I'm starting a new thread because Google "disappeared" the old one
without an answer from normally voluble A.Krueger. (It was "SACD, DVD-A...." on April 2nd .....Krueger said: "OK Mirabel I'll help you out. A reliable perceptible difference is a different that is reliably perceptible as opposed to difference that is not reliably perceptible". Why, his old reliable ABX component smoke-screen of course. He answered: "Well Mirabel you seem to have ABX on your mind. I was thinking of any of the zillions of ways that can be used to introduce the concept of reliability into listening tests. Blind testing is just one of many ways to improve the relaibilty of listening tests. ABX is just one of many means for blind testing. I hope you find this information helpful in the future." You won't get out of it shouting "zillions" Krueger. . The criteria for a reliable DBT were laid down clearly and concisely by its creators Bradford Hill and Richard Doll in the Med. Research Ccil. of U.K. I quoted those to you 3 days ago. Let me refresh your memory. The listeners' sample is representative of gender, age, social status, education and experience. They have a randomised placebo control group.(randomised means sequential in each pair-one of each) They have a rigid test protocol and employ a statistician or know enough statistics to lay down a sound statistical basis. I know that no scientific professional journal would accept any "research" not so grounded. Even if you tell them about your zillions. What experimental research can you quote Krueger to justify your claim that "ABX is one of the many means for blind testing"? We're talking about differentiating audio components. At least I am. Are you? Which professional audio journal published such research? When? Blogs on the web are not it Krueger. Till you have such experiments published your ABX is your and your clownish pseudoscientist's Sulivan toy -for use by others if so inclined. As for ABX being "just one of many means for blind testing"; yes quite; astrology is just one of many means of pursuing astronomy. I said: "He loves using terms from formal logic. How's this: "Begging the question" Krueger answers the Krueger's way: "How's this: "straw man"?" Webster says: "To beg the question- To use an argument that assumes as proved the very thing one is trying to prove." See the postscript and start trying . Krueger . So far you kept silent about it.

![]() wrote in message oups.com... Don't tell me who is a supporter of what. Just give a reference to ONE SINGLE audio component comparison by S. Olive using ABX. For that matter give a reference to ANY component comparisons by ANYBODY that appeared in an *audio professional Jornal*. This request has been repeated again and again for the last five years. So far no takers. Be the first. You have forty years of ABX to look through. Ludovic Mirabel P.S. I know Sean Olive papers because he sent them to me unasked. If thats the case...why did you so grossly misrepresent them? ScottW |

ScottW As I forecast this undead whom I showed up to be a lying ignoramus did not answer, piped discreetly down, waited a suitable interval hoping it will be all forgotten and now reemerges. You quote my misrepresentations and I'll quote yours. Quote means QUOTE not your travesty. I'll quote you OK.- it will be a pleasure Ludovic Mirabel |

oups.com Don't tell me who is a supporter of what. Right, why confuse Mirabel with mere facts? Just give a reference to ONE SINGLE audio component comparison by S. Olive using ABX. This is Mirabel's idea of proof of non-existence of DBTs: Absence of a peer-reviewed paper saying that some certain person did an ABX test of specific pieces of audio gear. What a bogus criteria! I've already explained to Mirabel that scientific papers as a rule don't involve actual commercial products, and when they do, the make and model information is often concealed. What Mirabel does not seem to get is the idea that scientific papers are about science, they not usually about consumer product testing. Mirabel also ignores the fact that Sean Olive is primarily a developer of speakers, not electronic components. Speakers generally pass ABX tests. Frankly testing speakers is not a strength of ABX testing. And this is another one of Mirabel's deceptions - he lumps all bias-controlled tests under the name "ABX". Olive is well-known for doing bias-controlled listening tests, but he generally uses testing procedures that are more suited to his area of interest - not ABX. For that matter give a reference to ANY component comparisons by ANYBODY that appeared in an *audio professional Jornal*. Asked and answered. Mirabel seems to think that audio professional journals are supposed to compete with Stereophile or Sound and Vision. This request has been repeated again and again for the last five years. So far no takers. Be the first. Asked and answered, many times. |

So far no takers. Be the first. Asked and answered, many times. Trying to match your selfimportant, pompous style Krueger I "explained to you many times" that RAO is not an audio research populariser but a voice of lay audio consumers. I also "explained to you many times" Krueger that an engineer is welcome to give such measurements as he's capable of doing at this point in time and then; if he wants to be listened to as a critic he takes off his hat and talks like another listener. His engineering school credentials make his opinions no more valid than those of a carpenter about the aesthetic effect of the Louis the XVith chair on the buyer. Till you get this into your head you'll continue to be mocked for a self-promoting, self-inflated product of an engineering school with pretences above his station. Just the introduction. Details discussed in the next posting. Ludovic Mirabel |

I've already explained to Mirabel that scientific papers as a rule don't involve actual commercial products, and when they do, the make and model information is often concealed. What Mirabel does not seem to get is the idea that scientific papers are about science, they not usually about consumer product testing. We,re talking about what S.E. Olive did Krueger; not about your ideas what he should or should not have done: S.E. Olive: "Differencews in performance and PREFERENCE of Trained versus Untrained Listeners in LOUDSPEAKER Tests: A case study"; JAES., vol.51, #9, Sept. 2003" P. 806; "The four loudspeakers used in both tests are shown in table 1" They were coded but the data were so transparent that I guessed the identity of the electrostatic one correctly (my guess confirmed by S.Olive) Krueger says in his USUAL weasely way : "...they are not USUALLY about consumer product testing". How many times Krueger do I have to "explain" to you that they are USUALLY not- except when they ARE- about consumer product testing. ABX WAS NOT USED. Mirabel also ignores the fact that Sean Olive is primarily a developer of speakers, not electronic components. Speakers generally pass ABX tests. Frankly testing speakers is not a strength of ABX testing. Now we get another weasel word; "generally" -"pass ABX tests". What exactly are you trying to say Krueger? What does "pass" mean in this context? Are you trying (very ineptly) to say that ABX is only good for testing components that do not "pass" ie "they all sound the same"? Well, we already know that. And this is another one of Mirabel's deceptions - he lumps all bias-controlled tests under the name "ABX". Olive is well-known for doing bias-controlled listening tests, but he generally uses testing procedures that are more suited to his area of interest - not ABX. Explain which areas of interest to RAO participants are "suitable for ABX.". Are there any at all? We're not psychometric researchers down here in the real world. Isn't testing of loudspeakers what you promote in your PCABX? If not say so clearly and unequivocally. We're listening.. For that matter give a reference to ANY component comparisons by ANYBODY that appeared in an *audio professional Jornal*. Asked and answered. Mirabel seems to think that audio professional journals are supposed to compete with Stereophile or Sound and Vision. Olive tested audio components under coded names. He did not use ABX. List the other coded audio component comparisons using ABX that appeared in JAES. Or say that ABX is only suitable for "science" and close off your PCABX This request has been repeated again and again for the last five years. So far no takers. Be the first. Asked and answered, many times. You're a laugh, you are Krueger Ludovic Mirabel Personal note: I sound harsh even to myself. Once anyone calls me a liar the gloves are off. This is an explanation and a warning. |
