Re: Audiophoolery. 'Cable Break In' - I never knew that!
True, but even a hi fi amplifier with a bent frequency response is, in the general case, operating in its linear region, that is under the control of NFB. This is not the case with an overdriven guitar amplifier, so the sound is much more susceptible to the foibles of the individual active device.

I am currently in discussion with someone on another forum who, it has turned out, sells 'directional' cables. I suggested that he studies undergraduate physics in order to understand how wires actually work. His response was that this does not answer his questions, that it does not go deep enough, and Maxwell's equations are "old tech". Quote:
A few years earlier I was doing an MSc. A few weeks before the exams we had lots of revision lectures, in which we were reminded what had been taught in each module. In some cases these seemed to sail somewhat too close to dropping hints about what questions we might be asked. I don't recall such lectures even taking place 30 years earlier when I was an undergraduate; we were expected to do our own revision from our own lecture notes. Can I thank the forum moderators for allowing this thread to continue so we can all let off some steam? |

At the risk of causing even more distress, I heard reports from this year's Munich High-End audio show that this company https://www.schnerzinger.com/ has now released cables whose behaviour is managed not (or maybe 'not only') by passive elements but by an active system. So the cables now have, among other things, their own mains cables. I haven't yet heard of anyone suggesting that upgrading the cable's mains cable to a 'better' one can make a difference. But I fear it's only a matter of time ... Cheers, GJ

Re: Audiophoolery. 'Cable Break In' - I never knew that!
Even a brief dip into the murky water suggests that they are adept at talking about sound transmission issues which undoubtedly affect the way something is heard then seguing into cable transmission whilst neglecting the completely different time delays involved. Sound travels at about 1ft/mS but signals in a cable run around a million times faster at 1ft/nS.
Applied to their own statement that a few cm positional error is significant in sound source placement it would seem that logically cables would need to differ in length by a few tens of kilometres to have the same effect!

Re: Audiophoolery. 'Cable Break In' - I never knew that!
Apparently, it's down to the direction in which the wire is cold-drawn, which affects the grain structure (OK), resulting in a directional resistance characteristic (well, possibly, but no evidence offered), which in turn directs noise signals to earth (!).

Re: Audiophoolery. 'Cable Break In' - I never knew that!
A passive mechanism which can discriminate between a wanted signal and noise is surely worth investigating? Just think of the benefits to instrumentation, communications, medical electronics, space travel.... oh the list is endless
....Or maybe the concept has remained untouched after all these years because there is quite simply nothing to it Steve.

A 50Hz or audio-frequency circulator could be quite large....

Re: Audiophoolery. 'Cable Break In' - I never knew that!
I could do with a little "SCHNERZINGER® ATOMIC BONDING" to help repair my sash windows. Guess I'll have to stick with PVA.
I would suggest that there is an opportunity to sue these companies for misrepresentation but as they probably haven't sold anything it wouldn't be worth it. Last edited by PJL; 18th Oct 2017 at 3:37 pm. |

Re: Audiophoolery. 'Cable Break In' - I never knew that!
Blimey! "The Beat Goes On" [Now who had a hit with that?] It wasn't very High Fi like a lot of the best stuff designed to be cranked out via a Juke Box or domestic radio?]. I share David's disappointment in the lack of interest apparently demonstrated in digging deep about almost anything [past, present or future] that isn't frivilous these days but some of that is the media effect and it certainly doesn't keep me up at night. Yes everyone has certainly had a chance to ventilate but why wipe out all that effort or stop an interesting thread that's highlighting some related issue's we might not have even known were there? That's getting a bit close to book burning or 1984 for me. I wish more of the threads could have been kept.
To be honest I've never been comfortable with the "phool" term. There's too much useful overlap to make enemies. I'm quite capable of wading in myself but it's always better to shake the hand of someone you think is talking nonsense and leave them with a reassuring [not] comment like "Well you're a braver man than me." I'm sure the chap I mentioned in the Tesla thread yesterday [who met Eric Laithwaite] thought some of my views questionable but I wouldn't have wanted to miss the interesting conversation that we had, completely at random. If I'd not mentioned Trams I would never had known he was an electrical engineer! Dave W |

Don't delete this thread, that would be the antithesis of science "we don't like it, exterminate". IF cables are directional the supporting evidence would be very useful. As Isaac Newton said "we all stand on the shoulders of giants". I am quite prepared to accept evidence, real, engineering, scientific, evidence that directionality and break in do exist, until then I will stick to what we know, and use to good effect now. All we need is proof, repeatable proof. |

Re: Audiophoolery. 'Cable Break In' - I never knew that!
Something got mixed up in the quotes. It wasn't me who linked to Schnerzinger.
The sad thing about all this is that it is not possible to come up with an audio product (plus accompanying 'explanation') which is so silly that nobody will buy it. In fact, silliness and high price seem to be good selling points in some markets. |

There must be a little bit of resistance wire in there..... 14gauge copper straight through would only be about 6milliohms. They could be meter shunts, I suppose.

What does that 0.25 ohm resistor achieve? Anything at all??
