$500 USB cable


Someone is trying to sell some fancy (used and 2 ft long) USB cable for $497.50. I am genuinely curious since I am no expert. What does this ultra expensive USB cable do to your audio system (besides transferring digital data)?

I just finished counting up all the blind testing results for cables over the past 40 years and the results might surprise you. 32,455 heard differences, 54 did not hear differences. I suggest we behave like adults and throw away the 54 outliers, pick up the pieces and move on.

An ordinary man has no means of deliverance.

Good point. Those 54 can download Deliverance on Netflix. I hear banjoes all of a sudden.

No need to guarantee either: 
Wire has nothing to do with right or wrong zeros or ones sent. DACs don't care if 'complete or incomplete zero or one' it received. DACs treat zero as ZERO and one as ONE. USB or any digital wire simply cancels out from both part of equation. That's where simple arithmetic kills all the science, hypothesis and beliefs behind. You can check answer with calculator LOL.

If you hear a difference between USB cables, it's likely that your DAC is not using asynchronous USB but rather synchronous USB. The latter is much more susceptible to cable quality than the former. Because in synchronous USB the jitter contributed by the cable can affect sound quality. With asynchronous USB there should be no difference in sound quality between USB cables assuming the receiving DAC does not rely on the USB power which any reasonable DAC won't.
