Scott W.,
if there is only DC bias, then some tens of GOhm would be the loss, for 300Ohms pairs case. Probably some erratic electrons and ions.
Gerhard was too permissive with 100MOhm. Probably climate in his neighbohood is responsible.
If you think this loss has any relevance for noise, considering the normal audio level powers... do some re-checking on this problem. Come on.
Edit: P.S: your DA stands for DF (Dielectric loss Factor)?

I would not call them BS.FWIW, my BS meter went off scale in the last three pages. For the usual suspects, do you really enjoy crashing and burning your last drops of credibility? It would be funny, if it wouldn't be sad in the first place...
More probably, this is MS (misunderstanding).
It is an instant tunneling, from one point of space to another, actually back to the same point. Which kind of tunneling? From quantum continuum, through our space, back to quantum continuum. In the QC frame, this process is instantaneous. In our space-time frame, it is variable from anything small (Plank time is the lowest limit we know today) to infinity.
In our space-time, it propagates from point to point, via exchange of "energy", whatever that is. In case of photon vs. vacuum, the exchange is perfectly balanced, unless interaction with matter occurs.
Energy is associated with wavelength, indicating that it could be something relating to correlations of number of Higgs bosons.
So, it is a propagation of quantum correlations 🙂
Like it? Useful ? Wrong? 🙂

I was using dielectric absorption here. BTW I have 1m cables for my electrometer that measure 10**15 Ohms at DC. This has become one of the can you hear -180dB effects.
If you used DA, then my explanation with corona (vacuum vs. air case) stands, and you cannot hear it in audio systems. My opinion.
His distortion could be real, but probably only by Lorenz electromechanical coupling. Simply misunderstanding.

Since when were we talking about speaker cables? I specifically stated that DA was more pronounced at high impedance's. Also, DA is not linear at all.
A coaxial cable is the very definition of a capacitor, a feed through capacitor in this case I guess. There is an enormous volume of dielectric material exposed to the signal, so the effect is multiplied over that of a capacitor. Now, if your signal is running through the cable in a high impedance circuit, you will hear the effect when compared to a cable with a much lower DA factor.
A speaker cable runs at a very low impedance, much less than an ohm. DA will not be an audible factor in this case. I said that earlier. So please read what I post before running off on a tangent with it.
As for air, it has very slightly more DA than a vacuum if it is dry. For my purposes, air and a vacuum are about equivalent unless you are talking about HV breakdown. In my circuits, high voltage breakdown isn't very likely as I generally only go up to about 600 VDC as a rule.
So from my understanding of the topic at the time Demian posted (and me), what Demian posted was not wrong. I'll give you a point about air compared to a vacuum, but I don't know what Demian was thinking about when he made the comparison.

Ionmw,
quantum mechanics is fundamentally a mathematical abstraction, dealing with massless, extensionless entities in isolation. Being intractable, any propagation medium is left out of consideration, a vacuum having no properties.

Amazing, in audiophile grifter land conflicts of interest are actually evidence of objectivity.
FWIW, my BS meter went off scale in the last three pages
Somehow I knew if I got them to talk about cables, everything else might start falling apart. I’ll be damned, we got rubber band suspension discourse
I'm prefer an accurate amplifier for listening. But more accurate amplifier need more good speaker (low distortion speaker) to sound good. Some kind of distortion like H2 dominant is really sound pleasing in a worst speaker.
I'm sensitive of distortion in high frequency than in low frequency. I will know if high frequency is not sound right in several second, but in low frequency distortion I can know it in several minutes or hours. I can accept high distortion at low frequency although I knew it, but not at high frequency.
Hi bimo,
Very true. But in the search for good sound, one generally ends up with good speakers as well as a good amplifier and everything else. A good place to start is with the speakers.

Interesting, I would think an amplifier with high LF distortions and low HF distortions would be quite a design challenge 😀.
It is simple. Electrolytic capacitor has high distortion in LF. Place electrolytic capacitor on feedback. Some electrolytic capacitors are worst.
Not always. You must never use two pole compensation (TPC, TMC, OITPC, etc). You can ask syn08 who built amplifier with THD 0,0001% at all audio frequency.
This off-topic discussion, with my personal opinion and your personal judgment and feedback are all absolutely irrelevant. Be free to have your own opinion, but I will not discuss it here further.
