For those of you out there that do believe that the cable makes a difference... Wouldn't it be pretty easy to test the sonic difference by making a test audio file with different frequencies, and then setting up a mic by one of the drivers to record the audio played through each cable? Although it wouldnt be 100% scientific, I would assume that done a bunch of times, we should be able to see a difference of the waveforms of the recording.
And, for another test to check data loss.... If you were to compare the time it took to transfer a very large file several times from one drive to another using two different cables, if the cables really do make a difference, there should be consistency with the copy time of the expensive cable, and the cheap cable should have a large variance from one copy to the next. I think between those two tests, which can be done at home with a little preparation, we should have a good idea on whether or not they make a difference.
The biggest question for those that love the expensive cables, what would your response be if there was true scientific proof (beyond some minor home-based tests) that the cables truly did nothing, and the effect was psycho-somatic? And for the non-believers, what would your response be if there was true scientific proof of sonic changes?
I would think that if there was a measurable (aka real) benefit, companies would eat it up and advertise the hell out of it. I went to the product pages of all the USB cables mentioned in this thread (and a few others), and not a single one mentioned anything about sonic differences, only that the cable is the best ever and will provide the best listening experience. I could not find a single objective statement on how the listening experience would change. Outside of the audio world, these kind of sales are typically called scams.
That's interesting..... 2 extra paragraphs appeared that weren't there when I quoted your post.....
Another way to approach this might be to investigate what uelover is reporting, rather than discounting it. Certainly he is hearing something and has developed preferences for certain cables. He says "more resolving" I'm still not sure exactly what he's hearing.
About making recordings. Prog Rock Man posted about a tool called the Audio DiffMaker. Is this what you're referring to? You make a recording with one cable, change cables and make a second recording. The program will null out everything that is the same and you are left with only the difference between the two cables.
