I don't doubt that on a good quality system, different cables sound subtlely different. Whether that subtle difference is worth 5, 10 or even 20K is another story. However, it just stuns me that there is any dispute over the value of double blind testing to test outlandish claims made for any piece of equipment or cables. Perception is reality. People are programmed to like a 20K cable better than lamp cord, or some exotically expensive preamp over one less so. What is wrong with removing the possibility of bias and just make judgments -- albeit subjective ones -- based solely on what one hears, without knowing the components? It just seems so logical to me that it is weird that there is so much angst about it. Imagine if the FDA decided to permit sales of drugs based on whether someone "thought" that it made them better. Why shouldn't the same apply to audio?
