Re: More good discussion and fascinating remniscences

"My point on the topic is still that many dielectrics do not have linear behavior, and this behavior grows more nonlinear as the stress approaches zero. "Soakage," dielectric absorption, or whatever we choose to call it, this behavior bears directly on the electrical behavior of audio IC cables insulated with such dielectrics."

I don't believe there is one "it". There are a host of things that can be happening, all different. There is dielectric saturation and dielectric hysteresis as well as dielectric absorption and they are different forms of nonlinearity. Actually, DA is modelled as a linear phenomenon, just a series of R's and C's. Magnetic material also has magnetic saturation, magnetic hysteresis, and I don't know what they call "magnetic absorption", if there's anything significant, but I doubt there's zero in all materials.

I was amazed the other day when watching on TV what happens to a frog in a super 45 Tesla magnetic field. It levitated, mid-air suspension. Apparently all materials have some amount of magnetic effect, be it paramagnetic or diamagnetic, and enough magnetic strength can actually move you across the room. But we haven't actually made a field that strong yet.

At any rate, Pease's folly is that he refuses to acknowledge there's more than just DA working on dielectrics, and that he thinks he has enough reason to determine what level of DA contamination or other dielectric effect is going to be audible.

Well, when it comes to other senses, like taste, some chemicals in drinks are not detectable nor distractable in 1000 parts per million, but some are objectionable at less than 5 parts per BILLION. To think some scope jockey without complete training in all audio detectable levels for all effects will tell me at what level of DA I'm not able to hear and there's nothing left to discuss is, well, unsupported, to be diplomatic. He can rant all he wants. He is no authority in the field of audio, and the authorities don't know much, either.
