The only real problem with ABX is that it would work.

There is no doubt in my mind that the testing methods used to
evaluate HiFi gear are beyond reproach even though they give answers that some people don't like. My Story Early on I worked as an electronics tech and believed that the advancement of audio quality was a purely scientific endevour. Then the subjectivists got in on the act. I remember going to a HiFi shop and seeing the first Naim setup."where are the tone controls?" I asked. I was told they are omitted because they ruin the sound. They had a Linn LP12 setup along side the most expensive Direct Drive TT available at that time both sporting identical arms and cartridges. I thought they sounded the same until the salesman said, "Listen to the chestiness in Tom Jones voice on the Linn." Well I was amazed, Tom was definitely more chesty on the Linn. Hey this was a lot more exciting than charts and numbers. After that I was convinced that science didn't have all the answers but "HiFi Answers" (UK magazine) did. I brought a Linn to drive my home brew transistor amps. Then I rediscovered tubes. Measure worse sound better. Then "cables" came along and I was floored again, they all sounded so different, this was no illusion they definitely sounded different. After awhile I settled on some cables and was shocked a year later when I dragged out some of those cables to find that I couldn't hear any differences. Oh dear my ears must be going. Then I listened to a Sonic Impact, Oh dear again, that little sucker is doing things my trick tube SE amp makes a mess of. Maybe there is something in THD and IM measurements after all. . . For the end user it is all about "audibility" and not whether there are differences or not. Every stereo amp will measure differences between channels. There are no speakers identical to each other. Buy a pair of $5,000 interconnects and there will be a difference between the left and right, the question is "can you hear that?" DBT ABX are all about establishing what is audible and what is not. So far it seems that the Golden Ears are "on average" pretty much deluded. "On average" however does allow the possiblity that some people may have exceptional hearing. Obviously the golden ears on this forum belong in this group and they are the very people that the scientists would love to test. I only wish that I was able to hear cable differences again, back then Randi's one million dollar prize wasn't on offer.

I will rephrase: Did you keep getting sighted listening illusions of cable differences during normal listening sessions AFTER some DBT or ABX test proved that you CANT tell cables apart? |

1. something can only perform poorly - but, as an esl, I might be wrongly.... 2. How can a test perform poorly? It can only be designed poorly, so the test is open to criticism as to methodology, and the results from such a poorly designed test are invalid. It can also be that the methodology might be designed to test the hypothesis, but the analysis of the results is flawed through errors in the statistical approach. 3. The test subjects performed poorly, being unable to discern differences. Which is it? |

Of those I've seen #2.

So, what is the proper methodology?
None, and I repeat none, of the tests that have so far been conducted, following stringent scientific methodology or not, even hinted at the possibility of audibility of cables of different construction. The general claim was and is - and I charge anybody who now comes forward and softens the claims to: "slight differences" as guilty of subterfuge, evasion and/or outright lying - that the differences are CLEARLY and UNEQUIVOCALLY audible no ifs, whens or buts. If the influences are of a nature as stated, then even a scientifically non rigorous conducted A/B blinded test should reveal such CLEARLY and UNEQUIVOCALLY differences. But none has, not a single one, starting with Tom Nousaines test, tests by members of hydrogene audio, several test on german audio forums, etc. etc. has been able to reveal such audibility. |
