I'm still pissed I let Nutter talk me into 300 dollar Audio magic cables in 2000. Just bullshit for what we do. Mics and pre and a recorder with a nice ad stage.
That's funny. I used to have extensive conversations with him (one of my best friends who used to be a taper lived close to him in Denver), met him at Red Rocks 1996 when we each discovered our mutual love and respect for Meyer Sound Labs equipment and John Meyer (Helen too!). He tried to sell me these cables a few times, each time we would talk specifics about cables and cabling. He knew I used to co-own a small manufacturing company in Ft. Worth which dealt with high quality cabling used in oil & gas exploration with hydrophone systems. All in all, I am aware that many in this community has problems with his services, but I always thought him to have serious technical understanding of the audio world. Sure, he was making money off of it, but certainly didn't become a millionaire or anything on audio products. I found him/them to be a good source for recording gear. (now I sound like a professional suck up!)  :o

I highly recommend reading Douglas Self's Science and Subjectivism in Audio. It's published and freely available on his website, HERE, although I strongly recommend picking up a copy of his book audio power amplifier design if you're interested in this stuff. This is essentially the entire first chapter.

The most important section, in my option, is "The Subjectivists Position"

Quote

2: THE SUBJECTIVIST POSITION.
A short definition of the Subjectivist position on power amplifiers might read as follows:

  • Objective measurements of an amplifier's performance are unimportant compared with the subjective impressions received in informal listening tests. Should the two contradict the objective results may be dismissed out of hand.
  • Degradation effects exist in amplifiers that are unknown to engineering science, and are not revealed by the usual measurements.
  • Considerable latitude may be used in suggesting hypothetical mechanisms of audio impairment, such as mysterious capacitor shortcomings and subtle cable defects, without reference to the plausibility of the concept, or gathering any evidence to support it.

I believe this is a reasonable statement of the situation. Meanwhile the overwhelming majority of the public buy conventional hifi systems, ignoring the expensive and esoteric high-end sector where the debate is fiercest.
It may appear unique that a sizable part of a technical industry has set off in a direction that is quite counter to the facts; it might be felt that such a loss of direction in a scientific subject would be unprecedented. This is not so.

Parallel events that suggest themselves include the destruction of the study of genetics under Lysenko in the USSR. [1] Another possibility is the study of parapsychology, now in deep trouble because after some 100 years of investigation it has not uncovered the ghost of a repeatable phenomenon. [2] This sounds all too familiar. It could be argued that parapsychology is a poor analogy because most people would accept that there was nothing there to study in the first place, whereas nobody would assert that objective measurements and subjective sound quality have no correlation at all; one need only pick up the telephone to remind oneself what a 4kHz bandwidth and 10% or so THD sounds like.

A startlingly close parallel in the history of science is the almost-forgotten affair of Blondlot and the N- rays. [3] In 1903, Rene Blondlot, a respected French physicist, claimed to have discovered a new form of radiation he called "N- rays". This was shortly after the discovery of X-rays by Roentgen, so rays were in the air, as it were, and so was a desire to keep up with the Germans. The N-radiation was apparently mysteriously refracted by aluminium prisms; but the crucial factor was that its presence could only be shown by subjective assessment of the brightness of an electric arc allegedly affected by N-rays. No objective measurement appeared to be possible. To Blondlot, and at least fourteen of his professional colleagues, the subtle changes in brightness were real, and the French Academy published more than a hundred papers on the subject.

Unfortunately N-rays were completely imaginary, a classic product of the "experimenter-expectancy" effect. This was demonstrated by American scientist Robert Wood, who quietly pocketed the aluminium prism during a demonstration, without affecting Bondlot's recital of the results. This was widely reported by the famous reporter/explorer William Seabrook, and the N-ray industry collapsed very quickly. It was a major embarrassment at the time, but is now almost forgotten. For more on N-rays, see the new N-ray page

This demonstrates with brutal clarity that it is quite possible for large numbers of sincere people to deceive themselves when trying to perform subjective assessments of phenomena.

Answering the the USB question about clocking on a USB bus...

NRZ rules apply to USB 1.0/2.0 which is half-duplex
https://en.wikipedia.org/wiki/Non-return-to-zero

8b/10b Rules added for USB 3.0, which is full-duplex

What he said on buffer, error-correct, and re-assemble, but the bigger issues arise when buffers overrun and the data stream doesn't resend...

In a nutshell, use quality, not exotic, cable and don't exceed length for the earliest USB version of the endpoints.
Exotic cables for digital, probably most analog applications, too, is like painting your cat with cheetah spots.
It ain't gonna be bigger, tougher, or faster than the cat is was born to be.

The "open and spacious sound" of course being the wind whistling through the empty cavity between the ears of the person who bought them.

Much of this pseudoscience exists in our own end of the field.

16/44.1 is more than enough for playback (while recording at 24bit for headroom makes sense, of course).

And yet, folks here swear they can hear an improvement at 24/96 on playback.

Isn't isn't any more logical or supported by experiments using the scientific method.

Capsules: Schoeps mk41v (x2), mk22 (x2), mk3 (x2), mk21 & mk8
Cables: 2x nbob KCY, 1 pair nbob actives, GAKables 10' & 20' 6-channel snakes, Darktrain 2 & 4 channel KCY and mini xlr extensions:

There's no point buying all these expensive interconnect cables if you don't have decent speaker cables.
