The real problem is that the statement is fundamentally meaningless.
Which cables? Imagine a world wherein all copper conductors sound exactly the same. Still, "Cables can be distinguished" would, by your logic, be true if some cables are painted different colors or if some cables aren't made of copper. Are you suggesting that the fact you can distinguish solid copper cables from solid rubber cables is proof that you can distinguish solid copper cables from stranded copper cables? Your "logic" just doesn't mean anything. Try something along the lines of "some copper conductors can be audible distinguished." Then you might THINK you have a logically solid claim but you'd still have to to demonstrate that the distinction was made audibly and not by other means, and that it wasn't something other than copper that was being audibly distinguished (like corrosion or impurities or dielectric). And once you proved that grand hypothesis in one circumstance, then yes you could shout it from the mountaintop but you'd still have to answer questions like, "did the two conductors have radically different bulk resistance? Was there something wrong with your amplifier?" in addition to demonstrating the credibility of your tests. As for (2), I don't think you can claim objective definition of what constitutes relevant listening experience. If you haven't conducted strict double-blind level-matched difference tests then your results will be viewed as biased opinions. If you haven't conducted "subjective" (sighted) comparisons that include visual cues such as packaging and price lists, then your tests will be viewed by others as inconclusive. ulysses James Boyk wrote: Well, it's not a religious discussion. Either cables can be distinguished or they can't. The problems are-- (1) Some participants don't understand a logical point. "Cables can be distinguished" is held to be true if there exist ANY cables which in ANY circumstances can be distinguished. This is simply the meaning of the words; but it's a point which some people don't understand. To prove that "cables can NOT be distinguished," it would be necessary to prove that there are NO cables which in ANY circumstances can be told apart. (2) Most people don't have any relevant listening experience. James Boyk |

If they're not saying that, what *are* they saying; and what's the disagreement? I think they're saying (and I'm agreeing) that reasonably competent cables don't make appreciable sonic differences. That if you hear a meaningful difference between two speaker cables, then either one of them is defective, or you're deceiving yourself. That isn't really saying a lot since there's plenty of room for debate about what constitutes an "appreciable" or "meaningful" sonic difference, and what constitutes "defective" cable. I'd say that a "meaningful" difference is one that justifies the price difference between said cable and another suitable cable. I'd say defective cable is cable that has enough impedance (whether it's caused by corrosion/abuse or by design) to make a sonic impact. IF you can come up with some phenomenon other than "impedance" that changes the transfer characteristic of a cable, please present a paper at the next AES. 100 feet of 24-gage cable for some 250W speakers is "defective" cable because it's the wrong cable for the job, regardless of what kind of cable it is. When you compare that 100-ft 24ga. cable to say 3 feet of 00ga. gold-plated platinum, the difference you hear doesn't say anything about the importance of good cables, beyond what any competent engineer should already know about good old Ohm's Law. On the other hand, maybe you can measure and convince yourself you hear the difference between two brands of good, low-impedance speaker cable because one has 100 milli-ohm bulk resistance and the other has 110 milli-ohms, thereby generating a response difference of 1dB at 25kHz. If both cables are on the shelf next to each other at the store I happen to shop, and they're the same price, I might consider your suggestion on the cable. But if one cable is $0.10/ft and the other is $10/ft, I'm smart enough to stop and consider the relevance of 1dB@25kHz in a system that includes real-world speakers, real-world room, and a real-world budget. In that context, the difference is not meaningful. ulysses |

This kind of statement is extremely vulnerable to becoming part of circular reasoning. Suppose you were presented with two cables which you agreed did sound different. IF in that circumstance you would then assert that one or both cables were IPSO FACTO *not* competent, you would have converted the assertion above into a meaningless one. Saying it another way, for the assertion above to be meaningful, you must supply IN ADVANCE OF AUDITIONING a criterion for what makes a cable "reasonably competent." Something like this happened in 1970. Peter Walker, the founder of Quad, repeatedly and famously asserted that no two "well-designed amplifiers" could be told apart in blind listening, provided that neither was clipping. A careful double-blind test was carried out in which several listeners could in fact reliably distinguish some of the amplifiers. Walker accepted this result as real, but took the escape hatch of saying that making a "well-designed" amp must be harder than he'd realized, and that some of the amps must not have been well-designed, the proof being that they could be told apart. He didn't seem to realize that this was circular reasoning. The escape hatch was open to him because he'd not defined *in advance*, in a way *independent of auditioning*, what "well-designed" meant. ...I'd say defective cable is cable that has enough impedance ...to make a sonic impact. This *almost* provides the circularity I was talking about. You're saying that if it makes an impact on the sound through its impedance, it's defective. Given this definition, it's a logical IMPOSSIBILITY for any non-defective cable to affect the sound-----unless it does so through some aspect of design having nothing to do with its impedance. ...IF you can come up with some phenomenon other than "impedance" that changes the transfer characteristic of a cable, please present a paper at the next AES. This completes the circularity: You now assert that only impedance can affect the sound quality of a cable. You've now given a perfect demonstration that your assertion at the top is meaningless.

...And, of course, you would have checked to see if the response of the signal being delivered to the loudspeakers was matched within 0.2 dB over the spectrum. Why 0.2 dB? A broadband difference of 0.2 dB is adequate to make you think the louder one is better even though you can't tell it's louder. Nominally competent for any audio product is response errors no greater than +/- 0.1 dB overe the audio spectrum, clipping less than 1% of the time, noise levels that are not audible at the listening position and no operating irregularities. Will you stand by this? No back-tracking? This is your once and for all complete definition of "competent"? (Do you know about Richard Heyser's black box of many years ago that measured *perfect* on all standard tests and sounded truly awful?) ...there have been more than 2 dozen bias-controlled listening experiments that shows Walker wasn't that far from being right. "not that far from being right" = "wrong" And by the way, how many of these experiments used a live mike feed? Please cite the experiments. It simply is no one's fault but their own that the wire industry and consumer base hasn't produced a single verified experiment where wire that hasn't changed known causal factors (level, noise and frequency response) has been audibly distinguishable let alone improved sound quality. But wires *do* have different frequency responses---when in-circuit with specific amps & speakers. THat's part of what it means to be that wire. jb |

Technically, anything *could* make a difference. But you have to have priorities. I.m.o. different speaker cables, assuming they are adequate for the job (right gauge for a given length) would have the least effect of anything you could do that would affect the systems sound. Well, perhaps right after different power cords... |

Of course you're absolutely right, James, and I knew that while I was
writing it. It's a very difficult argument to state because there's so much semantic ambiguity when you're talking about subjective phenomena. I can say things like "reasonably competent speaker wire" which to me excludes a great number of inappropriate conductors and I can conclude that variance of "reasonably competent speaker wire" does not hold "meaningful" sonic consequences in any non-imaginary context. But there will always be, in opposite ends of the room, one fella who thinks .01dB at 50kHz is "meaningful" and another fella who thinks wire he pulled off of his spiral notebook is "reasonably competent speaker wire" and in tandem they will conclude I'm full of ****. In the real world, I know that I can pay a modest amount of money for any number of cables that will do what they're supposed to do, which is carry electrons from my amp to my speakers and back again without dropping too many along the way. Yes, I know that if I'm a cheapskate I'll have to choose between wire that's too skinny, too dirty, or too poorly-made and will not do the job adequately. Using the modicum of common sense I posess (whatever that is) and a little bit of experience and knowledge, I can shell out $0.75/ft instead of $0.10/ft and avoid those pitfalls. Using still more common sense, experience, and knowledge, I can decline the salesman's offer for wire that costs $3.00/ft or more (much more) if I know that the several milliohms improvement in cable impedance and the quarter-decibel frequency-dependent attenuation it prevents will be inconsequential in my control room where my transducers are set up six feet from my amplifier. So if you want to skip the lines I wrote about context and real-world equipment and budgets, yes I will concede the circularity of my reasoning. My argument states, essentially, that any cables you find that are not sonically transparent are defective for the sole reason that they're not sonically transparent. I'll stand by that statement anyway though. If you could name a specific wire that you find NOT to be "sonically transparent" but still not "defective" I'd love to hear about it. So we're clear, it's never been my position that speaker cables don't make an audible difference in sound. It's been my position that speaker cable that doesn't make an audible difference is inexpensive, readily available, and doesn't require a tremendous amount of expertise to separate from those that do. Among competent audio professionals. Now do you want to debate the definition of a competent audio professional, so I can tell you it's somebody who knows where to buy cheap, sonically transparent speaker cable? ulysses James Boyk wrote: Justin Ulysses Morse wrote: I think they're saying (and I'm agreeing) that reasonably competent cables don't make appreciable sonic differences.
