But Ethernet cables send high frequency 0’s ans 1’s so rapidly that a human can not comprehend it and that is fed into a DAC microprocessor that decodes it. It is less clear how you can "flavor" that digital stream of zeros and ones and effect the sound. I will agree that a quality cable can sound better if it is not dropping some of the signal..........But what makes me a skeptic is that by changing the conductors digital cables are supposed to have the same tone / flavor changes as an analog wire. I mean copper sounds neutral, silver sounds bright, Gold sounds warm. Its too much of a coincidence that the wires will flavor an artificial digital stream the same way as analog.
YMMV.......And if you think anything makes your system sound better who am I to judge. But personally I am going to pass on a $12,000 digital anything cable.
