Both will have been subjected to the same testing prior to getting approval for public sale, and assuming both worked, different results are impossible. The test was flawed, and simply yet another attempt at causing confusion designed to sell expensive cables.There was a test conducted in HFC using a cheap USB cable and a branded USB cable to scan a photo. The result was that although the image looked the same to the naked eye, the branded USB cable resulted in a file size bigger than the cheap USB cable.

But it's not my belief-set / ideology, it's the truth, it's a fact, and it's realityOnce again you dismiss evidence if it doesn't correspond to your own belief-set / ideology. You have just failed the pfm scientific module!
Tony, am I allowed to elaborate on the details of the complaint I made to the PCC re What HiFi's HDMI cable reviews?
I would say that it is possible for the scanner to give a different file size. This could happen either if the scanner is usb powered and has inadequate supply regulation, causing image "noise" or if the scanner is one of these dumb types where the raw scan data is transferred to the PC without any error detection.Both will have been subjected to the same testing prior to getting approval for public sale, and assuming both worked, different results are impossible.

Until proven false, it is simply comment.
For a statement to be libellous it has to be false. A truth is not a libel.
I would like to see some scientific tests which show what:
- a slightly wider soundstage looks like on a graph or table
- a slightly deeper image looks like
- more space around an instrument looks like
- better central focus looks like
- additional detail looks like
If a test can be developed to clearly show these individual characteristics then we may be able to test USB cables, DACs and amps for differences. Until then all we have is conjecture.

I listen in the analogue domain. I want to know if changing cables is audible in the analogue domain. Such tests would be useful for DACs, amps, music players as well as cables.All of your criteria are analogue concepts.
USB cables carry digital data, and nothing more, from one location to another.
Seriously?There was a test conducted in HFC using a cheap USB cable and a branded USB cable to scan a photo. The result was that although the image looked the same to the naked eye, the branded USB cable resulted in a file size bigger than the cheap USB cable.
Forgetting cables for a minute, can you honestly tell me that you've never heard these sorts of differences when changing a hifi component? If not then discussion ends.You've missed one very important stage.
- First test that the effect under consideration (and discussion) is audible.
If it is, then yes all on your list can be observed through measurement.
The items listed are emotional responses to changes in the signal - a changed signal can be observed as such and will fail a null test.

- increased dynamics too though this should be easier to validate

Of course I have, and no the discussion doesn't end.
I've heard such things many times but there has always been a good, demonstrable, measurable reason for it.
