And responds when a neighbour asks has he done anything about the back of the house, "That's not as important; bad guys will always try to get in the front way ..." Unfortunately, electrons are very even handed in their ways of dealing with 'obstacles'. What have electrons got to do with it, in the presence of AC they just jiggle about in the cable and don't go anywhere... crenca 1 Link to comment

marce Posted April 26, 2019 Share Posted April 26, 2019 This is measurable and if its altering the analogue output then the design is flawed. Link to comment

And does he, maybe maybe not I've also been involved with electronics for over 35 years so stop trying to put me down at every chance, it is getting very boring. jabbr 1 Link to comment

We share experiences with others who may be interested in them. Audio is a hobby to us, not a scientific journal. People are free to consider or ignore our experiences as they see fit. Yet so many claims are made, so many myths passed on... Teresa 1 Link to comment

I would be surprised if there were two different USB cables that are absolutely identical in terms of all measurable electrical parameters. The whole point of the USB specification is that in the case of cables, transmission lines etc. they are kept at 90R differential impedance, that is the important figure and in that respect they should all measure the same if true USB.

marce Posted April 27, 2019 Share Posted April 27, 2019 some reading... both articles are relevant and the second follows up on the first. https://www.edn.com/design/consumer/4419643/Select-your-USB-audio-MCU-with-care--Scary-stories-from-the-test-bench https://www.edn.com/design/consumer/4424103/USB-audio--Asynchronous-is-the-only-choice-for-compromise-free-audio- I have some further comments on USB implementations on a wide variety of designs, but going shopping with the Missus now!!!!
