Correct.Amir, am I right that the Amazon Basics cable is without ferrite(s), probably this below? It would be nice to find a shorter version, for me anyway. Thanks.

I have a Belkin Gold some place.....Can I send you a Belkin Gold USB Cable for testing. It's a go to cable that I have recommended others use.
No "ultra expensive" DAC has measured better than any cheaper DAC so far (since Ultra expensive DAC's are generally scams for people with large wallets and little sense) and even in testing with one of the best measuring products on this site; there was no discernable difference.
...and b) How can anyone quantifiably state that we know everything there is to measure to accurately and completely quantify data into audible differences?
Wait..... HOW is this wire causing a measurable difference on a DIGITAL signal?!
It doesn't. It causes a difference on the analog output signal as seen on the far end of the output cable from a suboptimal cabling/system setup. At the DAC output jack it most certainly doesn't change anything.Wait..... HOW is this wire causing a measurable difference on a DIGITAL signal?!
In order to do that with proper scientific controls in place, you'd need a pretty significant sample size (100+ participants). You'd need to set up a controlled environment where neither the experimenter nor the participants know what's being tested. You'd then run the experiment and analyze the results using statistical methods. You'll probably have to compensate the participants, so it'll get pretty involved and expensive.has anyone even attempted to A/B the measured cables
I read the post. Do we have confirmation that this is the reason? Is there a way to test for this? Either way, it is clearly making a difference so we would have to prove that the other wire is somehow defective in its design or there is something this cable is doing that other cables aren't.It doesn't.

See also my pos t#62.
Also note that in recent measurements Amir has made with USB feed (RME Adi-2 DAC which is essentially identical to the Adi-2 Pro) there is no main residual, in contrast to his measurement here... which backs up my observation...

Which cables? USB? If so, that is impossible since swapping USB cables completely stops the flow of music causing long pause until playback can be restarted. This destroys any chance of hearing small differences if they exist.Being someone with an engineering background and also an audiophile what I find fascinating is a) has anyone even attempted to A/B the measured cables since at the end of the day, we use these cables and devices to provide sound?
Yes, the USB cables at the subject of this post. Also, who says uninterrupted music = an inability to discern differences?Which cables? USB?

Based on measurements, there is no audible difference.
Auditory memory is short duration (seconds at most) so you have to switch the a/b sounds rather quickly. google "echoic memory" there's a lot of literature on the topicYes, the USB cables at the subject of this post. Also, who says uninterrupted music = an inability to discern differences?
As noted, science says that. Subjectivists of course think they can hold to memory of fidelity a year later. Funny there that they fail all controlled tests.

It wouldn't be very difficult to build a test rig allowing instant switching between USB cables.Which cables? USB? If so, that is impossible since swapping USB cables completely stops the flow of music causing long pause until playback can be restarted.

This sort of thing is the type of bias I find annoying; the presumption music lovers (and by inference audiophiles) are somehow better than the engineers who designed their stuff, and implication (virtually a statement in this case) that engineers cannot be music lovers. Balderdash.
