Do all amplifiers sound the same?
"Steve" wrote in message
... What was your recent "audition"? These things have to be done carefully, with the exact same system (I assume it was) but also well volume matched (use a test tone and multimeter to check the voltage output from the amp.) This was at a dealers and I had no way to objectively set the volume to equal. So I set the volume by ear changed the volume each time up or down according to whim. Not very scientific but similar to what one would do at home. Unless you use a voltmeter at home :-) Available at Radio Shack, cheap. |

Some of you guys talk as if double-blind ABX tests are so easy to set-up and perform that one would think that you hold such tests regularly. They are not easy to set-up or perform and they require considerably more than one person to perform them. They simply aren't practicable in most situations. |

Any test instrument, including one's ears, has limitations. Their proper use includes knowledge of and proper consideration of their shortcomings. Unfortunately, the vast majority of people seriously over-trust their test instruments (meters and ears equally) and thus are more than eager to be led to appropriately erroneous conclusions as a result. They do require a bit of training, however. And many people who say that assume that training allows them to ignore the fundamental limitations of the instrument, indeed, even "entitles" them to ignore them. No matter how much they are trained, one's ears has pretty serious limitations. That they are backed by very sophisticated brains is both a bug AND a feature. Those brains allow one to supplant things the ears themselves are incapable of. |

om: Some time ago the now defunct stereo review had an interesting article on blind a/b tests between different amplifiers - I saw a reprint here; http://bruce.coppola.name/audio/Amp_Sound.pdf After a hiatus of many years I am now putting together a system and every one I talk to tells me there is a difference between amplifier sounds. I am sceptical and in a recent audition could not tell a Creek EVO from a NAD 325 BEE (through EPOS M12.2 speakers with a Creek cd source). Has any more work been done on this subject, esp. blind a/b tests? Steve This is discussed regularly within the pages of Audio EXpress. (www.audioeXpress.com) ..I will be glad to send you a copy of the pertinent articles if you want...(I suggest subscribing...it is the only audio- centric magazine that I read for facts instead of fiction) just shoot me an email if you want the articles. =Tynan |

THe point is, the claim you make -- for 320 kbps mp3 no less, which when done *properly*, is very difficult to tell from source, for untrained listeners -- is extraordinary, thus the evidence for it should be sound. Yours isn't. Some of you guys talk as if double-blind ABX tests are so easy to set-up and perform that one would think that you hold such tests regularly. They are not easy to set-up or perform and they require considerably more than one person to perform them. They simply aren't practicable in most situations. Utterly wrong in this case. An mp3 vs source ABX is perhaps the most simple to set up, as software 'ABX boxes' have already been developed, and are free. MP3 codecs --LAME in particular, considered the best -- have been developed using ABX tests to tweak them at every step. ___ -S "As human beings, we understand the world through simile, analogy, metaphor, narrative and, sometimes, claymation." - B.

For loudspeakers, I would look at the specs, check any measurement-based reviews and finally, listen in my own room to check that the particular inaccuracies of the loudspeakers are something I can live with. Measurements come after I've bought it to make sure the manufacturer's specification is being met. S -- http://audiopages.googlepages.com |

In fact I rarely audition gear; I would only seriously desire or feel the need to do so, for loudspeakers, but that's rarely feasible to do at home (and listening 'in store' is not a good substitute). And any such auditions are prone to sighted bias effect. Solid state amps, preamps, CD/hard media players, cables are commodity gear, more likely to sound alike than not in a fair (blind) test when operated withing their limits. (I don't deal with turntables or tube gear, gear that introduces irreversible , supposedly 'euphonic', distortion). So I keep up on gear evolution, decide what features I want, then I choose gear that has them, based on manufacturer's information, and reviews, and published bench tests. Appearance and price can also be factors in my final choice. I mostly buy online, I don't often visit 'audio salons' except to sightsee. At all times I'm aware that 'sighted' reviews and reports on sound are suspect, including my own. I put as much or more effort into speaker placement and room treatment. It stands to both reason and practice that choice of loudspeaker, and attention to room conditions, makes *BY FAR* the most difference in sound quality. It really is just that simple, once you jettison all the nonsense promulgated by audiophile culture. ___ -S "As human beings, we understand the world through simile, analogy, metaphor, narrative and, sometimes, claymation." - B.

"Arny Krueger" wrote in message ... Some will argue that well-made amps that measure the same will sound the same. The myth here is that two amps could measure the same. Even each channel of a stereo amplifier will measure differently, given sufficiently accurate measuring gear. I don't believe the measuring tests are really that accurate. That's too bad. If you doubt this, consider: voice recognition is extremely difficult for even the most sophsticated equipment, yet trivially easy for even children. Even in the past few days I have transacted very exacting business with computers, based entirely on voice recognition. The same is true for image recognition. I have likewise completed several transactions based on image recognition. Measurements might be good enough for the cell phone generation, but that ain't sayin' much. Am I missing something here, or do we have a case of attempted proof by means of falsified assertions? Theoretically, if it can't be measured it can't be heard. Practically speaking, appropriate measurements readily resolve differences that have never been heard. For example, there are no known instances of humans reliably perceiving 0.01 dB level differences even at the frequencies where the ear is most sensitive, but 0.01 dB level differences are very easy to measure with a great deal of reliability and certainty. But just because it can be measured doesn't mean it is being measured. Irrelevant to the issues I raised. It is completely illogical to attempt to falsifiy a claim about measruements that have been made on the grounds that they might not have been made. |

And since even if everything we hear could be preceisly quantified and weighted according to the requirements of human perception, that still doesn't mean that the ordinary audiophile would have access to the equipment with which to make those measurements for himself. There's nom chance that the "average audiophile" would have the knowlege or motivation to make any reasonable set of audio measurements, or be able to interpret them properly. After all, the various high end ragazines and web sites have been making sport of audio measurements for more than 30 years. Their motivation for attacking audio measurements is very clear - they have created a new economy for audio evaluations where reviewers can simply claim as the whole truth, whatever flies into their heads for whatever reason. If a reviewer bases his claims on some measurement or other reliable repeatable procedure, then interested parties could try to duplicate their claimed results. By avoiding making claims that are justified by anything but unsupported opinons, the reviewer can not be held accountable. We have two instruments we can use when choosing audio equipment and we carry them with us everywhere we go. Use 'em! The fallacy here is the idea that any audiophile's unassisted ear is always a realiable tool for discerning the performance of all kinds of audio products. |

It's often *quite likely* that your judgement of sound quality is not fairly based, in such 'auditions'. The comparatively few cases where one can safely assume there's real audible difference, include comparisons where electromechanical transducers are involved (loudspeakers, tt/cart). Even there, of course, assessment of *sound quality* can be polluted by non-audio factors -- this is an elementary fact of human psychology -- which is why the CRC and Harman employ a blind comparator setup for loudspeaker evaluation and development. But, some people buy a new car without driving it first, others buy clothes without trying them on. There's simply no accounting for preference, which is all that you are stating. This is a false analogy. There's little a priori reason, from the technology and physiology involved, to assume that different models of car WON'T 'drive' different in some way, and much to assume the opposite. Contrast this to audible difference between amps, preamps, CD players, cables. To make such an analogy you;'d have to completely ignore the idea that perception of difference involves physiological thresholds; you'd have to assume that the thresholds involved in *hearing* the measurable differences in audio gear, are at all comparable to those involved in sensing a difference in 'driving' (which btw you haven't defined; in what sense, exactly is 'driving' analogous to 'hearing'?) Similarly, you need to define what the claim is you're making about clothes choice. In what sense are 'different' clothes perceptibly different? IS a difference in fabric , in cut, in color, between , say, two shirts, AT ALL comparable to the measurable difference between CD players? What I *am* stating, which audiophiles like you tend to gloss over, is that *preference for sound* is not necessarily the result of the qualities of the *sound*. And thus it's often self-delusional to be CERTAIN about it based on sighted comparisons. ___ -S "As human beings, we understand the world through simile, analogy, metaphor, narrative and, sometimes, claymation." - B.

Electronics of modern competent design do not sound different so why listen? Regarding clothes, do you try on underwear, shirts, knitwear before buying? Suits need to be fitted to the person so should either be made to measure and fitted, or if bought ready-made then at least tried, and other items like overcoats may need to be tried for comfort, but there's no analogy that I can see between audio equipment and clothes. Cars, like outer garments, will need checking for comfort and fit, i.e. do the seats adjust comfortably, is the visibility suitable etc, so a test-drive is appropriate, but again, what is the analogy between cars and audio equipment? A better analogy perhaps is wine, as the suitability of wine is entirely subjective. One might buy a bottle without tasting, but would you buy a crate? However, the analogy with wine only applies to those components, like loudspeakers, that *do* have a subjective component to their suitability, it fails in the case of electronics that, excluding a few outre components like SET amplifiers, don't have a subjective component to their suitablity.

One important lesson of our early days with ABX (now 30 years ago) was that when auditioning modern non-acoustical gear, as most audiophiles and reviewers do, biased or random results are *certain*. I put as much or more effort into speaker placement and room treatment. It stands to both reason and practice that choice of loudspeaker, and attention to room conditions, makes *BY FAR* the most difference in sound quality. Agreed. It really is just that simple, once you jettison all the nonsense promulgated by audiophile culture. Both recordists and live sound professionals tend to use the word audiophile as a perjorative. Synonym with clueless and opinionated. You don't cite an example, so I don't know what "nonsense" you're talking about. It is true that there is so much nonsense that is widely accepted as revealed truth, that one might not know where to start. Here's a good starting point: http://www.theaudiocritic.com/downloads/article_1.pdf It's certainly nonsensical to buy audio equipment without listening. That might be a good candidate for the 11th lie. Choosing gear that can logically be expected to sound alike, based on a listening test is certainly nonsensical. The belief in universal audible differences among pieces of good audio gear is nonsensical. But, some people buy a new car without driving it first, Been there, done that and just about a year ago. Specifically, I bought a Mercury Milan based only on a driving experience with a Ford Fusion. Furthermore, the two cars differed in terms of a number of signficiant pieces of optional equipment. The basis for doing this is called by some "abstract reasoning". I recommend it when possible. others buy clothes without trying them on. Hence the hi8storic popularity of clothing retailers such Lands End. There's simply no accounting for preference, which is all that you are stating. There is no rational reason to prefer one audio component over another based on sound quality when they cannot be distingushed based on sound quality. |

writes: Actually, it's not guesswork at all. The series resistance the voice coil dominates, and unless the other series resistances are pathologically large and the so-called damping factor is larger than 10-20, the amplifier's output resistance will have NO appreciable effect on the damping of the system. You're speaking in static, DC terms. Agreed, that the statement was couched in static terms, but it applies equally well to the dynamic properties of a loudspeaker. What about dynamically? Because the loudspeaker is a dynamic system, its AC properties differ from its DC properties. However, the dynamic properties of a loudspeaker enhance Mr. Pierce's argument. Because a loudspeaker is a passive system, its AC impedance is *always* higher than its DC impedance. Simple math shows that increasing the impedance of a load minimizes the effects of the impedance of the source. Therefore, the effects of the amplifier's output impedance are less in the audio band than they are at DC. For example, when the voice-coil is traveling and the back-emf is opposing the amplifier's output voltage? The back-EMF increases the impedance of the loudspeaker. Therefore, in some sense it decreases the importance of the source impdedance of the amplifier. In practice, it is the variation between the ranges where the speaker's impedance is high and low that makes us prefer power amplifiers that provide a low source impedance. Yes, there is still the DC resistance of the coil in series, but the amplifier is working harder than under DC conditions. Actual laboratory observations show otherwise. If you observe an amplifier *working*, you can externally determine that it is drawing power and making heat. In some cases the output devices and some internal inductors may even *sing* a little. These effects are almost always maximized when driving a resistive load that is equal or approximate to the DC resistance of the speaker. A counter-example would be a capacitor with low ESR, but in practice these are rarely hung across the output terminals of a loudspeaker without some series resistor in place. When you hook up the speaker, these effects are usually appreciably lessened. Similar effects can be observed when you monitor voltages and currents inside the amplifier's circuitry. Therefore, a resistive load whose resistance is the same or approximates the DC resistance of a loudspeaker is generally, across the audio band, a tougher load for an amplifier to drive than the speaker itself. I say almost always only because there are a few loudspeakers that present a high impedance to DC. Such speakers usually have built-in series capacitors that can act to enhance low frequency performance in some cases. Very few people have operated power amplifiers under maximum output conditions into a loudspeaker, and not been in the acoustical field of the loudspeakers. The acoustical field of the loudspeaker operated under these conditions tends to distract most people. |

I used to believe that objective measurements alone were all that one needed, and I still believe that objective measurements can tell us most of what we need to know about a system or component. Well, try looking objectively at a chess board at the beginning of a game and determine who will win - black or white. This is relevant how? For one thing, the two sides of a chess board are stipulated to give equal chances to the competitors. They are designed to be functionally identical when it comes to predicting the outcome of the game. In contrast the two pieces of equipment are different from each othe, they are different designs. For another thing, the outcome of a chess game is dependent on the players, not the board. This example would die a certain death if presented in a 101-level middle school class about rhetoric! Objective computers measurements can't figure out that one either. Actually, they can especially when the differences are sufficiently large to matter. Here again we have an attempt at proof by means of a pair of ludcrous assertions. There is a lot in this world that isn't known or understood, trust me. True, but relevant how? |

Some amplifiers sound different, some don't, depending on what they are connected to. Actually, all amplifiers sound different as typically evaluated by audiophiles and high end reviewers. The differneces are a consequnece of the absence of experimental controls that have been repeatedly and reliably shown to make big differences. Don't get hung up about others opinions and blind tests, there is no definitive answer. Actually, there are many definitive answers. One of them is that listening tests in audio salons are designed to make amplifiers sound different. Select a few well regarded units to audition and make up your own mind. With those speakers, the differences between amps will be subtle compared to a speaker upgrade. Agreed that speakers have a strong tendency to sound different. But among speakers of a given quality level, the differences due to the differences in the acoustics of various listening rooms are even stronger. Reasonably good speakers of a kind, for example competitive bookshelf speakers, sound more like the rooms they are listened to in, than they have a characteristic sound of their own. |

The point here is that I don't care that others say it's my imagination. I know it isn't. This statement can be distinguished from a statement of religious faith how? I maintain that anybody who says that MP3 is as good as the uncompressed original simply can't hear. Given the lack of reliable evidence to back this up, and the goodly volumes of reliable information that denies it... Some of you guys talk as if double-blind ABX tests are so easy to set-up and perform that one would think that you hold such tests regularly. ABX tests of lossy-compression products and their parameters are among the easiest listening tests there are to set up and perform. I daresay that anybody who can't set one up and run it well has indicted their abilities to use a computer effectively. It's a three step process, easy as 1-2-3 (1) Compress .WAV file by whatever means you wish to evaluate (2) Uncompress lossy-compressed file back into a .wav file. (3) Compare pre-compression .wav file with post-compression .wav file using readily-avilable DBT test software. They are not easy to set-up or perform and they require considerably more than one person to perform them. What's easier than 1-2-3? They simply aren't practicable in most situations. Agreed - and their lack of predictability is part of their charm. Why do a test if the outcome is so easily predicted by you? |

It's a preference. You're entitled to your preference. That we don't agree doesn't make me "self-delusional," no matter how noisy your objection.

audio culture nonsense?

Steve responds: ...'nonsense' would include neary every 'review' ever published in the audio press, or on the interwebs, regarding the 'sound' of different audio cables. Add to that the numerous reviews claiming striking , even soul-changing differences between amplifiers and disc players. "Soul-changing" differences????? Would you prefer 'danceable' cables? Examples, please! And - what is the "interweb?" It's a joke. Not to mention the 'effects' of risible 'tweaks' such as the 'LP demagnetizer' touted by your fellow vinylphile Michael Fremer, Mr. Fremer is not a "fellow vinylphile" of mine and we are not associated in any way. Neither am I familiar with the 'LP demagnetizer,' so I don't know what you are talking about. ...or the 'Intelligent Chip' that has so excited certain excitable parties on Audio Asylum. Again, I'm not familar with the 'Intelligent Chip,' so I don't know what you're talking about. So, it's *your* ignorance of audiophile claims, not mine, that we're dealing with here? Or, hell, just page through the gear catalogs of Elusive Disc or Music Direct I've never seen the Elusive Disc catalog. If there's something in Music Direct that you find offensive, please provide a specific example.

There's only a point in listening to electromechanical transducers that "can" sound different, and then, in the case of loudspeakers, only in one's own listening room. Electronics of modern competent design do not sound different so why listen? A point of view not supportable. I say that electronics of modern, competent design DO sound different. The only question is do those differences mean anything to you, personally? If not, fine, but to many they mean a great deal, your scoffing notwithstanding. Regarding clothes, do you try on underwear, shirts, knitwear before buying? Suits need to be fitted to the person so should either be made to measure and fitted, or if bought ready-made then at least tried, and other items like overcoats may need to be tried for comfort, but there's no analogy that I can see between audio equipment and clothes. Cars, like outer garments, will need checking for comfort and fit, i.e. do the seats adjust comfortably, is the visibility suitable etc, so a test-drive is appropriate, but again, what is the analogy between cars and audio equipment? A better analogy perhaps is wine, as the suitability of wine is entirely subjective. One might buy a bottle without tasting, but would you buy a crate? However, the analogy with wine only applies to those components, like loudspeakers, that *do* have a subjective component to their suitability, it fails in the case of electronics that, excluding a few outre components like SET amplifiers, don't have a subjective component to their suitablity. Perhaps you just can't hear that "subjective component". |

It's a pity to forsake listening entirely simply because a dubious result is possible. One important lesson of our early days with ABX (now 30 years ago) was that when auditioning modern non-acoustical gear, as most audiophiles and reviewers do, biased or random results are *certain*. I put as much or more effort into speaker placement and room treatment. It stands to both reason and practice that choice of loudspeaker, and attention to room conditions, makes *BY FAR* the most difference in sound quality. Agreed. It really is just that simple, once you jettison all the nonsense promulgated by audiophile culture. Both recordists and live sound professionals tend to use the word audiophile as a perjorative. Synonym with clueless and opinionated. You don't cite an example, so I don't know what "nonsense" you're talking about. It is true that there is so much nonsense that is widely accepted as revealed truth, that one might not know where to start. Here's a good starting point: http://www.theaudiocritic.com/downloads/article_1.pdf Thanks for the reference. I agree with virtually EVERYTHING Peter says in that article. The exceptions? Tubes vs transistors. I think tube amps sound more like live music than solid-state. Digital vs Analog. We've been through this before. The best recorded sound I've ever heard comes from vinyl, not CD. No sense to rehash the argument here. Nothing will be served by it. I also don't believe that double-blind or ABX testing is of much use in comparing electronics. Certainly not in the way its usually done. One of my projects this year is to build myself an ABX switching box and try to correlate the results of long-term listening tests (like I do now) with ABX testing where I have no pressures or boundaries inflicted upon me by outside sources such as time constraints, peer pressure, unfamiliar ancillary equipment (like speakers) and sources, etc. I really want to know. Other than that he is spot-on. I've always maintained that anyone with the interest can develop themselves a pair of "golden-ears" as it's merely an educated way of listening. I also agree that cable peddlers are just one step up from child molesters, or would be except for the phrase Caveat Emptor. Adults buy this stuff and nobody holds a gun to their heads. While (as the article says) it is important to choose quality connectors and conductors and insulation, NONE of these have the slightest effect on the "sound", only upon reliability and the integrity (perhaps) of the connection. Physics ensures that, not any manufacturer's guarantee. Essentially, any $30 pair of Monster interconnects provide the quality of quasi-balanced cables needed to assure a good, trouble-free connection with minimum interference from other sources. One needn't spend more than that (unless one wants to, that is). But Mr. Aczel did not say that all electronics sound alike. Anywhere. It's certainly nonsensical to buy audio equipment without listening. That might be a good candidate for the 11th lie. Choosing gear that can logically be expected to sound alike, based on a listening test is certainly nonsensical. The belief in universal audible differences among pieces of good audio gear is nonsensical. Sorry, but if one doesn't accept your premise (...gear that can logically be expected to sound alike...) then one can hardly be expected to accept your conclusion (that your expectations are self fulfilling). But, some people buy a new car without driving it first, Been there, done that and just about a year ago. Specifically, I bought a Mercury Milan based only on a driving experience with a Ford Fusion. Furthermore, the two cars differed in terms of a number of signficiant pieces of optional equipment. The basis for doing this is called by some "abstract reasoning". I recommend it when possible. Again, there is more to buying a car than that. The Ford and the Milan are based on the same platform, are they not? They share the same suspension, same brakes, etc, In such a case, there is no appreciable difference between those two cars. It is easy to extrapolate the handling and performance of one by driving the other when they are essentially the same vehicle. On the other hand, if one likes certain handling characteristcs, the only way to find a car that has those is to drive them. Suppose, I'm looking for a car that is initially neutral, has quick turn-in with plenty of steering feedback trough the steering wheel, and which can be induced to slight oversteer with application of the throttle. Suppose further, that I'm looking for braking performance that doesn't fade under repeated hard brakingbut can be made to induce understeer or oversteer by judicious application under dynamic driving situations. Are you going to say that these characteristics can be gleaned without driving the cars? others buy clothes without trying them on. Hence the hi8storic popularity of clothing retailers such Lands End. There's simply no accounting for preference, which is all that you are stating. There is no rational reason to prefer one audio component over another based on sound quality when they cannot be distingushed based on sound quality. Again, your conclusions are based on accepting your premise. Those who do not accept your premise are simply not going to agree with you on this point. |

"Harry Lavo" wrote in message
Except that Steven is very quick to accuse anybody who claims to hear what they think is better sounding electronic gear of fooling themselves. That is an assertion of his that generally will pass a carefully done real-world test. It is a very hypocritical position to take, it seems to me, for someone who doesn't even bother to listen, One does not need to bother to listen - we listen to various alternatives as a matter of simply living in the modern world. yet claims to know that others can't hear what he doesn't even bother to listen to or for. It's simple. Every time I or just about anybody else subject exceptional claims about electronic audio gear to careful (non-casual) examination, they evaporate. At this point, thosands or tens of thousands of people have experienced this for themselves. Hence cultural icons such as the ASA, MPEG, AES, SMWTMS, Hydrogen Audio Forum, etc. My evaluation methodolgy clearly indicated many years ago that SACD and DVD-A so-called high resolution formats should fail in the marketplace because they offered nothing that was reliably audible. At this point the general wisdom is that they failed. QED. |

What aspect of modern design allows for a sound quality difference? Is the difference between distortion figures sufficient to cause a sound quality difference? Is the difference in frequency response sufficient to cause a sound quality difference? Is the difference in residual noise sufficient to cause a sound quality difference? I suggest not, as the differences in all these is well below the threshold of hearing for modern well designed equipment. If it's not any of those, then what can it be? If there's a difference, then it has to be quantifiable, otherwise it's down to imagination. S. -- http://audiopages.googlepages.com |

If you mean that F/R/C is Front/Rear/Center, i screwed up (and did it a 2nd time below!) i meant the 3 front speakers: L/R/C In that case, yes the front speakers are the most important, but surround seems to work better when the rear speakers are at least RELATED to the front ones - like being smaller versions of the same make that share a similar sound signature. they're all cone speakers, and yes they're very well "related" in that the sound field isn't striking in any way ...if anything my rear speakers (PSB Alpha B1's) are likely the standout, and even though somewhat small (7/9/12" W/D/H, with a rear port), they have adequate bass for "small" *rear* speakers Bass in the rear speakers is not as important as it is in the front because surround signals are often purposely limited in low frequency response. fwiw, i've listened to more than a few movies with some large low frequency rear response 2. of a tube preamp vs. tube amps, my best guess is that tube amps driving the F/R/C speakers is the best payoff for using tubes agreed/disagreed? Yeah. Tube amps are probably more important (to the tube listening experience) than is the preamp, although, I'd try to go with both. does a 5.1 tube AVR even exist? I dunno. I haven't seen one. But one could do it with individual tubed components. anyway my view is it's down to 3 choices for my next improvement: 1) tube amps for the front 3 speakers, 2) room sound treatment, or 3) better front L/R speakers bill and what does it cost? if anything, a SS AVR with 5.1 preamp outputs (which don't all have to be used) is almost surely the high volume choice (meaning lowest cost; meaning that it could be used with it's own SS amp power for rear L/R, together with a stereo tube amp (for front L/R) together with a mono tube amp (for front center) is likely the low cost way of getting back into tubes) |
