Acceptable Responses when Impossible Claims Are Made??

The theory of Relativity wasn't accepted without controversy and Einstein never was awarded a Nobel prize for that work as a consequence:

That was just the Swedes being jerks. Other top physicists, such as Planck, had no problem accepting the ideas. From the paper I referenced earlier:

Quote

The first comprehensive study of the early reception of the special theory of relativity was conducted by Stanley Goldberg; valuable historical research was also published by Arthur I. Miller and Lewis Pyenson. They found that relativity was widely discussed among leading physicists in Germany soon after the appearance of Einstein’s 1905 papers. By 1911 it was considered so well established that Arnold Sommerfeld, who had planned to speak about relativity at the Solvay Congress that year, decided to address instead the more controversial questions about quanta and the nature of light.

In terms of cables, what about Echo, NEXT, FEXT and all the other problems related to impedance, cross talk, conductor interaction and radiated EMI and RFI? Do they have no effect of how the ultimate signals sound? They certainly will effect what comes out of the end of the cable I would have thought.

None of that matters at audio frequencies.

What do you mean by audio frequencies?

With cables of lengths typical for domestic audio, the properties Blackmorec mentioned do not matter for frequencies up to 1 MHz or so. Transmission line effects only become relevant when the cable length starts approaching 1/4 of the wavelength.

@John_Atkinson and @Miska to name a few seem to agree that the performace of an ultra-wideband amplifier or of a hard-domed tweeter with a massive resonance peak may be affected by ultrasonic garbage with audible repercussions:

A speaker is not a cable.
