And where is your evidence that the differences your writers report -- often in terms not at all *subtle* -- are anything other than faith-based? You can't argue for science on the one hand, sir, and then ignore it on the other. At least, in anywhere else but audiophile-land you can't. It's not about evidence, its about opinions and preferences. How can you prefer the sound of something that doesn't sound different from what you have? This IS NOT a scientific endeavor. But it is, you just don't recognize it. The science of psychology is at work during sighted comparisons. It's also at work when listening blind but in a different way. However, one may feel free to point out errors in the science of objectivisits, not that the science is particularly relevant. Of course it's relevant, wthout the science there's no audio equipment. The discussion is regarding consumer choices. Without scinece there's no knowledge of what is audible in the forst place and how wide the bandwidth should be. Without science, there's no improvement in speaker technology, stylus technology, tube technology or any other aspect of audio. It's no surprise that science is applied to what influences how we hear. Not by the consumer, in making purchasing decisions. Only because of the terror on the part of dealers and manufacturers knowing what the results would be. If there were such tremenodus differences as some seem to claim, the dealers would be ramming an ABX test down your throat in order to sell those overpriced cables or whatever. |

Sounds like you are referring to yourself as the "nobody" with real-world experience with listening tests. This of course is meaningless since you've *never* been able to offer *any* proof that you've had access to any audio equipment of sufficiently high quality. And from your own published inventory of your equipment, one can conclude that it is at best mediocre enough to mask almost anything. You might as well take your minivan to the 24 hours of Le Mans. :-) All you have ever produced here, or elsewhere, are baseless claims and unsupported factoids mixed with conspiracy theories and failed attempts to mix in with a crowd that at least appears to be sane. Instead you continue to dwell among a peer group that clearly consists of the mentally ill, the perverse, the uneducable and the pitiful as evidenced by McCarty, McKelvy, Ferstler and the used bicycle salesman. The problem is, Mr. Krueger, that sensible people simply don't buy your act. That is why you have never progressed out of your basement and you never will. The only exceptions have been afforded to you by people with exceptionally big hearts, like John Atkinson, who paid to fly you to NYC to give you an opportunity to state your case and salvage something of your life's "work". John probably knew that you would once again fail but at least he'd unburden your family for a couple of days. I hate to break the news to you, Mr. Krueger, but your statement of not taking something seriously would be more consequential if it originated from the star of The Tijuana Donkey Show. The donkey, that is. Margaret |

"Clyde Slick" wrote in message ... wrote in message nk.net... "Clyde Slick" wrote in message ... You haven't done ANY such tests, at any time, with any equipment comparisons, at all. And therefore I can't possibly understand that such tests are valid and that sighted listening is a waste of time in most cases? For one thing, tests using other people's ears does not tell you what YOU will experience. Since human hearing doesn't really vary that much, a bias controlled comparison would give me a much better idea about a piece of equipment than a sighted non-bias controlled comprison. The reason I haven't done anything other than some cursory blind comparisons is because I know what I know about audio equipment. Like I said, DBT's don't do a thing to remove the bias of sameness, so you might as well not participate in such flawed medium. I can sympathize with your plight. None needed since I don't worry about sameness. I'm looking for sameness insofar as the sound of the equipment should not have any sonic signature. I want it to be transparent and not add anything in the way of audible distortion or noise. I want it to be able to drive a normal speaker load, and do so at volume levels that I enjoy. If I don't like the sound of a particular recording, then can feel free to use other means to distort it into something I do like the sound of. I'm not looking to distort everything, since my goal is accurate playback of the recordings so I can tell what was intended by the artist and engineering people who hopefully treated it as a labor of love. I have no problem with people fine tuning things so they get what they consider to be a "musical" sound, I just want to start from a point of as accurate as possible before I add or subtract anything from what was recorded. To that end I learn as much about what is audible and what is not so I don't end up with anything less than the best, most accurate presentation possible. |

Thanks George for admitting you have no purpose on RAO other than to distort the words of people with whom you don't agree. Since I do know what a good stereo sounds like having been actively involved in audio since 1972 and hearing systems from scores of manufacturers, probably several times more than most people, I have a very godd idea what good stereo sounds like and how to get one. |

I don't know what house of cards that would be, since I make my audio choices on the best, most reliable infomation I can get. The only reason I've not done any ABX testing is because I'm in a position that most people aren't. I get informationthat is real world and tells me how a device is going to perform. I know what the FR is and how much if any deviation from flat there will be. If that's a house of cards to you, then so be it. It IS, because I happen to think it's important to actually AUDITION something before I buy it, or even comment on it to others. That's unfortunate, since you are saying you actually have to hear crap to know it's crap, you must waste an awful lot of time. |

That's fine for you and us other Normals, but Mickey is handicapped by not being able to distinguish good sound from bad using only his own brain. That's why he has to resort to specs. More distortions George? Sheesh, I have never said I don't audition equipment other than CD players. Everything else I hear before I buy. I find a place that has stuff I'm interested in, I listen to it, sometimes through my own speakers if it's a place where I've built up a good rapport with management. Then I get the full set of real world performance facts about whatever it is I'm considering and when I find something that can perform to my standards, accuracy with no sonic signature of its own, then I buy it. This seems to be a pattern with the 'borgs. Their class envy is reinforced by their inability to hear the finer points of audio reproduction. So They react to Their own failure by attempting to drag all the Normals down to Their level of deafness. Sad, really. The only pattern is that you and those like you who are afraid of people finding out how much similarity there is in audio equipment, make a point ot lie and distort the facts. There is no class envy, there is only a desire for reasonableness. If people want to spend hundreds of thousands of dollars to get great sound, I'm all for it, I just hope that they're spending the bulk of that money where it actually will do the most good, on speakers. An expensive hi-fi with **** speakers is a **** hi-fi. A moderately priced system with great speakers being driven by equipment that provides accurate playback is a great sounding system. Personally I won't settle for less than the most accurate playback I can get. |

God comes out against ABX.
wrote in message oups.com... wrote: wrote in message oups.com... wrote: wrote in message oups.com... wrote: wrote in message oups.com... wrote: "ludovic mirabel" elmir2m @pacificcoast.net wrote in message ... "Robert Morein" wrote in message ... wrote in message nk.net... wrote in message ups.com... Arny Krueger wrote: wrote in message oups.com Summary: DBT and ABX have blinding in common. This post is yet another pathetic example of how clueless and logically-challenged Mirabel is. The relationship between ABX and DBT is that ABX is one of several kinds of DBTs that are used in audio. In the set called DBT tests used in audio, ABX is one of several proper subsets. Another well known subset of DBT audio tests is ABC/hr. I note with regret that instead of addressing issues you once again choose glibness. Mainly a personal (or in your own terminology "defamatory") attack. Yes, ABX is "one of several Kinds" of DBT or a "subset" of DBT. Proposed and so intended by A, Krueger. Whatever you say. Offhand I too can propose 25 more "subsets" with nice initials. The question you don't even attempt to address is "Has it been researched to validate it as a test for uncovering differences between audio components? Where? When?" You have only yourself to blame if that leaves the fatuous "slight forger" McKelvy as your spokesman. Being labled a "slight forger" by a complete idiot is hardly going to cause me to ose any sleep. By compliant silence you endorse 1) his clumsy forgeries;eg. attributing to me moronic views hatched in his simple brain 2) screaming "liar" - was it nine times?- without the slightest attempt at quoting the (nonexistant) evidence that he asserts would refute me 3) typing "DBT" into his Google "search" and copying the results here wholesale with no rhyme or reason in keeping with his reading comprehension problems. Ludo, if God himself came down from the heavens and presented you with concrete evidence of the efficacy of Audio ABX, you'd still deny it. Tellingly, God has failed to endorse ABX. It comes under idolatry. If the chapel prayed and got their wish that would be the first experimental proof of ABX validity ever. Except for all those JAES articles. ----------------------------------------------------------------------------------------- Dear slight forger Prof McKelvy. You convinced me. I know nothing about "accuracy", "audibility" and other such topics that are life blood to you. As long as the world of audio has scientists like you and Sullivan we are all audio-safe. And as long as there are people like you trying to dumb down the science of audio, the hobby will be populated with nutballs. Make your joint recommendations for the ideal system and we will all be in audio heaven for good. Or is it enough to just look up "Consumer Reports"?. With impatient anticipation Ludovic Mirabel I don't read CR. I'd probabably start by getting some bench test info on the Behringer A500 amps to see if they actually cut the mustard in terms of advertised performance vs. actual perofrmance. Assuming they live up to their claims, I'd have at least 3 of them, one to power a subwoofer, and 2 in bridged mode to power the Dynaudio speakers I'd pick. If this is to be an ideal sound system, it would have to include a top of the line turntable which would require me to learn ore about them since I haven't paid attention to them for about 20 years, but I understand VPI is still considered good along with Koetsu and a few other phono cartridges. Lexicon preamp, since they do tihngs that others don't. Sony universal CD player, or some other well built brand. The subwoofer would likley be a DIY project using Sonotube due to the smaller footprint, and the fact that it's a tube.so no problem with cabinet resonances. The driers would be from Adire Audio most likely but there are a couple other lines that I would chenck out first. Of course there is a possibility that I might wish to consider an Infinite Baffle sub, but I'd probably consult with Tom Nousaine on that since he seems to have a pretty good idea about how to get good bass. Assuming the Behringers worked out, the most expensive parts wold be the speakers and the turntable although once I had all the LP's transferred to CD, there would be little use in having one, so it would no doubt be sold off fairly soon. Not outrageous but easily capable of delivering first rate sound with plenty of clean power and lots of headroom to spare. What's yours? --------------------------------------------------------------- Surprisingly your choices are quite sane. (They must be because I own two of them.) Not surprisingly you don't mention using ABX to select them. Which ones do you think I would need to do that for? Not the speakers obviously, especially since I've heard and used enough of Dynaudio's products to know they are first rate. The amps? I chose them for the fact that they are very inexpensive and when bridged the odds of having any audible problems with distortion of any kind are unlikely. The preamp? As I said Lexicon can do thngs nobody else I know can do. The turntable? Already recognized as one of, if not the best. Koetsu also recognized as first rate, but all phono cartridges are a crapshoot. You don't even claim that your "scientific" choice is superior to others who just listen. Since it is such a good tool for uncovering "subtle" differences (what a cretinous term!- subtle to you , gross to someone else and of no interest whatsoever to Joe the public) Subtle means not overtly obvious. If it's gross it would be to anyone with reasonable hearing. I guess that you're convinced that your choices are the one and only, without any possible competition; and no need to check by ABX. As I said I don't know anything about the amps and possibly might not find them good enough, but in bridged mode I figure that's unlikely. Dynaudio make the best speakers I've ever heard, without question. Their drivers show up in virtually every other speaker system I've ever liked, though Scan Speak drivers are a close second. Listen to the VSM Merlins. They use Dynaudio tweeters and SS midbass drivers and sound amazing for the size even if they are IMO overpriced. I envy you your self-assurance Prof.- it should move mountains- or at least RAO. It's the confidence borne from knowing how stuff works. But since you managed to arrive at your ideal system just by using information available to everyone else why do you keep fighting the good ABX cause for everyone else but you? I'm aware of the fact that ABX is one of the reasons these products sound and perform as well as they do. I'm aware of the fact that amps like the Behringer, if their specs are to be believed should produce sound that is clean and clear and indistinguishable from any other SS amp that is designed for accurate sound. Would you like me to ask you to "prove" your choices by a "bias-free" test like your chapel co-morons keep asking Atkinson or anyone else who says that he likes this better than that. In fact why not - prove them. Prove that Koetsu is superior to the top Grado and that a Sonotube woofer is better than top Electrovoice. Prove it in "a bias-free ABX test". With some bets on the side? Should be easy: cartridges and speakers differ, don't they?. You have no excuse Why? I hate the sound of LP's with all that clicking and popping and the inherent distortion. I've been listening to a lot of LP's over the last few days. Playing stuff I don't already have on CD and there's no dubt I need to get the CD versions of the stuff I've been listening to. Please don't even try to cover up by collapsing an unproven, unvalidated, unresearched daydream like ABX with DBTs, which have been researched, validated and proven up to the hilt. Please stop trying to get people to believe that ABX is anything other than another form of DBT, or that it is not a frequently used tool for audio research. This seems to be your latest ruse. ABX is not a subset of DBTs. Yes it is. Audio ABX or any other form, is still a form of DBT. ABX as a method for comparing musical reproduction of audio components exists only as wishful thinking. You just can't stop lying, can you? Did you notice that the last "listening test" using ABX was published in 1989? What makes you believethat all ABX tests are published? Why not contact Harman and ask when the last ABX test they did was done? And that everything that they tested before that turned out to be "the same" as everything else in the given category? And that has what to do with the tests that are done but not published? Do you beleive that everybody who does an ABX test has an obligation to publish them for your benefit? When I described my own blind method I called "left-right" ( see details in my recent thread) I made it clear that I had no scientific or universal pretensions. Good, since the whole thing is laughable. I find it easier to compare things simultaneously than successively. Others may feel differently. How would you like it if I said I have another "subset" of DBTs - Mirabel's left-right.? Amused. But that's how I feel about mostof your screeds. I'd never as much as dream of claiming that because it is blind it must work - quoting double-blind research as evidence that my left-right works ---the way you do. Yet you still can't deny that ABX is used all the time by audio researchers and comapnies like Harman. All this is quite apart from your being so fanatical that you forge other people's (mine) I did not forge your name on anything. When I corresponded with Mr. Olive I did not use any names to spare you the embarassment of looking like an ass. I used your name on the thread, because it was your nonsense that I descrived to him. text in order to blacken my reputation with innocent bystanders (Sean Olive), copy titles of irrelevant articles as "proof" of ABX, lie that ABX is used by practically everyone in research without any evidence other than your say so. They are not irrelevant and the fact that you think so shows how little you know and how little you want to know. As to your reputation, you are already considered a joke amongst everybody that actually knows anything about the science of audio. I must ask like Paul Packer did. What's in it for you? Why do you keep chanting the credo for others that you don't follow yourself in your day-to-day practice? I've already explained why I have not ever used ABX for any of my choices. Should I not be able to avail myself of the kind of information I now have access to, then I would use ABX without hesitation. But then one remembers that history is full of fanatical believers- Like yourself. Ranting and raving against a research tool that has helped in many audio fields, from hearing aids to telephones and yes, consumer audio. You are fantatic in your denial. most of them going peacefully into the sunset thanks be mercy- but some following their leader's power grab; assisting in "reeducation" I'm not forcing anyone to be re-educated, I am hopefully allowing people to compare differnt approaches to decision making about their audio purchases and allowing them to see how they can make better, more reliable ones, either through ABX or another DBT, or in the same way I do it. camps, in organization of famines and wars, in collectivizing peasantry, purging the race and so on. What was there in it for them other than jackboots and a truncheon? Thanks for once again revealing what a crackpot you are. |

I find a place that has stuff I'm interested in, I listen to it, sometimes through my own speakers if it's a place where I've built up a good rapport with management. Then I get the full set of real world performance facts about whatever it is I'm considering and when I find something that can perform to my standards, accuracy with no sonic signature of its own, then I buy it. This seems to be a pattern with the 'borgs. Their class envy is reinforced by their inability to hear the finer points of audio reproduction. So They react to Their own failure by attempting to drag all the Normals down to Their level of deafness. Sad, really. The only pattern is that you and those like you who are afraid of people finding out how much similarity there is in audio equipment, make a point ot lie and distort the facts. There is no class envy, there is only a desire for reasonableness. If people want to spend hundreds of thousands of dollars to get great sound, I'm all for it, I just hope that they're spending the bulk of that money where it actually will do the most good, on speakers. An expensive hi-fi with **** speakers is a **** hi-fi. A moderately priced system with great speakers being driven by equipment that provides accurate playback is a great sounding system. Personally I won't settle for less than the most accurate playback I can get. According to your tin can measurement tools. |

ABX is not DBT's Siamese twin
wrote in message nk.net... "Clyde Slick" wrote in message ... wrote in message ink.net... Only because of the terror on the part of dealers and manufacturers knowing what the results would be. If there were such tremenodus differences as some seem to claim, the dealers would be ramming an ABX test down your throat in order to sell those overpriced cables or whatever. They wouldn't be wasting their time setting up ABX's, especially for cable Since there are no differnces in the sound of cables, they would be doing the world a service in demonstrating that fact. That is not a fact, its an opinion. My belief is that lots of cable sound more or less the same, but some may not, and the differences are not substantial enough to worry about them, especially considering the price,. But it depends on your bank account, and how much your spending on the rest of your system. Cable upgrades are fine, but super expensive (+$1,000) upgrades are a waste that can be better spent on better sounding equipment. |

"Clyde Slick" said:
To me, the best is not necessarily the most 'signal' accurate. And the measurements you use are too elementary to account for a lot of differences one might here. For example, you don't even acknowledge that the signal contains information relevant to imaging, much less do you have anything to measure that with. Some of that can be traced back to the ability of an amplifier circuit to handle small signals while at the same time processing huge signals. Also, the generation of some kinds of distortion may appear to create a huge sound stage, one of the simplest forms of which is the second harmonics distortion as can be found in some SET amplifiers. I hasten to say that this is a highly simplified explanation, because the way a signal is processed by an amplifier is dependent on many variables, like the stiffness of the power supply, the PSRR (power supply rejection ratio, a means of saying how much a given circuit is affected by its power supply voltage, or changes thereof), feedback in all its forms (local, loop around the amp, via the power supply, via ground paths, etc). Also, it is not widely known that (huge amounts of) loop feedback may introduce certain kinds of distortion, depending on (the composition and amplitude of) the drive signal, the load, and the power supply. The generated distortions in turn are fed back to the amplifier's inverting input, creating new forms of distortions that may or may not have any correlation with the original signal. Those things can be measured in some instances, in others it is kind of hard to say what and how to measure, especially when a complex signal like music is processed. Also, we're talking about sometimes very small amplitudes that are hardly measureable, and perhaps not even noticeable for our ears. The consequences of said effects may be audible however, in the form of internal blocking of an amplifier stage, at which moment the loop feedback can;t correct for it anymore. Such "spikes" can be observed with an oscilloscope of sufficient speed and, preferably, with a memory. In short, it is my opinion that an amplifier may well be responsible for (subtle) changes in "imaging", "sound staging", and more of those vague subjective terms, in spite of what most technicians want us to believe.

"Clyde Slick" wrote in message ... wrote in message link.net... "Clyde Slick" wrote in message ... wrote in message nk.net... "Clyde Slick" wrote in message ... You haven't done ANY such tests, at any time, with any equipment comparisons, at all. And therefore I can't possibly understand that such tests are valid and that sighted listening is a waste of time in most cases? For one thing, tests using other people's ears does not tell you what YOU will experience. Since human hearing doesn't really vary that much, a bias controlled comparison would give me a much better idea about a piece of equipment than a sighted non-bias controlled comprison. We are not talking sighted vs controlled, we are talking about you taking the test vs relying upon the results of other people taking the tests. What you are telling everybody here is that the ears of a conglomoration of strangers is more reliable than your own ears. No I'm not, why do say such a thing? The reason I haven't done anything other than some cursory blind comparisons is because I know what I know about audio equipment. Like I said, DBT's don't do a thing to remove the bias of sameness, so you might as well not participate in such flawed medium. I can sympathize with your plight. Yet I still manage to put together a system that never fails to get praise from the people I know who appreciate such things. None needed since I don't worry about sameness. I'm looking for sameness insofar as the sound of the equipment should not have any sonic signature. I want it to be transparent and not add anything in the way of audible distortion or noise. I want it to be able to drive a normal speaker load, and do so at volume levels that I enjoy. If I don't like the sound of a particular recording, then can feel free to use other means to distort it into something I do like the sound of. I'm not looking to distort everything, since my goal is accurate playback of the recordings so I can tell what was intended by the artist and engineering people who hopefully treated it as a labor of love. I have no problem with people fine tuning things so they get what they consider to be a "musical" sound, I just want to start from a point of as accurate as possible before I add or subtract anything from what was recorded. To that end I learn as much about what is audible and what is not so I don't end up with anything less than the best, most accurate presentation possible. To me, the best is not necessarily the most 'signal' accurate. And the measurements you use are too elementary to account for a lot of differences one might here. For example, you don't even acknowledge that the signal contains information relevant to imaging, much less do you have anything to measure that with. Imaging comes from the recording and is produced by the speakers. But then you knew that, since we've discussed it before. |

I'd ahve to check for some, but my memory is that there are something like 6 pretty regular human hearing responses. Ears pretty much function the same mechanically. Even if there are many varieties of hearing they still react the same way essentially. By that I mean that if 100 people hear a live concert and use that as a reference, then when they hear it played back, they'd still react to the most accurate one as such. I don't think I'm explaining this very well so I'll get back to you on it. |

If they want to no if there's any differnce in the sound as perceived by the listeners, then probably ABX. If they want to know which one people think sounds better thensomething else. ABX is for determining differnce, when any difference is likely to be small. Prefernce is still best done blind so that appearence and other factors don't bias the results. IIRC they have a curtain the hides the speakers, (this is dcescribed in detail at their website) they also have a knid of turntable that sets up difffernt pairs of speakers behind the curtain so they may be evaluated without any change in sound due to placement. |
