Remember, by definition, an audiophile is one who will bear any burden, pay any price, to get even a tiny improvement in sound." Only 5% ? Could it be that due to poor component mismatches, the system would have sounded better and higher than just 5% ? The cables, regardless of price, does not produced sound of their own by themselves. I remember back in the mid-90s that I swap and tried at least more than 7 different pairs of cables in order to gain more than just 5% in sonic improvement. I recall some cables costing more made my system sounding less natural. Been there, done that. |

Could it be that due to poor component mismatches, the system would have sounded better and higher than just 5% ? 0% seems about right. That would be about right for someone like Howard ferstler who has a known, and by his own admission, hearing deficiency. When it comes to discerning differences, Ferstler gets 0. You put two and two together and you'll see why he's fuming all the time. snip I recall some cables costing more made my system sounding less natural. Even so, it was proabably 100% imagination. I don't follow your thought because you are abviously keep on guessing as you go. If you're not guessing, can you form realistic idea exposing that the percieved differences I heard while swapping cables did not physically exist ? |

Well Borg, this post is more evidence that ignorance of basic statistics is a common problem among golden ears. It's not a well-formed question. It's not the percentage of correct answers that defines statistical signicance, its both the percentage of correct answers and the total number of trials. And, that's all based on the idea that basic experiment was well-designed. The most fundamental question is whether the experiment was well-designed. Somehow, this showdown at the CES looked like a DBT sans blackbox. Nope. This comment is even more evidence that ignorance of basic experimental design is a common problem among golden ears. The basic rule of double blind testing is that no clue other than the independent variable is available to the listener. In this alleged test, the person who controlled the cables interacted with the listeners. In a proper DBT, nobody or anything that could possibly reveal the indentity of the object chosen for comparison is acessible in any way to the listener. |

I have no idea. I didn't design the test, not did I look at the playback system. I was a listening subject. If you read the article in the WSJ, you will see that Lee Gomes did other comparisons, not just cables. But the only test I took part in involved cables.. John Atkinson Editor, Stereophile |

That was another potential flaw in the tests. I see no controls that ensured that the listeners heard the indentically same selections of music. Therefore, the listeners may have heard differences that did physically exist - unfortunately they were due to random choices by the experimenter, not audible differences that were inherent in the cables. |

Certainty is not in the realm of statistical analysis. Let's say you want to claim the a certain coin is biased to produce heads when flipped. That you flip it 39 times and get 24 heads is not sufficient to support the claim at a 95% confidence level. If you lower your standard or do a lot more flips and still get 61%, the conclusion will change I'm sure there are audible differences. The issue is whether they are enough to make consisten determinations. A bigger issue for those of use who just listen to music is whether the diffeneces are detectable when you are emotionally involved in the music and not just playing "golden ears". |

I doubt that the 39 people who did the test comprised a simple random sample, another design flaw. On the other hand I'd like to see a well designed test using a simple random sample from the population of true believers just to see if they can really. Even if some people can tell, I suspect that it's a very small number. I do know a couple of people who can really lock onto particular characteristics and use then to identify what's playing.

So he is saying that there were actually two separate systems - two source components, two amplifiers, etc. But were there two different sets of speakers too? One would hope not! Using a single set of speakers, there would need to be a switching arrangement to switch the speakers between the outputs of the two different amplifiers through the two different speaker cables. But if there were a properly designed switching network, there would be no need for two different systems at all. There could just be a transfer switch using the highest quality relays to switch between the two speaker cables. That is, a two-throw at the amplifier end and a two-throw at the speaker end of each speaker cable. This would hold everything else constant. If there were really two different sets of speakers, then the experiment was so poorly designed it isn't even worth discussing. Just the speaker position difference alone would likely cause differences in the sound that would be measureably far greater than any cable could cause. Then it also says: "Using two identical CD players, I tested a $2,000, eight-foot pair of Sigma Retro Gold cables from Monster Cable, which are as thick as your thumb, against 14-gauge, hardware-store speaker cable." Two identical CD players and what else? This guy is being very vague. I guess he is just addressing the typical WSJ reader who isn't familiar with or does not care about this stuff. There just isn't enough info provided to evaluate whether the test setup is valid or not. |

It was single blind when it could have been double blind with very little additional expense in terms of time or money. Single blind tests don't control as many important relevant variables as double blind tests - the test was too simple and shoddily done to be worth much analysis. |

This particualr test was badly enough designed to be flawed from the start, never mind what the data actually conclude. |
