Konnichiwa,
I did not dismiss DA as irelevant. I dd however say that with respect to the audible effects raised by applying a static field ("Bias") have nothing to do with Dielectric Absorbtion, as they do not effect it.
I would have thought to someone who is diligent about upholding the orthodoxy the implications would be blindingly obvious. Clearly not.
Here is why:
No matter how far you move the base-line the field generated by signal will overlay this and the same dielectric memory will apply (give or take a very small small shift) no matter how far the baseline is moved, as long as our dielectric does not break down.
Hence biasing the dielectric does not improve it's inherent DA in any significant way.
The best way to deal with DA in cables would be to define a current interface terminated in zero ohm load, where there is no voltage there is no DA.

I frankly don't understand at all what you're saying. You're using familiar terms in unfamiliar ways and unfamiliar terms in ways I can't penetrate. So I'll have to let this one lay where it is. When you (or anyone else) have got real data showing some sort of effect on audio signals by applying a DC field across the dielectric, by whatever mechanism, I'll be interested in seeing it.
Hi,
In the first paragraph of this webpage you'll find the actaul issue numbers of the L'Audiophile series where Mr. P. Johannet (Head of department and engineer for the French national electricity company) writes about his findings.
Whatever measurements were taken they are 100% useless, no X-Y axis anywhere and so on and so forth, yet I'd thought I'd post this nonetheless for those mastering the language and/or in posession of these issues.
Cheers,😉

Since no one else brought it up, I'll mention microphonics probably aren't a significant factor in any percieved audible difference wrought by biasing cables. Condensor mics have been running +48 VDC on the primary signal conductors at much lower audio audio levels for generations now. The phenomena is well understood and factored into the design of any decent mic cable.
Phantom power (48v) on a good cable doesn't make any audible difference. Phantom power will make a flaky cables real obvious however (crackles, pops etc).
It's taken from a German magazine, so I don't kow what they write about it. From a picture it looks like it's switchable series inductor, series resistor and Zobel. Very nicely implemented.rdf said:

This might fall into the 'not fair' class of scenarios, but I have seen tube outputs that didn't take kindly to any capacitance at high frequencies. The effect was measurable. So those switches could cause an audible difference. Disclaimer: not necessarily more accurate, just more betterer or worserer. 😉
Yes, any poorly designed amplifier at the brink of oscillation (i.e. "high end" crap) will be hugely affected by cable/load variations.
You heard it here first
I have an amazingly cracked out idea....
"No matter how far you move the base-line the field generated by signal will overlay this and the same dielectric memory will apply (give or take a very small small shift) no matter how far the baseline is moved, as long as our dielectric does not break down.

E=IR.... To have an electrical flow we must have current. If there is no voltage, there must be no resistance. The only way to achieve this would be to use superconductors. I'm not as learned as most of you in here, but i've heard due to the inductance in a loop of conductor (even superconductor) there is some resistance.
Superconductors get into some complicated physics(at least complicated to me) But it seems to me that the Ideal interconnector would be made from the ideal conductor, superconductor seems to fit that, though I have no idea what kind of problems could occur with superconductors. Has anyone thought of this yet???
Ideas please

Here's a photo of one of them opened up. Audiobility - High End Audio, Cary Audio amps and CD Players, MIT Cables. Chapman Audio Speakers. BitPerfect Multi Media Servers. Solid Drive Hidden Speakers.
They are moving towards using surface mounted components in their newest line due to lower mfg costs and a smaller package. But the components they use are VERY precisely measured which increases the mfg cost.
