You've left out one further, vital point. "And when I tried again, and other people tried, it happened again. Every time." True in the larger picture, but the context was scientific papers. That's where science differs from superstition and religion. The miracle needs to work every time. Agreed. Somehow, there's always a reason why it doesn't. ;-) |

. .. Science can provide a lot of information: it can tell you what pollutants are emitted from the plant, and what their physiological effect is, and it can predict the number of deaths (given enough data about similar installations in the past). It can also make a stab at predicting how much economic good will result from the factory, and how much the standard of living will rise because of it, and what effect the rise in standard of living will have. Science can also tell you the economic value of the lives of the 500 children that it is proposed that we sacrifice. Yes. And should we make decisions about whom to kill based on their economic value? Or the fact that one of them just might be the next Louis Armstrong, or might do something kind and loving for someone that changes their life? In short, it can provide the pliuses and minuses of building the factory. It can tell you what the effects will be, good and bad. But it can't tell you whether to build the factory, because the decision -- once you know the facts -- is a *moral* decision, one based on your values system. I don't think there are many thoughtful intelligent people who seriously think that Science is that totally disconnected from morality, and vice-versa. The idea that science and morality are disconnected would be something that maybe a Hitler or Stalin would propose. They overlap and influence one another -- or should. But values decisions are rather different from scientific decisions. We have built into us notions about what is right, what is fair, that aren't strictly definable in terms of objective fact. A classic example: psychologists have done the Runaway Train test on large numbers of people with fairly consistent results. The Runaway Train test is pretty simple. Subjects are asked to imagine a train running down a track, out of control. It's heading straight for four people. You're standing by a switch; if you so choose, you can throw the switch and divert the train onto an alternate track, where it will only kill one person, a fat guy. Would you do it? Almost all respondents say yes. But what if the problem goes like this: The subjects are asked to imagine the same train, the same four people, but now the subject is standing next to the track with the fat guy. If the subject pushes the fat guy onto the track, he'll stop the train (because he's fat) and save the four people's lives. Would you do it? Almost all respondents quickly say no. What's the difference? The objective results are the same: the four people on the track live, the fat guy dies. But we draw a moral distinction between an act (throwing the switch) which passively allows the fat guy to die in order to save the four folks on the main track, and taking the active role of pushing him onto the track and killing him to save the other four. Same result, but our moral sense says they're not equivalent actions. Is business activity more important than the lives of individuals? Or not? (And it's of course complicated by the fact that business activity which improves the standard of living also saves lives.) This factory problem is one that has been worked out many times. In almost every modern case, the lives of the 500 children have the greater value. Yep, and I'd argue that's a development of morality rather than science. As a culture, we've decided to give more weight to the lives of children than in previous years. At least when the children live in our own neighborhood. We're still able to countenance the polluting factory when it's placed in somebody else's neighborhood, or country, especially if the children there look a bit different from our own kids. Another question which science can't answer -- yet: What is the nature of dark matter? I suspect, if we don't destroy ourselves, that science *will* answer that one in a few decades or maybe centuries. Right now it can't. (Of course, the answer may be that dark matter doesn't really exist. But that's looking less likely, from what I hear.) See, you made your question reasonable by including a weasel word: yet. ;-) Of course! I was answering a nonsense claim that science has all the answers *now*. I'm a great believer in the value of science. It's explained a great deal. It hasn't explained everything, yet, and there are still quite a few phenomena in audio that haven't yet been explained by good science. Rather than conclude that the phenomena therefore do not exist, my take on it is that our science is not complete. I have a certain amount of faith (no other word works here) that, given sufficient effort, these phenomena *can* be explained by scientific methods. They haven't been yet, and maybe won't be until we get some new mathematical tools, or new lab tests, or discover some more about the mechanisms by which the ear hears sound and the brain interprets it. In that sense, we may be waiting for Riemann and Lobachevsky. I don't believe in magic, and when confronted by pseudoscience my bull**** detector goes off loudly. But I also don't believe that *all* phenomena reported by audio professionals without an axe to grind are imaginary, simply because we don't *yet* have a scientific explanation for them. (Had to bring it back on-topic somehow.) Peace, Paul |

Or the fact that one of them just might be the next Louis Armstrong, AFAIK, Louis Armstrong generated quite a bit of economic value.

Some of the audible differences in capacitors, for example, are clearly due to things we can easily measure. Some seem to correlate with certain measurements, but we don't (yet) understand exactly how or why -- more work to be done. Given that, I'd guess that some of the audible differences in capacitors relate to measurements we have not yet invented. Or measurements we have invented but haven't thought of doing on capacitors yet -- for example, microphonics. Are capacitors microphonic? I don't know, but it might be worth finding out. Ditto wire.

These can both be directly measured and analyzed....the rest is all voo doo audiophool BS. Well, I have heard plenty of things that I don't yet know how to measure. That doesn't mean they can't _be_ measured, just that we haven't figured out how to do it properly. In addition, of course, we live in a world where everything is colored, and that makes a lot of equipment selection subjective. Even when you can easily measure the coloration, having a direct mapping between the measurement and the subjective impression of the sound is not always possible. Sometimes the source material affects the degree to which a given coloration is a problem, so the choices one might make with one recording are different than those that would be made with another. Not to say that this cannot be systematized and replaced with an accurate mathematical model, just that nobody has done it yet. That's what makes the world exciting. Paul Stamler writes: Or measurements we have invented but haven't thought of doing on capacitors yet -- for example, microphonics. Are capacitors microphonic? I don't know, but it might be worth finding out. Oh, man, are capacitors microphonic. It's worse in high-Z circuits... there are some microphones which use film capacitors for DC blocking between the capsule and the input stage, where the capacitor microphonics make a substantial contribution to the total output of the mike. --scott -- "C'est un Nagra.

David Correia www.Celebrationsound.com I'd think that at least part of the reason has to be a third option, present in scenario #2 which doesn't exist in #1. That being, if the 'fat guy' can be thrown on the track, could not one also choose to throw *himself* in front of the train? To me, that possibility adds another dimension which takes the equation from one of choosing to sacrifice 'one for the many' to a decision to commit murder vs. sacrifice...not merely passive vs. active. jak |

But I also don't believe that *all* phenomena reported by audio professionals without an axe to grind are imaginary, simply because we don't *yet* have a scientific explanation for them. We're not talking about calling all phenomena reported by audio professionals without an axe to grind imaginary, we're talking about a goodly collection of audio phenomina for which there is no known scientific explanation. Sure, but there's a tendency among some folks to say that because there's no known scientific explanation, the anecdotal reports must therefore be wrong (or stronger words). The most common reason why there is no scientific explanation is because there is no scientific evidence-gathering. "I modded this mic, it now sounds better to my posse" is not a very good example of scientific evidence-gathering, if you catch my drift. :-) Probably some of them are. Who knows? But I'll wager that some are not, and the scientific explanations -- like those for the nature of dark matter -- await discovery. Anybody who needs to dealve into the philosophy of science, or find a new form of matter in order to explain how a microphone works, is completely off the beam. |

Some of the audible differences in capacitors, for example, are clearly due to things we can easily measure. No, all of them. But only if they exist in the real world. Some seem to correlate with certain measurements, but we don't (yet) understand exactly how or why -- more work to be done. ??????????? Given that, I'd guess that some of the audible differences in capacitors relate to measurements we have not yet invented. Guessing ain't science. It isn't even good audio. Or measurements we have invented but haven't thought of doing on capacitors yet -- for example, microphonics. A very well understood area in general,. Are capacitors microphonic? I don't know, but it might be worth finding out. Been there, done that. The answer are, some are, most aren't. If you use the wrong cap in the wrong circuit you can tap on it, and hear it through the speakers. Ditto wire. Been there, done that. The answer is, some is, most isn't. If you make wire out of the wrong stuff, or the wrong way, you can tap on it, and hear it through the speakers. |

Try a 77DX. It's really, really touchy about load capacitance. You can tell the difference between star-quad and cable with half the shunt capacitance, even with 25 feet. --scott -- "C'est un Nagra.

Rather a sweeping generalization, the sweepingness of which gets to the heart of the philosophy of science, and its fundamental difference from religion. More specifically, no such statement can be made in science, but is often made in religion. Science is *not* a method of hammering down loose nails; it's a process for discovering which nails might be loose. Thanks, as always, Chris Hornbeck |

Good luck with the pinout, the 460B uses a DUAL opamp, not a SINGLE opamp. I can imagine the ripped up pcb when you finally figure that out. Good luck getting a LM4562 to work either. The guy that said it was a 301 is WRONG. Which I conceded and corrected. It's like watching a bunch of chimps pick up on the same mistake and repeat it without thought. Thanks. Since I've done over 200 of just this one model, there is an income for those that can offer a better product. Let's hear yours. OK, so without giving away any trade secrets, are you modifying the existing PCB and componentry, or replacing it with something completely new ? No. Cos without specifics it sounds like you are in fact making a new mic using a C460B casing - which in my view is not 'modifying' a C460B at all. It may well be a huge improvement, which is great. It may even end up better than a C480. Yes it is. Are you retaining the TL062, or whatever 2180Z0303 is, or have you found a vanilla (or an esoteric) drop-in replacement ? I found much better. It is esoteric. And (getting back to the original topic) are you using a length of magic wire that is having a profound effect on this upgrade ? Sometimes if the customer requests it. Mine do have a 1/2" piece of Kimber Black Pearls silver teflon wire. *** Unrelated comment *** It profoundly amused me that Marshall bothered to have an MXL603 Mogami Edition, based on a centimetre or so of internal cabling ! I tried them and didn't like mine so flicked them. geoff Great wire won't fix a bad design. It will reveal it. Jim Williams Audio Upgrades |

Anybody who isn't 8 forks, 8 knives, and 8 spoons short of place settings for 8 knows that we will never know everything that can be known. Just wait a while! ;-) The more relevant question, and almost any question would be more relevant, is whether we know enough about the perception of sound and how electronics affects it, to use what we currently know about electronics effectively manage the performance of microphones as we know them in the current context. The larger context is that we really don't know what microphones need to do to provide realistic reproduction. |
