: : OF COURSE there is distortion in live acoustic music, including in the frequency realm. Rehearsals are designed to cure that, among other things. ok, i'm not sure I follow you here. you're using "distortion" in a way that is inconsistant with audio technology. audio techs use the term to qualify (and quantify, at times) the departure of the equipment from the original signal; in this case, the live music. so i don't understand in this case how live acoustic music (yes let's forget the electrical instruments for the moment, where distortion clearly exists but is part of the instrument's sound) has "distortion". But then, I don't believe there's any such thing as "THE sound of a piano." Correct, of course. One speaks in generalities. It is obvious that if several recordings of piano music all sound unlike a piano through a certain pair of speakers, that pair of speakers don't allow for the proper sound of a piano. Who is more familiar with the sound of a piano? ok i'm going to throw in my 2 cents here. syntax aside, an accomplished pianist is going to be able to tell you whether something sounds like a piano or not (assuming it's not a deaf accomplished pianist :-) probably more than anyone. an audio 'gearhead' is probably going to be able to describe in more technically accurate detail how a sound system is departing from the ideal, but it's not necessarily true that this person is going to "hear" better or be able to detect more quickly whether it's live or memorex[tm]. -- stealthaxe |

No. Jenn is not right. What musicians are trained to hear are gross compared to the differences between audio equipment, except between speakers or vinyl equipment (in which case, it is really largely preference).

If you can't answer that, perhaps all that you have learned from playing live music is really not that useful when it comes to understanding audio. now i'll need a new preamp :-P No you don't. |

People with experience in one specific endevour are likely to have greater skill in another endevour that is closely related in skill sets. This is not an argument, it is a claim. So far, no logic. It is not only a logical position If so, why not give the "logic"? it is often supported by evidence. "Often supported by evidence" is not good enough. For a claim to be generally accepted it has to be supported by *all* the evidence. A single counter-example, on the other hand, is enough to refute the claim. Boxers and wrestlers are usually better street fighters than the average person. This fact has been proven unfortunately in many a street fight. Basketball players usally can jump higher than average people. Well, obviously people who excel at a particular skill are likely to excell at sub-sets of that skill! High jumpers can jump higher than average people too, by golly! Amazing!! These examples are not evidence at all, so far as I can see. Math experts often make better poker players. I have seen no evidence whatsoever of this and you provide none. this can be seen by the number of poker players with advanced degrees in math now making a liing at the poker tables. I could go on and on. In fact, mathematical skill is probably a handicap at poker. A good memory and the ability to remember odds is helpful, but other skills are *much* more important. I think the logical mistakes that posters like porkygeorge make is similar to this: if all else are equal, then on average, people who are good in math may be better than others in poker, because of a better understanding of probabality. Now that is a reasonable claim. But then they extend it to a claim that "mathematicians are often better poker players". Which is a highly illogical, overly simplistic, and factually untrue claim. actually it is highley logical and factually true. The large percentage of top poker players who are highly adept at math is a fact. I have cited one such expert if you need I can name many more. But if you have some facts to support your claim that it isn't true please present them. Better yet, show me one top poker player that doesn't have a much better understanding of the odds in poker than the average Joe. Your logic is, uh, simply, amazing. Perhaps if you were able to follow it... If someone has a better understanding of the odds in poker than the average Joe, does that make that person a "math expert"? Did i say that? no. Like I said, you might be amazed at my loigc if you were able to follow it. OTOH at the risk of being redundant, if someone is a math expert it is extremely likely that they already hae a better understanding of the odds in poker than the average Joe and that will give the math expert an inherent advantage in poker over the average Joe. It will be interesting to see if this time you can follow that logic and not misrepreesent it in your interpretation. Maybe he is to you, but certainly not to the rest of us. If you were able to follow my arguments you would understand that no such position has been presented. Aperson who merely understands the odds of poker in full is at least an expert in the relevant math to poker but not neccessarily a mathe expert in genereral. here I will explain why. A working knowledge of the odds in poker would be a subset of inherent skills for a geniune math expert so it would be expected that someone with this sunset of skills would have an advantage over the average Joe. OTOH having *just* that subset of skills does not make one a math expert in broder terms because those broader skills do not have that kind of substantial overlap with other math skills. It may actually improve the basic math skills of Joe to learn the odds of poker at the level of a top player but it has no other significant overlaps that one would find in the skill sets of a geniune math expert. Anyone can buy a book or go online to read up on the probability needed to play poker. Does everyone who does that qualifies as a math expert? Of course not. Had you understood my line of reasoning you wouldn't feel the ned to ask such absurd questions. Well, maybe to you, No not to me. I know many mathematicians, i.e., real math experts with advanced degrees in math, who are notoriusly poor poker players, because they cannot read opponents, or they show everyone what card they have by the way they bet, or they do not have guts to follow their developed instincts. This would have some relevance if I had said that all math experts by rule are excellent poker players. But i never said or implied any such thing. knowing the odds is probably one of the easiest one to acquire, and, no, it does not take a math expert to do so. I never said it did. please pay attention to the arguments before trying to rebut them. This i will tell you from being related to a top notch poker player, when the pros turn over the cards before they draw you never see a disagreement as to who has the advantage. they always know. You never see both players look happy with their hands. How does that have anything to do with your claim that the math experts are better poker players? Again I suggest you read my claims more carefully. I never said "math experts *are* better poker players." I said "math experts *often* make better poker players" and explained why because knowing the odds of poker, something that comes easy to math experts but does not allways come easy to others is a valuable tool to a skilled poker player. Because all else is not equal. actully on average it is. perhaps you don't know about the mathematical principle of returning to the mean. Wow, everyone, we have the "mathematical principle of returning to the mean" by porkygeorge! You read it here first! Maybe you did. i'm sure others didn't. Of course here are exceptions and momentary abehrations but in the long run the numbers alays return to the mean. IOW *in the long run* all else is equal. It is very easy for a non-mathematician to have a different skill that is even more advantageous in poker, Actually no. You are dead money without this knowledge. A non-mathematician can easily pick up the probaility skills needed to play poker. Well, maybe it is difficult for some of us. If you pick up the knowledge you are no longer without the knowledge. Jeez. Again i challenge you to find one_single_ top poker player that doesn' have a very adept understanding of the odds in poker. Does understanding the odds in poker make one a math expert? Did I say that it does? by definition, I'm a math expert! maybe you defenition. not by anything i have said though. OTOH one can strole down any casino and find most of the amatuers blowing their money at the poker tables don't really know the odds well at all. And there will be a lot of real math experts blowing their money at the poker tables because they don't know how to play poker. Really? A lot? Let's see you support this claim. or for someone to learn the statistics that is important in poker, so that he can outperform a mathematician untrained in poker. Well gee, if someone learns the relevant math to poker then they have the same advantage as the math experts. That's one of the most lame points i have ever seen and i have seen some really lame points. Well, gee, anyone who learns the odds needed to play poker has become a math expert. You might believe that but f you were able to follow my arguments you would see i have never made any such claim. That's one of the most lame points we've seen here. I agree, unfortunately you are the only one saying it. Maybe you should stick with flying elephants. You do not need a degree in math to have a good working knowledge of the probability that is necessary for good poker playing. You don't need a degree in math it simply gives you the knowledge needed, well at least a start. You do need a working knowledge of the odds in poker to play at the top levels. You *need* it. But do you have to be a math expert? No, and I never said you did. How about the many other things you need to play at the top level? Do the math experts have it because they are math experts? No not because they are math experts. Again, at the risk of being redundant I suggest you reread what I have said an try to get it this time. You are arguing against claims that were never made. So the statement "math experts often make poker players" is simply an illogical extension. I am shocked at your failure to see the logic here. Because, frankly, your logic is shocking. How do you know if you keep getting it so wrong in you interpretations? I really don't think you followed it. I said a math expert *often* makes a better poker player. i never said all better poker players are math experts. Is that clear? If not take the following analogy, people who J walk are more likely to be hit and killed by cars than those who don't BUT not all ead people were hit and killed by cars. do you see now? If A then B does NOT mean if B then A. But you seem to be in denial of the value of mathematical knowledge to a poker player. As are the several preceding claims that porkygeorge made. Nope they were just as valid. In a similar way, if all else are equal, then someone who is a musician can be better than others in comparing performances of audio equipment, if the goal is to compare how the equipment is used to reproduce the kind of music he/she is used to hearing. Yep that is the point. But all else is not equal, It is in the long run or do you not understand the statistical principles behind this claim? Do you understand that all else is not equal, OK you didn't understand the claim. To bad. and someone who is familiar with audio will be a better judge in matters related to audio than musicains? Oh really? Now that is ripe. Funny thing is someone can be familir with audio and be stone deaf can't they? Would they be better judges of what we were talking about? The sound of playback compared to the sound of live music? Peronally, I think most musicians will have them beat. Even the rock musicians and the rappers. and it is easy for a good listener, or an audiophile, to develop the necessary discriminating skills to do a better job than the musician who is untrained, in detecting differences in audio reproduction performance. No one is claiming that there are no exceptions to the basic rule that musicians have this inherent advantage. But you seem to claiming that expert listeners, or audiophiles, somehow do not have this inherent advantage. They don't. They have to aquire it. I would trust the expert listener in his ability to discriminate audio equipment much more than I would trust a musician. In most cases a musician is an expert listener. Not in audio reproduction. Please prove that musicians skills do not transfer to the ability to dscriminate between live sound and play back. I think this is utter nonsense. the inheent familiarity that comes with hearing so much live music for th sort of musicians we are talking about and the critical nature of that listening would make for an undeniable body of experience with the reference in question. If you cannot see the obvious advantage in that ast expereince then we really don't have much to discuss and you may as well use unfamiliar recordings of oboes to evaluate playback instead of familiar recordings of pianos. sAfter all your exereince with live piano naturally would not help you. Right? For instance, a lot of musicians are not even aware of the fact that to make a meaningful comparison when differences are subtle, levels much be matched. Irrelevant. The claim is of greater sensitivity and analysis do to experience not of greater abilities to set up comparisons. It's relevant because it means some musicians have trouble making a valid comparison, and their conclusions are often faulty. No, the discussion ws not about the set up it was about the sensitivity and analysis skills. Scott |

Most musicians cringe at a pitch increment of 4% - about half a semi-tone. I have been involved in perception tests and observed their reaction first hand. Iain Half of a semi-tone would make ANYONE who doesn't have serious hearing damage cringe. In a pitch shifting experiment, we observed that few people, with the exception of the musicians on the panel, reacted to a half-semitone change, implemented in small steps over 32 bars. You would be surprised at the low level of audio perception even among audiophiles Jenn. Iain Implemented in small steps over 32 bars, I would agree. |

Or admit that your *opinion* is about this matter is merely an opinion. Show me a single reference to a scientific experiement that shows what you said is true. *You're* the objectivist. I think of myself as a non-subjectivist. As far as I can tell, perceptual phenomena aren't real to you unless they are supported by reliable, repeatable evidence. So let's have the evidence that sensitivity to sound is comparmentalized. I am very familiar with piano sounds, and can easily tell the differences between different pianos. I am clueless when it comes to telling one oboe from another. Then please answer this question. If you were asked to evaluate the fidelity of a sound system would you be able to do as good a job of evaluating it using an unfamiliar recording of an oboe as you would with a familiar recording of a piano? Why or why not? Totally irrelvant issue. Actually it is entirely relevant and the answer you would likely give would completely undermind your indefensable position. i believe that is why you refused to answer the question. I gave you the reason why I did not answer that in the next paragraph, so you don't have to guess... I didn't buy it though and explained why. The question asked was whether listening ability was compartmentalized. I showed evidence that it is, No you showed evidence that familiarity with live sounds is in fact advantageous when evaluating playback equipment for it's fidelity to live sounds. Then you simply fail to comprehend. No I comprehend. IMO you don't like someone telling you that they my know what live music sounds like better than the average Joe and are better equiped to assess deviations of that when listening to playback than the average Joe. Well, IMO you really don't like it when that person has beliefs about audio and preferences that don't jive with yours. Your arguments actually support the point though when you pointed out that familiarity is key. that is why someone like you would do better evaluating playback equipment using familiar recordings of piano rather than unfamiliar recordings of an oboe. You live with piano sound and you know it well. that clearly is the point you are trying to argue against. Someon like Jenn lives with live music of many textures and knows the sound of it well. Why is this so dificult to accept? Is it because she finds LPs more life like than CDs by and large? I showed that certain musicians may be extremely familiar with some kind of sonic difference, but worse than audiophiles in detecting other differences. "Other differences" What differences are we discussing other than the difference between live music and playback? the arguement that you showed it is compartmentalized simply does not hold water in this discussion because we are talking about one compartement, the sound of live music compared to playback. There are many, many different kinds of live music, so being a musician does not mean that one is familiar with all kinds of live music. No kidding? Perhaps you thought Jenn was arguing that musicians are better at detecting differences betwen live music and playback with unfamiliar instruments or with rap music based on their familiarity with the live acoustic muic that they commonly create and listen to? I don't see anyone arguing that position do you? If so I uggest you review the thread. Did you really not understand that the argument that musicians are more familiar with live music meant that said musicians would be comparing sounds they are familiar with in live music to play back of sounds they are familiar with in live music? I find that alarming. A rap musician may not extremely limited in his experience with live classical music, and much worse than the typical classical music lover in his appreciation of that genre of music. Obvously when we are talking about the inherent advantage a musian has by virtue of their familiarity of live music we are talking about said musicians using music they are familiar with in the playback as well. Are you seriously now saying that Jenn is wrong about her claim to have an inherent advantage in assessing the fidelity of playback equipment because she might only be allowed to listen to rap music for her comparison? Do you not see just how ridiculous your position has become? And the concept of "live music" being important in detecting subtle differences between audio components is questionable. It is very important if one uses their high end audio systems for that purpose. No one is suggesting that rappers do it. we are talking high end audio are we not? You have brought up the term "fidelity" have you not? "Fidelity" to what? I thought it was live acoustic music we were discussing. You want to talk about rap and talk about "fidelity?" The differences imparted on the "live music" by the performance venue, the recording and mastering engineers' manipulations, etc., are much more than any differences caused by nominally competent electronics (vinyl systems excepted). IYO. Apparently not in the opinion of some people with vast experience in listening to live music and playback of live music. You are entitled to *your* opinion but you are not entitled to agreement from everyone elese with ears and an interest in the supject. I am truly sorry that it troubles you so that someone with such experience disagrees with you on the significance and merits of certain equipment. But that's life. Obviously musicians are more familiar with the sound of live music because they are around it all the time and are paying vey cloase attention to it. since one can have very acute listening ability for some type of sounds, but poor ability in others. You mean like musicians having greater listening ability for the sound of live music but perhaps not the sound of trains, explosions or Foley effects? I would agree with that and would not expect musicians to have any greater ability to assess the sound of movies for home theater. Let's give another example: No lets not. This is about high end audio. Even amoung objectivists and subjectivivsts it is agreed that a discussion of fidelity must involve live acoustic instruments as a reference or at the very least live acoustic sounds of some sort. I have heard that someone likes to use Lunes crowing in the morning or something like that. There is no relevance to discussing anything else especially when the claims made are so obviously specific to the sound of live acoustic music and a musician's inherent advantage in recognizing the fidelity or lack there of in the playback of live acoustic music. do you expect a rap musician to appreciate the subtle differences between different acoustic instruments like oboes, as well as classical music lovers? Do you seriously think that is the position being presented when it comes to a musician's inherent advantage in assessing the fidelity of playback when compared to live music? If so the whole discussion went right over your head. If not then you must know this is purely a burning straw man. you pick. Or do you expect the classical musicians to be better than the rock music lover in differentiating different electric guitar sounds? No. Clearly I don't. How did you fail to see that? But their expereinces tend to be quite relevant to one of the most common uses of high end audio. The play back of recordings of live music. failure to respond to my snipped points noted. What you failed to notice is that you are simply regurgitating the points made by Mike Mossey and Jenn, and it is pointless to start another round of endless discussions with you, as far as I am concerned. No matter how much you want me to do so. But you arleady are. You are free to not respond. Responding to points made by snipping them and claiming they were irelevant is pretty weak IMO. Scott |

You have to take the precaution to match them. There is no calibrated standard level in consumer audio. this is apparent. coming from pro audio, i find this to be a nuisance. So why do you think SACD players have to have 6 dB higher output levels? If you can't answer that, perhaps all that you have learned from playing live music is really not that useful when it comes to understanding audio. don't get me wrong, 6 dB is no magic figure. but i can understand why the output is hotter. there's so much more dynamic range with SACD. if you don't represent some of that resolution as a hotter signal, you're going to lose information in the noise floor. especially on a less than incredible player (referring to the internal audio circuitry here). 120 dB of dynamic range. how many preamps out there have a -120 dB noise floor? so, it looks like manufacturers have chosen to eat a little headroom as a compromise to losing detail. now i'll need a new preamp :-P No you don't. uh, interesting assertion. without even knowing what I'm using, you know that it has 6 dB more headroom to give? fact is, my SACD player is putting out more than 2.5 V RMS on louder parts, and that is reading with a relatively slow-reacting meter. I'm sure a 'scope would reveal 5 V peaks or more. The preamp I have is more or less -10 dBm equipment, and this signal is too hot. my old player measures up around 1.2 V with the same music playing. This is already about +4 dBm, which is hot for consumer gear. in both cases this is measured virtually unloaded, but the preamp's inputs are high-z. -- stealthaxe |

You clearly do not know just how sophisticated instrumentation is. If there is any real difference between the tone you prefer and another tone, it is trivial to measure it. sure I do. first, I said match tone, not measure difference. it's not only about recognizing a difference but also what to CHANGE to nullify that difference (for example increase idle current by 30%). this part is quite a bit more difficult and something your instrumentation will not tell you. there is a company called Line 6 that makes digital models of tube amps. they spent YEARS in order to approximate the sound of certain tube amplifiers. the result is quite nice but still not on the mark. You don't seem to grasp that the human ear is actually a rather imprecise device. isn't that kind of working against the argument that ANYONE can hear differences in equipment? anyway, I'd say that the ear is not imprecise, but inaccurate. Why do you think it would be hard to measure in the 40 Hz region? Why do you think it would be easier at 1 KHz? You really should question these assumptions. at least the equipment I have access to has limits in the digits of resolution past the decimal point. 0.01 Hz is a larger part of an octave at lower frequencies. this is not an assumption, but something i've observed. For electronics like CD players, amplifiers, and speakers, or instrumentation such as a frequency counter, the difference between 5000 and 5001 Hz is huge. and how does this imply that someone can hear this better than a musician? -- stealthaxe |

What musicians are trained to hear are gross compared to the differences between audio equipment, except between speakers or vinyl equipment (in which case, it is really largely preference). ok so i'm going to agree to disagree with you. clearly, without the viewpoint of both sides, you can't see my POV. there endeth my argument. You have to take the precaution to match them. There is no calibrated standard level in consumer audio. this is apparent. coming from pro audio, i find this to be a nuisance. So why do you think SACD players have to have 6 dB higher output levels? If you can't answer that, perhaps all that you have learned from playing live music is really not that useful when it comes to understanding audio. don't get me wrong, 6 dB is no magic figure. but i can understand why the output is hotter. Then you understand wrong. there's so much more dynamic range with SACD. if you don't represent some of that resolution as a hotter signal, you're going to lose information in the noise floor. especially on a less than incredible player (referring to the internal audio circuitry here). 120 dB of dynamic range. how many preamps out there have a -120 dB noise floor? so, it looks like manufacturers have chosen to eat a little headroom as a compromise to losing detail. now i'll need a new preamp :-P No you don't. uh, interesting assertion. without even knowing what I'm using, you know that it has 6 dB more headroom to give? It does not need 6 dB more headroom to play SACDs, because SACD players do not give a 6 dB higher output level. fact is, my SACD player is putting out more than 2.5 V RMS on louder parts, and that is reading with a relatively slow-reacting meter. I'm sure a 'scope would reveal 5 V peaks or more. The preamp I have is more or less -10 dBm equipment, and this signal is too hot. my old player measures up around 1.2 V with the same music playing. This is already about +4 dBm, which is hot for consumer gear. in both cases this is measured virtually unloaded, but the preamp's inputs are high-z. You made a wrong assumption that SACD players have "hotter" outputs. DO yourself a favor and check measurements, like he http://stereophile.com/hirezplayers/...ny/index4.html Another point for you to ponder is where can you find a SACD recording with a dynamic range of 120 dB. Or what the noise floor of your listening room is. |

I ask because I have observed on two universal players now, when digitizing the two-channel analog output, that the 'default' channel level outputs a clipped signal. Clearly on the Sony SACD players, the output level is the same as regular CD players" around 2V. What level did the universal player's outputs clip at? I suspect that the universal player's levels are adjustable (e.g. for channel matching in surround sound applications), and the gains can be set too high to the point of clipping. In which case, nothing in the preamp can help, regardless of how good is the preamp's headroom. To fix it I have to lower the player's output levels in the channel level menu. However, I'm not sure this is confined to SACD; I'm still investigating. Would love to hear more about it. Which players are these, and what discs show the problem? I have a Pioneer player, and the levels seem the same as other CD players. |

Answer (and please correct me if I'm wrong): Poor tone quality, faulty attack and release, noise (i.e. sounds that aren't part of the music), faulty room resonance, distorted imaging. I think you're wrong, in the sense that we don't really know much about *how* particular distortions are perceived by listeners--or, for that matter, whether most listeners perceive it the same way. But this isn't something we really need to know. Strange. You are not interested in investigating how people experience distortion in musical terms, and yet you are absolutely sure that some distortion in analog is what is responsible for triggering live music pattern-recognition neural machinery. This in spite of the fact that every proposed distortion mechanism would *change* the patterns that musicians have carefully established in the music. I listen to the gear using a known recording and compare the sound I am hearing with the actual sound of instruments being played; a sound with which I'm very, very familiar. Yes, you've said. And you think you're very good at making this judgment. But all the evidence I've seen suggests that, to the extent that this is a testable skill rather than mere circular reasoning, you aren't every good at it at all. How do you propose to test the skill? Mike |

You may be better off going through a preamp first and use the preamp's volume control to attenuate the level that goes into the 2496. |

On the Pioneer DV-45a universal player, the user has the option of using 'fixed' or 'variable' channel levels. The 'variable' slider has a -/+ 6dB range. The 'fixed' level is equivalent to setting the 'variable' level to its maximum (+6dB). Output of typical music tracks using the 'fixed' setting usually overloaded the input of my soundcard (M-audio 2496 , which has a nonadjustable peak analog input signal level of +2 dBV) when the player analog out was connected directly to the soundcard. 'Variable' in its middle setting (0 dB trim or boost) did not. This behavior was not specific to SACDs; it applied to all sources. My current player, the Yamaha S2500, has a separate set of adjustable channel level for SACD sources. The default ("0") setting clips the 2496 (as does the 'SACD Direct' setting, which bypasses the channel level adjustments). Adjusting the SACD output level downward in the player keeps it from clipping at the soundcard. -- -S "The most appealing intuitive argument for atheism is the mindblowing stupidity of religious fundamentalists." -- Ginger Yellow |
