But not all- or else there would be no specialisties and no specialists more equal than the other specialists. This example is very similar to the "training" path most audiophiles go through. At some point one with a passion for music is exposed to High End equipment for the first time. It is a revelation and he can't believe what he can hear/enjoy in the music reproduction and what he has been missing from his pedestrian system. So he now embarks on a journey to explore and learn all he can about better audio equipment. He goes to a High End dealer and compares a couple of preamps (for example). He may hear some differences but he isn't sure what he's hearing and can't verbalize what the differences are. At this point it's all very confusing. Over the next few years, he does much more equipment comparisons in audio stores, on friends' systems and on his own system until his ears are trained to hear the differences between the components and identify them reliably. He discusses the differences with fellow audiophiles where there is much agreement on what they all hear, but opinions differ on which each prefers or which is more "accurate". These debates fuel late night listening sessions. At some point, at the urging of a skeptical friend, the audiophile engages in a "blind listening test" with a couple of familiar components. Where did the audible differences he had easily identified earlier disappear to? He's back to his original state of confusion. Did the blind test filter out the differences (most likely) or had he imagined the differences he and his friends had identified (not likely). So he leaves blind testing to the rabid minority on RAHE, and proceeds to enjoy his audio/music appreciation hobby with his friends and never thinks about blind testing again. Like the cardiologists in the above example, he goes on to trust his ears rather than some questionable application of a test that acts a filter to his hearing, and finds much much enjoyment with his hobby and audiophile friends. The blind testers on the other hand, become like the general practitioners above or drop out of medicine (and audio) completely. Sound familiar? How many of you fit this profile? Regards, Mike |

A few of those become cardiologists who had better hear heart murmurs inaudible to the generality of physicians. It is their responsibility to decide whether to direct the patient for surgery or hold off for a time. Oh really' do you have some evidence that this phenomenon actually exists? What "phenomenon" are you referring to? The fact that what is heard depends on who is listening? Surely it does not need endless repetition to get throughto you. Or could it be the fact that the competence in int.medicine/cardiology is certified (Lord knows not faultlessly!) in the U.S., U.K. and Canada by a competitive exam with high failure rate after 5 to 6 years of postgraduate clinical experience? Ask your brother for details. Or the fact that in the U.K. and Canada the path to cardiac surgery leads through a cardologist's referral to a surgeon with decision reached at a joint cardiology conference? (Were this path followed everywhere and in all the divisions of elective surgery the operation rates would drop dramatically with no detriment to the patient.) It is true that in this citadel of adventurous free enterprise, the U.S., some ambitious small hospitals undertake cardiac surgery as well. I know where I'd want to end up if I needeed a little carving. Now the interesting thing to observe was that some of the med. students who couldn't hear were quite aggressive about it and accused their colleagues and their teachers of fantasising. Till the technology supplied new tools. Phonocardiogram demonstrated not just two or 3 or 4 but 6 different heart sounds. We trained and some of us began hearing more. But not all- or else there would be no specialisties and no specialists more equal than the other specialists. And:.........???? Just that Mr. Nousaine. It does not matter if you had 3 or 30 or 300 testees, including yourself. You're not testing component differences. You're testing some individuals' responses to the way some components reproduce some types of music. What we need to know is details: Are you looking for the differences in reproduction of train whistles, amplified pop, violins, cellos, clarinets or voice. Voice amplified or not? How did you select your sample? comparable age, gender, hearing, related musical experience and exposure? How big was the sample you ended up with? Detailed results. Your statistical methods? What have you done about the minority who "heard"? Did you bury it in the majority who did not hear, like your "listening tests' predecessors had done? And so on ad infinitum. I asked all this before. Could you answer this time rather than keep silent and return to the charge da capo al fine as though nothing happened in between. Let me tell you something about the real-life "listening tests". You're familiar no doubt with a very low-tech instrument called stethoscope. At an early stage in the medical school introductory lessons to clinical medicine- ie. introductory lessons to train those who will one day hold life-death issues in their hands- it becomes apparent that a few hear more and most hear less. All of them using the same technology and all of them with young,undamaged ears.. Those who hear more assume that there is even more to hear when an instructor says so. So they practice. A few of those become cardiologists who had better hear heart murmurs inaudible to the generality of physicians.

At some point one with a passion for music is exposed to High End equipment for the first time.

So he now embarks on a journey to explore and learn all he can about better audio equipment. He goes to a High End dealer and compares a couple of preamps (for example). Sure; he goes to a high-end dealer and gets a maxi-load of bull****. Other then a maxi-load of pre-suggestion what else would one expect? He may hear some differences but he isn't sure what he's hearing and can't verbalize what the differences are. At this point it's all very confusing. Not in the Salon with coaching; " well other discerning listeners report........." Over the next few years, he does much more equipment comparisons in audio stores, on friends' systems and on his own system until his ears are trained to hear the differences between the components and identify them reliably. Bull; how can his 'ears' be trained without programs that are selected to drive speakers to the limit? And how do you validate reliability? Numbers please. He discusses the differences with fellow audiophiles where there is much agreement on what they all hear, but opinions differ on which each prefers or which is more "accurate". These debates fuel late night listening sessions. Actually these sessions are excercizes in group dynamics and have zero bearing on sonic accuracy. At some point, at the urging of a skeptical friend, the audiophile engages in a "blind listening test" with a couple of familiar components. Where did the audible differences he had easily identified earlier disappear to? He's back to his original state of confusion. Did the blind test filter out the differences (most likely) or had he imagined the differences he and his friends had identified (not likely). So wy doesn't he examine the evidence before him? Are you telling us that rational people who have 'seen' the results of bias controlled tests are so STUPID they wouldignore their own ears? So he leaves blind testing to the rabid minority on RAHE, and proceeds to enjoy his audio/music appreciation hobby with his friends and never thinks about blind testing again. Oh really; otherwise than your personal case can you give me an example to the contrary? Like the cardiologists in the above example, he goes on to trust his ears rather than some questionable application of a test that acts a filter to his hearing, and finds much much enjoyment with his hobby and audiophile friends. The blind testers on the other hand, become like the general practitioners above or drop out of medicine (and audio) completely. Sound familiar? How many of you fit this profile?
