"explain the sudible effects of ferrites round a cable?
What's to explain?
They have mu and loss and hysteresis by design and depending on their characteristics may audibly affect the audio signals if it couples into them. They are also magic bullets that can help keep crud in the environment out and crud in the box in. Proper application is everything.

"assumed that maganetic components cannot affect sound whilst a ferrite does."
I haven't assumed anything. I'm saying that believing that remnant magnetism is the mechanism that causes whatever it is that running weird waveforms and levels through a system "cures" is just an assumption. Leastwise I have yet to see any supporting data.
But I'm not saying it's wrong, merely unsupported. Don't you suppose that the magic signal could also be affecting the dielectrics or conductors, maybe even the active devices?
Rick
above titled I should have written about this earlier ?I used a hand held degausser to achieve much the same effect but for a very short term change.

The request or demand for data is a little ridiculous given that audio magazines aren't going to measure this sort of thing. NASA Is not going to get involved in esoteric audiophile concerns, nor is DARPA, MIT or Princeton. Nor are the died in the wool uber skeptics, that's for sure. And I'd eat a bug if AES or any of the other head in the clouds audio and electronics societies would touch this with a ten foot pole. :-)This is all a little reminiscent of the scene in 12 Angry Men when Lee J Cobb angrily declares, "But you can't prove it!" :-)

"The request or demand for data is a little ridiculous"
Yes, I agree that it would be so it's a good thing that I didn't do so!
It's the uncritical acceptance of speculation as truth that bothers me, it's a very dangerous trait in legal witnesses and can be a severe to dangerous one in engineering. Really it's simply no good in any realm of life.

I can see anecdotal eveidence based on a hypothesis , particularly in the absence of hard data. In addition, for us amateurs, good scientific test gear, calibrated and certified can run into major prices.
Still by diligently searching and being aware of alternate sources, it is amazing what an amateur can find. You can amass quite a store of test gear, a bit more slowly than you may desire.
For anecdotal experience, successes as well as negative results are equally important in determining the viability of a hypothesis. And of course, you need a wide pool of experimenters who are willing to share their experiences.
I find it puzzling that many so called "educated" types can not seem to grasp this concept. As an open forum, AA is ideal for this purpose as it reaches a wide range of the population. General success in a particular application, would mean to a great extent the validity of a hypothesis. In addition the queries also serve as a means of checks and balances, whereby unforeseen circumstances and applications can be discussed.
It does not serve the community any good to have one figure be an "authority" as no single man can ever think of every possibility nor try ever conceivable variation.
What evidence can you muster that any laws of science have been trampled on? Besides, the last time I looked this forum is for speculation as much as anything else. Since there is no data then it's wide open to speculation on both sides. I don't recall your offering an alternative explanation, but maybe I missed it. :-). Isn't it customary to either show how one theory is false or offer a competing theory?

Guess so, how about this one from this morning?
"But I'm not saying it's wrong, merely unsupported. Don't you suppose that the magic signal could also be affecting the dielectrics or conductors, maybe even the active devices?" -rick_m
Of course the list could be extended much further, without the burden of proof or causality we could bring in miracles, Martians, mind control, power of suggestion... anything you care to name. Not only that there is rarely if ever a single cause of anything, but there are often a few clearly dominant ones that we can wrest control of.
And this one may well involve magnetism. I just got a post from Stu reminding me that he got a similar effect using a degausser. My initial comments actually assumed that the coupling mechanism was the magnetic field but raised the question of whether the effect was due to the remanant field itself or to the mu of the material being increased by degausing thus changing the L/R ratio and hence the phase and amplitude of the reflected energy.
Rick
for the further thoughts.
In the case of degaussing software, particularly LP's, I can mesure a reduction with my gaussmeter. Here I believe the mechanism os the reaction of the vinyl with the magnetic field of the cartridge.
YMMV

Speculation IS fun, isn't it?
"Speculation IS fun, isn't it?"
YES, I love it, particularly after blank-minded observation, my specialty!
My MO for AA (and many other milieus) is to initially trust observations and ignore explanations. That sort of jelled in the mid 70's and has served me well ever since. Do you remember 'Stranger in a Strange Land'? I know, turn up the way back machine. Heinlein's notion of the 'true witness' (I think that was the name) nicely defines the ideal observer to me. Trying to rationalize and observe at the same time serves neither well.
