A Blind Test of Cables
I was browsing through Barnes & Noble today and came across a
publication from the UK. I believe it was called Hi-Fi+. They ran what they described as a blind test of cables. I'm not sure if they used an A/B or A/B/A format as I didn't have time to go through the article in depth. FWIW, of the cables in the test, Nordost Valhalla's came out on top. |

After reading through the article, I found that although they claimed it to be a blind test, there was nothing scientific about their process. Not only did they start with the implicit assumption that some cables would sound better than others, they massaged the results in to discard findings they didn't like. Also, there was no control in the test. At no point was a cable tested against itself. Basically, the test was a self fullfilling prophecy fraud to back up their claims that certain cables sound better than others. Not enough testing was done to provide any kind of statistical validity, and because there was no control, the testing process itself recieved no validation. I'm sure those that took part had a fun day out playing with cables that cost more than most people's hifi's, but due to absurd methodology, it was all a complete waste of time. Indeed, no measurements of the cables were taken so that we could see that the resistance, capacitance and inductiance changes between cables would account for any audible differences they perceived.

Wasn't that the same wire that was used against junk wire and no
difference heard in a recent test here? If "on top" means prefered then the nature of the test is suspect, it assumes differences were present at such a high level of audibility as to make such conclusions possible. If two wires are used and the question is which do you like better only a score of 50/50 would show no preference. A 60/40 would show a preference but not illustrate a real difference was being heard. We are programed to tend to hear difference where none exists, as shown when a and b are the same wire and real differences are commonly reported. Thus, if difference was not demonstrated first, audible preference choice is meaningless. I was browsing through Barnes & Noble today and came across a publication from the UK.

All valid points...except for your last sentence. The point of a double-blind listening test is ostensibly to determine *if* there are audible differences between cables, not what might cause them. That sort of research makes for a thorough follow-up, but is not necessary for a legitimate ABX DBT. |
