A young man returns home after a 2yr absence. Later he remarks to one of his friends, "it's amazing how much the old man has learnt in 2 yrs."
>Has anyone ever heard of 'residual resistance'?
It's closely related to 'thermal inertia'
As an evelope probagates it leaves a thermal trail
(losses in the medium)
>Do you know what makes it?
losses in the medium
>How is it normally fixed,
extremely high Q devices

I do not how it works inside wire. This described here can be measured on any connector contact, relay contact etc. Switching phenomena, on AC. The smaller signal, the worse. That means, all the connectors, snap-in connectors, relays, switches in the signal path can make a problem.
Wire has most of the problems of contacts, certainly more than most people know about.
Residual resistance is the 'resistivity' that is left when you super-cool a wire to a few degrees K.
It is composed of 4 components: impurities, vacancies, grain boundaries, and dislocations.
Are these important? What is done to minimize them?

'Hoover & Strong', ask for soft annealed. Only 99.99 silver, but that's rare enough to find as it is. Careful though, quite fragile. You get one or two sharp bends and it lets go. Other than that, it's the PCOCC Neotech silver wire. Quite a bit more expensive and jacketed with PVC, not the best thing in the world for a field to pass through. Likely just as fragile. Company name and company CC required to order it. They serve the Jewelery industry.

Good - remain ignorant. If I can at all help you further retain that ignorance, let me know. Might make my day.
Whoops, apologies, guys. Read Sy's comment about sniping (I'ma bout 6 pages behind in my reading here), and have stopped.
And specifically Wavebourn- my apologies. My excuse is that I've been hit so hard on these forums, no matter what I say or do...I tend to rarely use niceties. I simply 'slap leather', as they say in the western films.

Scott,
unless you are listening to sine waves, audio is not symmetrical.
Myrrleine, 'audio is not symmetrical' is not what he said. Read his post again. Carefully this time.

When it comes to wire, common sense would suggest that the higher the purity the better. This purity is a scientifically measured quality, it is not a subjective evaluation. The fact that some say they can hear this and others not, merely indicates to me that the difference could be small, not worth fighting over.
Just use the best wire you can get likewise with switches connectors. You will find the best is expensive so it comes down to what you can afford or are willing to spend.
Eventually you have to accept that there are real audio differences that you just can't hear.

Interestingly enough, some quite large and complex studies done by accredited universities with Nobel winning staff have conducted experiments that show that reality is actually 30% consensus in nature. And i do mean exactly what I just typed. Consensus. Reality. 30%.
The hard (the other 70%) reality being that the desire for a negative in the testing results by participants in the audio testing has serious and real bearing on the results. I kid you not.
Re: Re: Re: cable directionality
If you stay with it, and then change for let's say, one day..then change direction again.. you may find that after many days.. one direction will sound consistently better. Moving cables about also has the effect of micro-tearing/cracking the copper or conductive pathway. Since the signal has both core and skin components that involve a complex harmonic structure and where they may travel with their given delta, they try to pass through the micro stressed areas..and thus color the signal. Cables should be handled with care to maintain a broken-in in state.
Audiophiles don't like to move their cables, as they tend to need at least minimal breaking in again - this is the result of any thing like coiling (the uncoiling) or transportation.
The second suggestion of thermodynamics inherently implicates asymmetricality in matter (thus temporal) and relational aspects of change or delta. (SY will find a fair amount of irony in this comment) Lorentz gets kinda shaky there. But then again, he never had anything to do with Maxwell. 😉

TJ, my main man
I think, as with his views on politics and government, he takes a reasonable approach. Don't count things out, keep one's mind open to evidence, but insist that the quality of evidence be proportional to the unbelievability of a claim. Ben Franklin was another terrific thinker in the same mold; his investigation (and subsequent debunking) of mesmerism still stands as an outstanding document and a fine piece of experimental design and interpretation.

You should try that McTaggart book I suggested in the other thread, SY. I think you would find it intriguing.

A priceless quote from Jefferson:
"We certainly are not to deny whatever we cannot account for. A thousand phenomena present themselves daily which we cannot explain, but where facts are suggested, bearing no analogy with the laws of nature as yet known to us, their verity needs proof proportioned to their difficulty. A cautious mind will weigh well the opposition of the phenomenon to everything hitherto observed, the strength of the testimony by which it is supported and the errors and misconceptions to which even our senses are liable.

The purity is indeed scientifically measurable. Everything else you posit is anecdotal. Common sense very often is at odds with the facts.
