Can We Hear Differences Between AC Power Cords?
我们能听出来不同电源线的区别么？

An ABX Blind Test
一个ABX盲测

我来翻译下结论的第一段吧

Conclusions
结论

To many in the engineering community, blind ABX is an accepted experimental design. Using the blind ABX protocol, we failed to hear any differences between an assortment of generic power cords and Nordost Valhalla. Therefore, we cannot conclude that different power cords produce a difference using the blind ABX protocol. However, we also cannot conclude that there are no differences. We simply failed to prove that differences can be detected to a statistically significant degree using a blind ABX protocol.

很多工程师认为，ABX盲测是值得信服的科学测试方案。使用ABX盲测协议，我们无法在普通电源线和Nordost Valhalla电源线之间听出任何区别。因此，在ABX盲听中我们不能证明不同的电源线会产生不同的效果。但无论如何，也不能证明的确就没有不同。我们仅仅是无法通过ABX盲听测试在统计学上证明不同电源线的不同效果。
