linearity and frequency response - most notably large amounts of negative feedback - but no valve amplifier is ever going to perform as well as even a cheap and simple transistor one.
Having said that, I prefer to play my guitar through my venerable Vox AC30. It sounds good that way - with the huge amounts of second distortion introduced by every stage!
Incidentally, my views are in no way "extreme" - they're simply a statement of fact, rather than "views"!
That's what most people with extreme views claim - that their opinions are facts - ironic 😉
Which of those is a fact and which is an opinion? Plenty of valve lovers here it's not a fact to them. I don't mind them a bit BTW.
Finally a logical reason to trade it all in for class D...it's the newest and therefore the best thing.
