I remain skeptical... I'm sure I wouldn't hear a difference. (But, I might guess 7 of 10 correctly!)It's "interesting" that none of the participants did better than 8 of 10, or worse than 7 of ten.
Without more information, we're left to speculation, which to me makes these these types of discussions are a complete waste of time.I respectfully suggest people refrain starting such threads when there is such a blatant lack of pertinent information in the future.Please take my comments from the point of view of a regular member and not a moderator. AFAIC, there is nothing in violation of the TOS regarding the content of this discussion, though it is questionable that it rises to a level deserving placement in the listening tests sub-forum; hearkening back to my original concern.
To get to the point, the result was as follows: Participant 1 was able to correctly identify X 7 out of 10 timesParticipant 2 was able to correctly identify X 8 out of 10 timesParticipant 3 was able to correctly identify X 7 out of 10 timesI'm no expert in either statistics or mathematics (and I'm also a cable sceptic), and as far as I understand none of these results are statistically significant. But that all three tests should have a relatively high number of correct answers is interesting, and if we add the results together (I don't know if that is statistically correct), you would get 22 out of 30 correct, hvis IS statistically significant.
That doesn't seem very rigorous at all, nor very well thought out.
The "noname" cable was a 4mm^2 cable from a Norwegian company "Biltema" (www.biltema.no) that sells more or less everything.
The term "reliably distinguish" is a bit vague. Do you mean with 100% accuracy?

Do you mean with 100% accuracy?Although the overall result was statistically significant none of the individual listeners could achieve a statistically significant result. This is at odds with the advertising blurb, e.g.“ The high tolerance conductor spacing used in this cable means that musical performance reaches new heights. For detail, resolution and transparency Baldur will surprise and delight you. “One would have hoped that a cable that surprises and delights would have been more detectable.Suggestions for improvements would be for more than ten tests to see if individual listeners could achieve a statistically significant score and for listeners to attempt to describe the difference. For example, was cable X more delightful or was it a bit louder.
