Cables that measure the same but (seem?) to sound different


I have been having an extended dialogue with a certain objectivist who continues to insist to me that if two wires measure the same, in a stable acoustic environment, they must sound the same.

In response, I have told him that while I am not an engineer or in audio, I have heard differences in wires while keeping the acoustic environment static. I have told him that Robert Harley, podcasters, YouTuber's such as Tarun, Duncan Hunter and Darren Myers, Hans Beekhuyzen, Paul McGowan have all testified to extensive listening experiments where differences were palpable. My interlocutor has said that either it is the placebo effect, they're shilling for gear or clicks, or they're just deluded.

I've also pointed out that to understand listening experience, we need more than a few measurement; we also need to understand the physiology and psychological of perceptual experience, as well as the interpretation involved. Until those elements are well understood, we cannot even know what, exactly, to measure for. I've also pointed out that for this many people to be shills or delusionaries is a remote chance at best.

QUESTION: Who would you name as among the most learned people in audio, psychoacoustics, engineering, and psychology who argue for the real differences made by interconnects, etc.?

This question has been raised often on this forum, so there's really little to add. But I'll try.

First, by way of recycling a remark someone made some time ago. Until the early 20th century, science had identified four distinct taste receptors, and so four distinct tastes: salt, sweet, bitter and sour. Then a Japanese researcher identified a fifth: umami (savory). Did we taste this flavor before receptors for it were discovered by science? Undoubtedly we did. Lesson: the question of what can be "measured" depends on the state of the relevant science--and, as hilde45 (the OP) suggests a few comments above, science is continually expanding the horizons of our understanding.

That said, I remain a skeptic regarding the underlying assumptions of many of our passionate convictions as audiophiles. How our brains process sound is such a complex matter that it seems to me essentially a fetish to place so much emphasis on any single feature, especially when that feature is of marginal impact. It's not even fair to appeal to A/B/X blind testing as the gold standard for answering such questions; I think we all know that, for many aspects of our quest for the Absolute Sound, sustained listening--not just over hours, but over days, weeks, years--is necessary. After all, a given individual's capacity for critical listening changes over time. Acuity of hearing diminishes with age while one's mental catalog of past experiences with music increases; emotional sensitivity is different at different times; physiological variables are relevant (degrees of relative health; the presence or absence of intoxicants--it's a long list); acoustics vary even with the weather in the same room. Most importantly, and not under the listener's control, the quality of the original recording (or the acoustics of the venue, if the musical experience is live) is the fundamental limiting factor on everything else. Cables and interconnects are one of these many variables, and not by any means (IMO) among the more important ones.

But we're all control freaks. And we all want to make improvements to our systems for as modest an additional investment as possible. Hence, we hope to burnish our already shiny toys with "tweaks." That's perfectly understandable, even laudable. But it's also a distraction. At some point, you've got to decide what you're in this game for: the technology, and its near-miraculous abilities, or the music? A quote attributed to Alan Parsons comes to mind: "Audiophiles don't use their equipment to listen you your music. Audiophiles use your music to listen to their equipment." That stings. Too often, I find myself choosing music because is well-recorded and sounds good on my system. If I'm honest, I'm inclined even to confess that my recent taste in "music" is partly determined by what sounds good on my system--even though I've lived with music all my life, I play several instruments, my wife and daughter are accomplished musicians. That's ass backwards.
The idea of "social construction" gets a lot of bad press these days but, as hilde45's example of a monetary currency shows, "real" things with "real" consequences can still be matters of social construction. The placebo effect is also real, at least insofar as the belief that a drug (for instance) will have an effect often can produce that effect. It's a common misunderstanding to suppose that this means the effect is NOT "real," but rather "all in the head." It is in the head that "reality" is experienced, after all! What's particularly fascinating to me is the extent to which certain theories in quantum physics seem to imply that consciousness is genuinely constitutive of the "external" or so-called real world. "Objectivity" and "subjectivity" are not nearly so easily distinguished as we like to think. But that's a topic far beyond the scope of an audiophile forum.
hilde45's map metaphor, and djones51's distinction between the "two systems"—"objective" measurements and "subjective" perceptions—calls to mind the Borges story "Of Exactitude in Science" (which, in its entirety, is just one paragraph long—itself a kind of pun). Borges imagines a culture that has developed cartography to such a point that their best map of a territory is the same size as the territory

If a "better" map is one that indicates greater detail, then the "best" map would be one that left out no detail at all. But that would not be a map, it would simply be a pointless duplicate of the area mapped!

The relevance of this parable here is this, I think. Even if, in some hypothetical future, science were to develop measurements to the point that no subjective perception could not be rendered "objectively," this would still not touch what's at issue here (namely, the claim that if two things—power cords, interconnects, whatever—measure the same, then they must sound the same). If neuroscience is one day able to "map" the neural connections that objectively correspond to the experience of tasting a fine Cabernet Sauvignon, that neurological correlate will capture nothing at all of the experience of tasting that fine wine. We do indeed have two different "systems" here; even if there's some one-to-one correspondence that can be mapped, they are not ontologically identical, they belong to different categories of being.

And yet...although I can't have a pain in your tooth, if we are to discuss our preferences—which are strictly incommunicable, as they are grounded in our private subjective experiences—then we need some kind of common language. That's what science, and "measurements," purport to provide. I can't share the experience of my neural firings with you directly. But I can point to the objectively measurable phenomena that gave rise to them. Sure, wine tasting is "subjective," and so is music appreciation. But there are wines that command huge sums of money, just as huge sums of money are spent on power cords and cables, and we want to believe there's some "objective" justification for this other than simple taste and preference.

We want to believe this, but it may not be so. The differences between audio systems may ultimately be no more "objectively" constituted than the difference in preferences for Mozart and Black Sabbath. The same may be true of wine. On our 25th anniversary, a friend prepared a seven-course Thomas Keller dinner, I opened a 1988 Chateau Mouton-Rothchild I'd been holding for more than a decade, and our daughter took her first sip of wine. A great one to start with, no? We all waited eagerly to hear her opinion. She swirled, sniffed, tasted, and declared: "It tastes like wine." Indeed! 

One last thing. djones51 concludes by saying that "natural physical phenomena [are] oblivious to our rules, under the right conditions electricity will stop your heart whether we believe it or not." But that's so only to the extent that electricity is obeying our rules—in this case, the rules that govern how the heart operates and how electrical current interacts with that operation. You may want to say that these are genuinely "objective" facts, but to the extent that they are observed, named, measured—in short, experienced—they, too, are grounded in subjectivity, what philosophers call "mind." Kant argues that space and time themselves are features of mind—"forms of sensibility," to be specific—and do not exist except in consciousness. In the last analysis, "objectivity" is really only universal subjectivity: what is "true for everyone" is merely that which everyone will experience in relevantly similar ways.

Now, while we don't all experience Mozart (or Black Sabbath) in relevantly similar ways, we do all experience sound waves according to the laws of acoustics and auditory perception. This is why many audiophiles insist that all music will sound better on a better system (although it is also true, of course, that, for instance, bass-heavy music will sound best on a system with especially strong bass, etc.). The laws of physics don't make the judgments of taste which a musical preference presupposes. What the audio system does, more or less well (and this should be measurable) is to reproduce the aural phenomena, governed by the laws of physics, that the recording technology committed to the original source. Are these laws also "subjective"? Well, yes, at least in so far as they depend on consciousness. But they are "universally subjective" in a way that taste is not. Science gets better and better at identifying, describing and quantifying what is universally subjective, and so, in principle the audible differences between interconnects must be "measurable," even if not yet, if they exist at all. But those still hypothetical measurements no more guarantee an agreement in preference than would a comparative chemical analysis of Chateau Mouton-Rothchild and Chateau Lafite-Rothchild.

In the last analysis, Mozart, Black Sabbath, Chateau Mouton-Rothchild and the sound the wind makes in the chimney are "enjoyable" and "valuable" only if some consciousness values them. Value is not measurable. I prefer the Jupiter Symphony to John Cage's 4'33". But there is no "objective" justification for that preference. They're both objectively "aural phenomena," governed by exactly the same laws.

hilde45:

Your contrast between a film critic's qualitative analysis and a scientific, quantitative account (e.g., of the number of frames in a film) is very clever, and telling here. "Qualitative" and "quantitative" roughly correspond to my distinction between "subjective" and "objective," respectively; they're different descriptions of the same phenomenon, and not reducible one to another (whichever way one might want to work the reduction). But only roughly. Again, if Kant is right, even quantitative analysis is ultimately "subjective," even if "universally" so, since arithmetic is nothing more than an analysis of the subjective "form of sensibility" that we experience as time.

Your reference to Wittgenstein picked up on my "I can't have a pain in your tooth" trope, which comes from him. FWIW, I have my problems with the private language argument, but that's certainly not grist for this particular mill.

Still, the relevance of serious philosophy to "audiophilia" and its various debates is pretty surprising. Or maybe not. Depends on your attitude to philosophy, I guess.
