Thermal Distortion your loudspeaker most likely suffers from it. But do you care?

It is usually referred to as thermal compression—as music gets louder (more current flowing), the heating of the voice coil means that any increase in the signal level does not result in a proportionate increase in sound level because the heated wiring resists the current flow. This is the principle reason why high efficiency speakers tend to be more dynamic—far less thermal compression.

 

It’s also part of the sound of interconnects.

Not likely.
This sounds like a #metoo post where interconnects are suffering compression like speakers.
And it reads more like an advert for something not on topic nor germane to speaker compression.

 

Besides the problem of the given audio cable having it’s most perfect impedance at exactly one frequency and one frequency only.

Where all other frequencies are imperfectly handled and are converting to heat and distortion in the phase realm or time realm. smear. noise.

…

OK a 1v signal from a preamp with 600 ohms of output impedance will have < 0.002 W (If shorted).

Into a 100k ohm is almost no “work”/“power”.

 

All cables are compromises designed for the hearing of individuals with individual gear. That’s why there are so many brands and designs.

BS most cables are neutral.

 

That is part of what we complain about when we say that passive preamps are not as good as active preamps.

I found ^that^ pretty hard to believe,

The fact that the output impedance takes a thrashing at low levels is more likely the lion’s share of trouble.

The most linear of all in this area of technological challenge across all levels of loading, is the liquid metal audio cables. We’re talking a good minimum of a magnitude better, to the point that all complaints are pretty well entirely gone and people relax into realism. There is a reason that our now closed Hong Kong Distributor, who was active in and describable as the peak of the Hong Kong High end scene (no small thing, that!), called our best cables ’the biggest most important positive change in audio, of all time, in all technological areas of audio’. The only way to know if it is, or not...it is to try them out.

You distributor’s words should be that they are better than sliced bread. This is not unusual.

PS, if you ask why were’ not on everyone’ slips and in every one’s system(if we’re so dang odd, like I say, pfffft...), well it is jungle out there ....and we don’t have a million dollars to spend on advertising and reviews, so that we can make $100k on the vanishingly small group who do actually recognize and seek the best.

If the gear did all of ^that^, it would be nice.
Someone should try it.

What return policy is there?
If you can convince me, then it should get easier with less skeptical types.

===============

Back to thermal distortion of speakers, it is one of the things I look for,
The crossovers can take a thumping in addition to the speakers.

Probably the simplest example/change would be active cross overs.
Say we had a 30W amp, and if it is not clipping it is somewhere in the 1-5W RMS range. And at say 1W RMS there is typically 150 mW going to the tweeter
Now we turn up so it clips and we can get it to ~42w, and probably 20W is going to the tweeter.

So we do an active XO and the tweeter gets maybe 1W and the woofer has a bigger amp, and there is no actual passive XO to fry.

No, I don't care.  And I don't care if you care, either.  Problem solved.

There is a point (temperature wise) where equipment sounds the best. Most audiophilers don't overheat voice coils in their units. That is a problem KIDS have in sound competition. I have never had a problem with overheating parts. For me it's audiophile 101. "Protect your expensive (or inexpensive) equipment FIRST, everything else is next". I use small planars, you have to really abuse one to have them fail. If they blow I can't imagine what "that" someone's hearing is actually like. LOL no hearing insurance for that one.. Just Nose and Throat, no EARS..
